PLEASE READ THIS IF YOU ARE INTERESTED IN PURCHASING ONE OF OUR FORD 8.8 TJ AXLES OR ALREADY HAVE ONE:
There is a vast amount of information and questions that go along with a custom axle so we will do our best to answer most of them here for your reference. We will start with the options or the drop down tabs listed online.
LOCKER OPTION: You have a choice of lockers if you would like something not listed we can still install but we do not stock it, with the exception of an OX-Locker, we do stock those but have a hard time keeping them in stock do to availability. So any option not listed will require a few more days lead time.
POSI OPTION: If you think a Positraction/Limited slip fits your needs better than a locker we have some options, again if you would like something else we can install but it is not a stocked item. All items listed are in stock. The factory Limited slip is a good cheap option for traction, we rebuild them using the most efficient clutch stacking to give you better performance and longevity over a stock one. If you choose a used factory unit non-rebuilt we do not inspect clutches only the spider gears as these are visible from the outside.
ADPATER FLANGE/YOKE OPTION: The Ford 8.8 uses a flange style yoke, your jeep uses a conventional style u-joint yoke. In order for your driveshaft to bolt up you will need to purchase a new U-bolt style conventional yoke or an adapter flange. The U-bolt style yokes are American made forged yokes and are of the highest quality. This eliminates extra pieces in your already short D-shaft and gives you a new yoke versus a used yoke. It also will give you 3/8” more driveshaft length.
BRAKE OPTIONS: We offer new brakes to you at a very low cost and put them on for free. The prices listed should be the same or lower then what you would pay at your local auto parts store. Remember these are used brake parts and although sometimes they are good your axle will look so much better with new brake components. We do highly recommend new e-brake shoes as moisture gets trapped inside the rotor and will rot the shoes out. Also it is difficult to install the e-brake shoes with the shafts installed so if we are going to be replacing parts inside the diff now is the perfect time to install the shoes. If you choose the used brake option we will make an attempt to give you good used parts but they are used
DRIVESHAFT STYLE: The answer to this option will determine the pinion angle your 8.8 is set. We will go further into this later.
ADD EBRAKE CABLES: If you want a functioning e-brake with your new disc brake set-up. These cables will swap right in.
ADD DIFF COVER: We have 2 aftermarket options for differential covers. The solid covers which are heavy duty cast pieces, they have a lifetime warranty and are of great quality and a very affordable price. Our second option is the 3/8 bent and welded steel covers, these are also great covers with a lifetime warranty. Both covers will offer you ample protection and give you more fluid capacity. For the money the cast covers are a sure bet, the steel covers are very useful if you will need to weld to the cover for any reason. One such reason is if you were doing a triangulated 4 link set up and you wanted to tie the cover into the truss for additional strength. ***Please not always fill Ford 8.8 through factory fill plug in front of differential not threw aftermarket cover fill plug.
FINISH: We have 2 Paint options Flat Black and Rustoleum Hammered Finish. The flat black gives a nice, clean look and is functional. The Hammered Finish is more glossy and will be more rust preventative.
FACTORY GEARS: We have 4 factory ratio options available: 3.07, 3.55, 3.73, and 4.10. The 3.07 and the 4.10’s are getting difficult to source so you may want to call on availability for those two ratios. By choosing the factory ratio you will be getting a used gear set, if you do not purchase the "Freshen Up" option we do not inspect the gear. However if the gear turns out to be in poor quality we will ship you a good used replacement gear.
FRESHEN UP FACTORY GEARS: If you choose the used gear option then consider this option as well. We will totally disassemble the axle install new differential bearings, new axle bearings, check the axle shafts for run out, inspect spider gears, and insure ring and pinion is in good condition. The only thing we do not inspect is the clutches in a used limited slip if that was an option chosen.
REMAN UNIT W/ NEW GEARS: If you choose the "Reman" option with new gears, you will receive new gears, new differential bearings, new axle bearing and seals, spider gears inspected, shafts checked for runout, and will be set up properly for years of service. This option is covered by our five year warranty parts and labor warranty on all replaced parts. Our warranty Policy will be covered in more detail below.
SHAFTS: You have three options for shafts 1. Good used shafts; these shafts are inspected for runout and for pitting around the bearing surface, typically the used shafts will give years of service and take serious abuse off road we believe that they will hold up to 35 inch tires with little issue. 2. Aftermarket 1541H axle shaft, this is a high quality aftermarket shaft made of a stronger alloy then stock. It is not chromoly, but they are induction hardened (a heat treat process that insures long life and strength). Currently there are no aftermarket c-clip chromoly shafts on the market. These are the best c-clip axles available. 3. Superior C-clip eliminator kit know as the “Super 8.8 Kit” This is a great kit that offers 4340 chromoly induction hardened shafts, it also upgrades your wheel bearings to Set 20 bearings these are the same bearings that are in big bearing 9” housings commonly found in heavy duty semi float axles. Each bearing is rated to support the entire weight of you jeep. These shafts have a lifetime warranty and do away with the C-clips as well as widen your axle by 1.5 inches over stock. If a full spool is chosen this option is required. We believe these shafts will hold up to a 37 inch tire with little issue. If you would like to run a tire bigger than a 38” we have Dana 60 and other options available.
