Neew info on a 8.8 axle and Poison Spider bracket kit

Got a lead on a 8.8 (same ratio ) the explorer brackets have been removed, its been ground down and been sprayed with primer. they are selling a Poison Spider TJ bracket kit with it. I cant find any info in the Poison Spider kit.

I can weld, and know other welders that can help...but don't know differentials and proper angles to put the brackets in at. Is this a DIY project (like that come with directions!) or do I need a Dif shop to fab it up? Am I going to need more than the axle and kit to move forward (literary) like new control arms or anything.I know I'll need brake lines and u joints to merry them up.

I appreciate any info from someone who has welded the brackets up before.

Pm solman on here he has set a few up. Your prob gona want control arms but you can set one up without them. Your gona want to make sure you have a sye if you plan on one because the geometry of how the diff and tcase output changes based on if you've a sye or not. So of you change thn it will be hard to change your setup. You'll rotate the axle and have a chance of having your coils springs crooked and shocks running into coils and crazy stuff. It's better to have it set up the way you Plan to keep it.

I'm a it confused about a when you need a SYE. My lift kit actually lowered the t-case and the mounts for the control arms to keep the geometry close to the same while achieving lift. When is a SYE necessary?

The differential case is offset to the pass side by 3 inches.

I did my own 8.8 swap in mine, and I pulled out my d35, then put the d35 and the 8.8 both on the same pair of saw horses facing the same direction. I used a magnetic angle finder on the flange of the 8.8 and across the yoke of the d35 to ensure that they were both at the same starting point. Then I measured the position of all the brackets from there (and added in a few degrees of rotation to each of the brackets since I have 5.5" rustys springs). I also took advantage of the situation and rotated my shock mounts much higher than they were on the d35 so they are no longer a ground clearance issue.

From what i have been gathering that seems to be the way to go. Compare it to the D35 that comes out and match, with adjustments for the fact that the D35 mounts were stock before any lift.

I was hoping to have the 8.8 welded up and painted to swap in fast, its my DD and cant stay down for long, but am finding out that short of someone having a jig that does 8.8 - TJ swaps all the time, both axles have to be out before the welding.

Absolutely not; a friend of mine (solman who GoldenSahara00 referred you to above) setup an 8.8 for me. It's all ready to be picked up, without ever having to remove my old axle. If you can weld, you can easily set it up yourself, it will just take some work. I'm like you, I need to be able to swap it out quickly. I can't really afford to have my Jeep down for very long right now.

Check here for more info than you ever cared to know about 8.8 swaps:

8.8 FACTS, OPINIONS & HOW-TO'S (F.A.Q.) - JeepsUnlimited.com Forums

Solman has setup a few 8.8s now, so if you need advice you can always shoot him a PM. He's a pretty good guy and I'm sure he wouldn't mind helping you out.

I appreciate the lead. i am going to look at it in a day or two and probably grab it to have, then work out the details from there!

On the 8.8 write up I found this section:

What do I need for a swap into a tj?
Here are some things I used:

-TeraFlex Bracket kit
-ARB
-U.S. Gears 4.56
-Master install kit (Timken)
-Crane diff cover
-Napa brake line kit P/N 380528 (x2)
-T-hose NAPA P/N 380889
*TJ Rubicon brake cables 52128428AA and 52128429AA thanks jeepit!
-ZJ E-brake cables (drivers and passenger side)
Mopar P/N 52008904 & 52008905
NAPA P/N 95342 (right) 95347 (left). (not for YJs)
-Driveshaft adapter: Spicer 2-2-1379
-Flange bolts Ford P/N N800594-S100 (x4)
-'03 TJ Rubicon (w/disc) proportioning valve P/N 5083808AA
-3/16" hard brake line about 40" & 18"


does this seem to cover it on other items needed, or is it a more of a case by case basis?

Well if you look at your list, everything like the ARB, gears, diff cover, etc.. aren't exactly necessary to run the 8.8, they're more it's nice to have and eventually what you'll probably want to work towards. It's more of a case-by-case thing. I'm choosing to do things incrementally to spread out the spending; I'm buying a house and getting married in a few months so lets just say I'm a little strapped for cash right now.

For example, this is what I'm doing. Bob (solman) found an 8.8 with 3.73 gears, which my Jeep conveniently is running. This will allow me to run the 8.8 this way until I am able to regear my Jeep. Basically, all I had to buy to complete the swap is:

* The axle
* A bracket kit: there are many of these out there, pick what works best for your situation
* Rotors, calipers, and brake pads
* Brake lines to tap into existing hardlines
* E-brake cable
* Adapter for u-joint/axle yoke
* Fluids

Everything else is pretty much on a case-by-case basis, or as you want it. Eventually I'll be regearing, getting a locker, installing the Superior 8.8 kit, heavier diff cover, etc. but what I have now will let me run the 8.8 for a while until I save up to finish the build. If you want you can do it all at once, it really doesn't matter. I just chose to do things a little at a time. Like I said, that thread above from JeepsUnlimited covers all of this and more.

