Your guide to Wrangler mods, what will u need to do what.

[Dune Rider]

Salaam and good evening all
Since it seems i have at least 2 out of the 3 things
now all what i should wait for is the bonus to be paid . then the front and back bumpers , 3in lift kit and all the related things to that lift, the black fenders (the ones u screws) and nice rims and tires.
is that all needed or there r other things?

if u tell me yes , then why dont some take the JK and doo all of it


thx all

Salaam ya Arbab,

lifting the JK for proper off-road use is not easy and in the end costly, so be careful what you do and plan each modification checking which modification will follow it, for example:

- lift kit requires adjustable front assembly, track bar sway bar
- now you put bigger tires that will require front axle reinforcement and re-gearing
- it can mean lowering transfer case as well depending on lift height
- tyres means also fenders means new rims

Again, please be careful in which modification you put and be clear about its consequences.

salaam and good afternoon to all

if the lift is 2 to 2,5in do i need a wheel spacers, if yes then what it is the recomended spacers ? 1.5in or more ?

thx all

[SSS]

wheelspacers for sure should not be wider than 1.5" !
(too much stress on axle and hub)
sometimes needed depending on your rims you want to use (back spacing) and the width of the tires!

i've decided to write the following to help our wrangler newbies decide their car mods and future plans, this will be Your guide to wrangler mods, what will lead to what

1- Lift kits:
will change the geometry of your car, centre of gravity,
options:
2": mostly no need to drop the transfer case (2" BB, not recommended)
more than 2": Drop transfer case *1, change shocks.
(Recommended is no more than 3.5" due to the fact that many other things has to be changed).

2- Shock absorbers:
with any lift you have to change the shocks, dont listen to people who tell u no need to change it if u go for 2" because u'll end up breaking lots of things due to the stiff ride (including ur back).

3- Tyres:
(- any bigger tyre than 28" will affect the performance of your car, still its not very noticeable until you go more than 31x10.5xR15
- For any tyre bigger than 31" you'll also have to change the rims/wheels to a new one with a back spacing of 4", backspacing in easy words is how far is the rim for the inside of ur car so that it wont hit at full turn)
Recommended:
- 31x10.5xR15: no need for a lift or any change of gears.
more than 31x10.5xR15:
32x11.5xR15: 2.5" lift or more. regearing is required due to big lose of power and pressure of the diffs.
33x12.5xR15: 3" or more lift is required + regearing.
(any bigger tyre is not recommended).

4- Regearing:
31x10.5xR15: no need.
more than 31x10.5xR15: regearing is required. Recommended new gear ratio is 4.56 (stock is 3.73).
Adv. = gaining the lost power and gaining more torque (huge difference even on stock)
* you have to change the rear diff carrier at least to add the new gear ratio.

Plan recommended:
3" full suspension lift kit
33" Tyres
Regearing to 4.56 with rear locker at least.
Adjustable trackbars.

so now u can calculate how things are done:
Q1: can i add 33" tyres to my car? yes, do the following:
33"-> 3" -> Change shocks -> drop transfer case -> regear -> add rear locker.

Q2: do i have to lift my car to add 31"?
No, go add it but u'll lose some power.

Other Recommended Mods:
1- Air Intake System.
2- Catback System.
3- Throttle Body Spacer.
(Air flow through is done, more HP and more Torque)

Next i'll be writing about the brands rec.

* Alternative for dropping the transfer case is to buy an CV/SYE drive shaft. (a bit expensive but will save u .75" drop of transfer case drop. not a must but recommended.

Most of these Mods comes with cost as well.
Never forgert that you may need to strip-down your car for registratation and re-built it up again.

Simple Mods can works really well.

i am planning to regear my jk. i have 33" tires and 2.5" lift kit. the gearinig is still stock (3.73) and i am planning to have it 4.88. i bought my jeep from WM and when i told them i want to upgrade the R&P they told me that the warranty will be void. i even told them i iwll buy the material from AEV and take it WM shop in mussafah to do the installation. they told me even if we do the installation for you we will void your wrranty on the car.

i called AEV and told me no that's incorrect. regearing will not void your warranty especially if you let WM do the installation.

what do you guys think? should WM void the Warranty or not? thanks.

That is why I bought RB. No warranty to be worry about!

Regarding your question, it should void the warranty ONLY if they can prove that the modification have caused the damage. Otherwise, they have no right to do so. But you know how our dealers work...

If it was my car, I would of changed the R&P in AEV and never tell WM about it!

[SSS]

Of course WM will warranty their WORK, if they put the R&P in.

But your Chrysler warranty will be void PARTIALLY for your lower suspension/drivetrain even if you have lifted your Jeep ... The Tornado mods are warrantied by WM themselves. Your Engine, Transmission, Transfercase, ECU, Dashboard electronics and other body parts are still covered by Chrysler. WM cannot void the whole Chrysler warranty for parts not affected by a mod ...

This is what I know and used to with WM ... and you should not listen to a showroom guy ... talk to the service managers in Mussaffah.

so basically what you are saying is that my Chrysler warranty on the drivetrain (R&P) will be void but WM will cover that part since they are doing the installation (like the lift kit and suspension they did). if thats the case then i am fine with it but i have to make sure that they agree to that!!

they do not warranty the parts themselves ... how can they warranty superior stuff or teraflex coils or shocks...
they warranty that their WORK was done professionally ... as any big reputable workshop will do. correct torque specs, professional body work, professional gear experts etc etc... (if your R&P break of course you are in deep shit ... bad material or bad set up ... you will bounce from one wall to the other ... so your risk... if a shock fails it is much easier to find the culprit)

Hi - question for Moe ..... I just purchased an AFE catback from Icon-Auto (Dubai) for a 2011 JK. On-road it does not offer any noticable difference except alot of general exhaust noise and low frequency noise, which is very unpleasant for the occupants of the car. My question is whether one can make such a Catback quieter and if not which catback model is much quieter but still gives the performance increase ?

Thanks - Big Stinger

Thamks for that really useful info megamoe and i could understand it...

Hi Adrian,
about JK Performance tuning ... it's all about increasing the airflow through the engine - it begins with the Cold Air Intake, new High Performance Headers and a High Performance Catback.

If you're going with dbPerformance or Gibson Catback (preferable the dual tip) you'll gain significantly better airflow (together with a CAI - such as K&N or the dry CAI's from AL Futtain) ... K&N delivers better performance - but you'll have some problems because they're not dry but a bit oily - so they tend to get sandy ... But Icon can clean your filter - so you should get a 2nd filter by then. I think i've also a 2nd one. (Maybe even the K&N completely - but it's with my car - so still in the garage ... together with the old engine) .

So go first for the CAI, then for the Catback, then if you're brave for better headers. Then you can get a Diablo Trinity / Predator and do some more tuning. ( I've a diablo as well soon for sale ... ).

But one thing : I will not get quieter... It will get louder .
IF you add another muffler to make it quiet again, you restrict the airflow again - and your performance gain is lost ... maybe even more...

Guys,

The write-up by MegaMoe is great, yet certain points are specific to Jeep TJ i.e wranglers (1997 -2006), hence owners of different wranglers like JK, CJ, YJ etc. need to understand the differences and applicable mods for each specific model.
