Will I feel better Performance?
 
Hi Guys,

Well, my Jeep build will begin on tuesday and I am wondering if I will really feel performance gains when it is complete.

I am spending a little over $4,400:eek: for the following and I am told I will absolutely feel the difference with the gearing.. Ok, here is the before specs:

2000 Wrangler Sport, 3:73 gears, D44/D30.. Performance mods: AEM Brute Force w/ spacer and Banks Monster cat back..

After (should be complete by the end of next week):

ARB Air Lockers front and rear w/ CKMA12 Compressor and tire inflation kit.

Rear diff (D44):

ARB 30 spline, Alloy USA chromoly axles, ARB diff cover, complete axle overhaul kit, and Superior 4:56 gears.

Front diff (D30):

ARB 30 spline, Superior Axle 30 spline chromoly inners, ARB diff cover, complete axle overhaul kit, superior 4:56 gears, front axle tube seals, and high strength U joints.

Basically, I was initially going to just do the gears, but I received 50% off labor, and 10-20% off parts, so I was able to come up with rest of the cash (and the blessing of my wife god love her). The problem I am having is that I am dumping a ton of cash (of which consists of selling a few of my beloved guitars) and not feeling the benefit of performance gains.. I realize that when off road, I will most definitely feel the ARBs, but will the gears give me some driving pleasure when not off road?

Sorry so long winded here guys, but I really just need a little reaffirmation for spending this kind of money during a down economic period.

Timber.:D

Performance? On the road, the gears should be a great help to you. 4.56's should get rid of some of the lugging from hauling around those 33" tires. That's about it on the pavement.

Off road however, you will have huge benefits! I don't know how much time you spend in the rocks but having those lockers will allow you to get up and over a ton of obstacles that you were bypassing or winching over before!! Plus, you shouldn't have to worry about breaking axle's with the new shafts and u joints.

AND with those diff covers, you won't have to pull the cover off to swap your diff fluid (which, you'll have to do at 500 miles with the new gear set).

Money well spent IMO!

Thanks Stevens...

Yeah, 4wheelparts threw in the Rear diff cover and I elected to add the front after the fact just because of the drain hole and the fluid change at 500miles.. Besides, they look cool as hell..:D Oh, I heard they actually have performance functionality as well.. I have read the they hold the carrier in place better than stock covers....:confused:They said the gears will return the jeep back to stock-type performance.. He said with the intake and exhaust i have, I should see even better performance over stock.

I typically spend most of my time in the TSF of Oregon, so yes, I will meet a rock or two on my travels.

I have been watching youtube videos on ARB air lockers for the past month (the time it took them to round up all of my parts) and have seen them in action on the trail and yes they are expensive, I am think they are a must.

The 4.56 gearing will make a HUGE improvement, you'll love the results.

However, leave the throttle body spacer on the store shelf and save your $$$ by not wasting (!) your money with it. Under the type of throttle body our TJ 4.0L engines have, throttle body spacers do nothing. Spacers can provide dramatic gains under carburetors and the older style of throttle body that had the fuel injected directly into it but the TJ uses a more modern throttle body where nothing but air passes through it.

A throttle body spacer does nothing and is a 100% waste of money where a TJ 4.0L engine is concerned. :)

No worries Moa, you will get there my friend.. 4wheel parts has a 50% off labor special each year around Christmas. I wouldn't have known about this if it wasn't for the previous owner of my Jeep. He and his wife came over to check the progress of my mods and he told me all about it. This build at retail would have been over $8K, so i guess $4,400 isn't all that bad..

Hey, I noticed in your sig that you have the JKS ACOS? How do you like them and how hard were they to install? I have been eye-balling them for a little while now.

Thanks Jerry,

I am really looking forward to the gearing... even with 3:73 gears it currently has, there is a lot left to be desired.

The Spacer came with my AEM brute force, so she is already installed... Does it hurt anything by it being installed?

they are great.. the rears were a pita bc you have to drill out 3 bolt holes for EACH acos.. but the fronts were as easy as normal coil spacers to install..

i would have the money to lock and regear my jeep.. but over the summer i did the axle swap, then right when i got done i bought a new dd.. so now i got car payments of 380 each month =/

Yeah, after i absorb the $$$ from the Lockers and such, I plan on doing front and rear JKS control arms, ACOS, JKS Quicker Disconnects, and an Engine Skid (still undecided on which warn or skid row).. I should be done then:redface:

So, where did you have to drill the holes on the acos rears?

No, not unless it whistles as some do. :)

when you get the rear acos, there is 3 holes spread even on the base of them, you drill up into the spring buckets on your frame, pretty self-explanatory when you actually see the acos.. the problem i had was that the drill bits kept going dull after drilling through about 1/4'' of steal on the frame

I am very pleased with the results

Hello All!

Well, I brought my Jeep home from 4 wheels parts today with her fresh axles and lockers and I cannot be happier with the performance. The jeep drives so much easier than what she used to with 3:73s.. If you are on the fence about re-gearing, please get off the fence.. It will be the best decision you will make..

Anyway, I have played around with the compressor in that I have made sure that all of my other vehicle tires are aired to the correct pressure...:D Other than that I have just absolutely enjoyed driving this jeep with much new found performance. I think the exhaust even sounds deeper.. :p

Here is a link to the end results... Sorry the picture of the compressor isn't that good... She is tucked way in there.

Thanks Stevens.. I am giddy like a school girl over here.. It was a pretty spendy job, but i think it is worth every penny.

It is going to hurt real bad when I begin to scratch her up!