I hear ya, thats how I am on ever thing I do to the Jeep.

the 8.8 is the right ratio, comes with the unwelded bracket set, so other than connecting the brakes and driveshaft I can run it until I save more money

Should be able to; while you're welding everything else up, take the time to do things like welding the axle tubes. That thread gives some good info on those little things that are nice to have done.

If you want to save some cash at the welder or fab shop, go with the truss and bracket kit from Artec Ind.

Awesome kit, the truss is an awesome addition to any rear axle and isnt much more.

It also eliminates all guess work and measuring for putting the brackets on a naked 8.8.

When you get tired of scraping your belly and low-hanging mounts all over the place. A t-case drop is just a cheap "bandaid", as are control arm drop brackets. You're killing your clearance, among other issues.

x2!

If I didn't already have an 8.8 set up under my rig, the Artec truss and bracket system would be what I would go with.

he says he has bought the Poison Spider Bracket kit already, just clearing out projects he has laying around. I cant find any info on Poison Spider and their bracket set-up on their website though. I'm only buying this one is because (well, other than having a D35 with a tweaked driver side wheel stud "plate") is he was putting it on a TJ, from the right doner explorer with 31 spline and disk brakes AND has my ratio already, not to mention its had the old mounts ground off and is prepped and primer'ed. Only thing I don't know is if the ring and pinion are in good shape, but I'll check it out when I go look at it.

A one inch drop can make a huge difference on alot of trails. Thats why people are willing to spend a pretty penny on things like a tummy tuck. Plus even without a drop the stock skid plate (shovel) is like a fricken rock magnet it hangs up on everything.

What Imped meant was a T-case drop kills your clearance when compared to a tummy tucked set up which can give up to 4" of clearance in the breakover angle department inbetween the front and rear tires measured at the frame rails. That clearance is helpful for climbing sharp edged obstacles, waterfalls, hills, driving over large rocks and fallen trees.

A tummy tuck done right can cost as much as a high quality lift kit does, but it allows a Jeep on smaller tires and smaller axles to be able to go places that would take much larger tires, and a lot more lift, plus larger axles to be strong enough to run the bigger tires... So in my eyes the money spent on a tummy tuck is well worth it.

Heres a thought also, is there a part number on the diff case...i am going to look at it and just realized I dont know what to look for. i was going to bring the measurements with me to verify, but he is selling the 8.8 and bracket kit so cheap that I don't wanna get taken and buy something that isnt what it says it is. .

original ad asking 300.00

Poison Spyder kit for installing Ford 8.8 axle in a Jeep TJ. Axle is from a tow-package Explorer, disc Brake, 4.10 geared. Kit includes coil spring perches, shock mounts, and brackets for the four point Jeep diff set up. No time to install it in mine.. This diff and axles are far stronger than any stock jeep stuff and add disc brakes to your rig.

Just had a good conversation with the guy. Sounds like a good deal. came from a 97 explorer with tow package,has limited slip, calipers may need to be rebuild or replaced, original mounts have been ground down and media blasted and primed. I've successfully talked the wife into it, picking up Saturday if all looks good. He's a jeeper and is only selling to repair his main rig that some critters chewed up his wiring harness.

On top of it all we work in the same industry and we know some common people.

If he's correct, the tag on the pass side of the rear will say 4L10 on the bottom left corner if you're looking at it, or if it's not there....pull the cover and the ring gear should say 41 10....41/10 = 4.10

A 1" drop on a skid that's already dropped 4".......

If that's NOT causing you issues, you're on the wrong trails. I've got 20" under the belly and it causes me issues.

I've got 16" under the belly and my trails are cut through woods, over the hills made nasty by mother nature and open country wheeling. But when I am done I have to drive it home, clean it up and use it for work and what the rest of life throws at me. A TC drop isn't ideal for the hardcore but spending 10k+ on a hardcore setup to just explore the woods on a weekend camping trip with family and friends isnt ideal either. My kids dont like peanut butter and jelly sandwiches and Ramon noodles that much!

This 8.8 isnt for a big build up, it's to remedy a bent axle end and not sink money into a D35.

I feel stock guys take solace in knowing they have a convertible that can handle anything daily driving throws them

mild lift guys like knowing that a dead end rock road doesn't have to be the end of the road,

and hardcore guy's like knowing if they ever need to cross the Rockys without a road in sight, they can climb the whole damn mountain range if they feel like it.

Its to each his own and how they play. I respect them all, from the 6" lift on 35's MTR guys who never leave the blacktop to the stocker who is heading to MOAB.