SUSPENSION LIFT: This option combined with the D-shaft option will determine the angle we set your pinion which affects the trac bar placement and your link geometry. The stock pinion angle of a TJ is around 6 degrees this means your spring perches are at zero and your pinion is pointing 6 degrees above zero. If you lift your jeep above 3 inches the lift manufacturer will likely include a trac bar relocation bracket. As you lift the frame of the vehicle the trac bar effectively gets shorter and out of alignment ideally the trac bar should be within factory spec to control body roll and to keep the axle centered. There are 2 common trac bar relocation brackets one is 2 ¾ inches higher than stock the other one is 3 inches above stock and is bent forward towards the front of the vehicle. The forward mount trac bar brackets are typically include in the 4 inch plus kits with adjustable upper control arms. The adjustable upper control arm lifts are designed for use with a CV driveshaft. With a CV driveshaft your pinion angle needs to be about 1 degree lower than your driveshaft angle. On a 4 inch lift w/ CV driveshaft the pinion angle is usually between 17-19 degrees. With a stock axle you would need to rotate the pinion angle 10-12 degrees up. This will roll your trac bar bracket backwards and the stock mounting location will now place your trac bar on your gas tank skid, roll your shock mounts underneath your axle. It will affect your spring perch mounts and control arms as well. The bent forward trac bar mount will move the trac bar bracket off the gas tank skid typically but leave the rest of your geometry off of factory spec. In order for you not to have to get an adjustable trac bar and uppers and keep your stock geometry we set your pinion angle as close as possible to what it should be with your current suspension and driveshaft set-up. We error on the low side for a few reasons. If you already have adjustable uppers they can be the same length totally collapsed as stock uppers so if we set your angle to high you would not be able to rotate it down. Secondly if you do not have adjustable uppers and pinion angle is slightly low there is a good possibility you won’t have any noticeable vibrations with a CV driveshaft and will not require adjustable uppers. If you do not have an SYE (Slip yoke eliminator kit w/ CV driveshaft) but anticipate installing one in the near future depending on your lift we recommend splitting the difference in the angles. This way you will probably have light vibrations without a slip yoke shaft and then when you upgrade to CV Shaft you will only need to rotate the pinion angle a few degrees and not disrupt your geometry as dramatically. **** As with any custom suspension and axle packages we cannot guarantee that you will not need adjustable Uppers and a trac bar to completely center and get your pinion angle perfect. Every suspension system is different, however we make every feasible effort to make these bolt in to complete stock components or aftermarket parts*** Further Notes: COT: Continuous output torque rating MOT: Maximum output torque rating -------------------------------------- Dana 35 rear axle COT: 870 MOT: 3480 Dana 44 rear axle COT: 1100 MOT: 4460 Ford 8.8 28spline COT: 1250 MOT: 4600 Ford 8.8 31spline COT: 1360 MOT: 5100 Dana60 semifloat COT: 1500 MOT: 5500 Ford 8.8 WMS is 59 5/8 a Stock TJ is 60.5. Pinion Offset of a D35 TJ is .75 and the pinion offset on a Ford 8.8 is 2.75 SHIPPING AND HANDELING: We charge a flat $200 dollar fee for palletizing and shipping your axle. If you provide a commercial address for us to ship the axle we will charge you actual shipping charges and no handling fee which is typically less than $200. The $200 dollar fee does not include lift gate service. The axle weighs 260Lbs so they can be unloaded by two people from a freight truck. If you require lift gate service or cannot have anyone available to assist the driver for unload a $60 dollar lift gate fee can be added at your request. WARRANTY: Our REMAN units carry a 5 year warranty on all new parts i.e. bearings, seals and ring and pinion. This is a parts and labor warranty. Used shafts are not covered. Used Spider gears or case assemblies are not covered though we will provide good used replacement parts in the event of a failure. All aftermarket lockers and Positractions carry the manufacturer’s warranty only. In the event of a failure the customer will be required to ship the axle to our location at their expense and we will repair and ship back free of charge. If there is an immediate failure or the failure was a manufacturing defect ECGS will cover all cost associated and the customer will be reimbursed the customers shipping expense. In short we guarantee that this axle will be set up to the highest quality specifications in our control. Lack of oil will not be covered under warranty or improper break in. INSTALLATION: The Ford 8.8 axles are a bolt in axle, the brake lines are already plumbed for you to connect your center axle brake line. Your factory breather was mounted in conjunction with the center brake line mount, breather is now just under the track bar mount and a mounting stud is provided for your center brake line. Installation requires Installing springs, connecting control arms, trac bar, sway bar, bleeding brakes and adding gear oil. It will also require the installation of the adapter flange to your driveshaft if purchased instead of a u-bolt style yoke. GEAR OIL: THESE AXLES ARE SHIPPED WITH ASSEMBLY LUBE ONLY. FAILURE TO ADD GEAR OIL WILL CAUSE IMMEDIATE FAILURE AND BE VERY EVIDENT. ALWAYS FILL FROM FACTORY FILL HOLE NOT AFTERMARKET COVER FILL HOLE. We recommend Lucas 75w/140 gear oil, Lucas 80w/90 gear oil is also acceptable. We do not recommend synthetic fluids. IF you have a factory limited slip or any clutch style limited slip a limited slip additive will need to be added. TRANS-X makes a good additive that is available at any auto parts store and we also have it available for purchase. QUESTIONS COMMENTS AND CONCERNS: If you have further questions and require assistance in purchasing or installation do not hesitate to call us we make every attempt to answer the phone from 8am- 630PM M-F or later Eastern Standard time. We are also available 24 hours a day 7 days a week via email Chase@eastcoastgearsupply.com We understand that this is a large purchase and will make every attempt to insure the process is as smooth as possible.

I have an 8.8 built up by ECGS. So far I am very pleased with it. Regarding your original post, my comments are in RED.

LOCKER Ox Locker
If that's what you want that'll be fine.
You selected a locker above, so you can ignore this option.
1310 Adapter Flange
I ponied up the cash for a 1310 yoke. I didn't want the adapter flange
New Pads/Rotors/Ebrake shoes
Here's the only thing about this axle (Or ECGS, really) that irked me. I paid for new pads/rotors/Ebrake shoes. My brakes squeaked from the first mile until I changed them. I've only put about 1000 miles on the axle, I just got it... I called and they said they were sorry to hear that my brakes were squealing, but I was the first person to ever complain about that, then told me what model Explorer I needed to ask for replacement brakes for.
Both E-Brake Cables
I bought the ebrake cables as well. They fit perfectly. If you go with adjustable upper control arms, (you should) you'll have to pry the mounting bracket off the new cables. No biggie.
Gear Ratio- Reman Unit
Superior C-Clip Elim Kit
C-clip Elim kit isn't needed, because if you break an axle, it will stay in anyway because the rotor will hold it in.
I did the 4"-5" as well. 2.5" OME springs plus my TT, which was 2.5" more shallow than the stock skid.
Fit and finish are awesome. I bolted this thing up by myself and it fit perfectly. The quality of the welds and craftsmanship are very good. If you didn't know it was a Ford axle you'd swear it was a factory Jeep axle. Does that address some of your concerns?
that helped a ton but the 4-5" what is that, i thought that was askin my lift size?? also did you do the c-clip eliminator, i might just cuz a the chromoly shafts....
I see you have a 4" lift. What Transfer Case skid do you have and do you have a TC Skid drop? Do you understand why they are asking about how much lift you have? They will weld the brackets on the axle tubes a closely as possible to where it needs to be for correct pinion angle. Adjustable upper control arms will still be needed, if you don't have them already.
I used good stock shafts without c-clip eliminators.
I ordered my HPD30 and Ford 8.8 with 4.88s from ECGS last July. I opted for the new e-brake shoes and e-brake cables, but got used pads and rotors and they had a ton of meat left on them. I did not get a locker, though I should have. I got the adapter flange, but should have spent the extra $ on the yolk version. Chase talked me out of getting the C-Clip eliminator, he told me the stock shafts will hold up just fine. That sold me right there. Very happy with them. I had an issue with my 2.2 shock rubbing against the brake line, and they sent me shock extenders for free. They have since changed how they run the line. For both axles shipped I paid $2,200. Again, not locked, just basic setup. When I ordered mine, they didn't have all these extra options now. I ordered them on a Monday, and they were at my local USP yard on that Saturday. It also bolted up with zero issues. I installed them with help of my dad and a friend, so any questions let me know.
I ran my stock ones for about 4 months and had bad vibes. Installed a Rugged Ridge SYE, Tom Woods DS and Rough Country Adjustable Uppers and that eliminated the vibrations. You will need adjustable upper arms.
don't mean to interject, but please clarify: you paid $2200 total for both or $2200 each?
Yes, I paid $2,200 shipped for the axles. I called them, talked to Chase, told me what I needed and didn't need and told him how much I had to spend. And he build me exactly what I wanted w/o lockers for $2,200. I got the basics, but couldn't be happier with the set up. For the HPD30, I swapped over my knuckles, hubs, brakes and shafts to keep the cost down. So basically it was just the housing with 4.88s installed. Here is what I ordered, arrived at my door step, helped the truck driver get them off the truck and I bolted them in. ECGS was excellent. If I could order them over again, I would have saved a little more and got lockers.

that's nuts, even with lockers installed it shouldn't be "that much" more...I was looking at dropping almost 5gs for brand new G2 D44s w/ OX in the rear and Detroit TTs in the fronts...which I know was still a decent price.
Tell the truth.
