How much lift before I start messing up the guts?

Hi everyone. I was looking for a lift kit that can offer me performance to take on any decent trail. Not really anything too crazy, but enough to take on most trails. I have read on here a couple different answers to this question. How much lift can I get before I need to mess with the drive shaft and other components?

Also, I am looking at the Teraflex 2.5" lift with shocks. For $700, what kind of lift would you recommend? I would be willing to go to 3.5" if I can get away with it.

TeraFlex JK 2.5 inch Lift Kit, W/Shocks

Buy a 2.5" lift with 4-6" Shocks if you want to get the best bang for your buck...

Anything higher than 2.5" of lift you start needing to address suspension components that add up to a lot of money.

When staying under 3" of lift you avoid constant driveline angles which prematurely wear out drive shafts.

Stay under 2.5" of lift. No matter who you buy the suspension from, ask them specifically for 4-6" long shocks that will give you best of all worlds, on and off the road.

What exactly do the 4"-6" long shocks do? and how can I ask for them when I am buying a kit?

i always place my orders verbally. i dont take chances with internet buying on my modifications.

so when you talk to the sales guy, tell them you want the teraflex 2.5" lift without their shocks. I dont recommend their shocks. look into bilsteins 5100s. they got a part # for a 4-6" shock. so tell them you want a 2.5" teraflex lift kit without shocks... theres a part # for that and give them the part # for the 4-6" bill shock.



but be aware that you will need spring retainers to retain the spring from unseating. not a big deal at all and it takes 10 minutes.

2.5 TF Without Shocks:

Tera Flex JK 2-door 2.5 inch Lift Kit, W/out Shocks (1351002)


Bilstein JK 07-12, Front 5100 Series Gas Shock, 3.5 Inch -5 Inch Lift

Bilstein JK 07-12, Front 5100 Series Gas Shock, 3.5 inch -5 inch Lift

Bilstein JK 07-12, Rear 5100 Series Gas Shock, 4 Inch Lift

Bilstein JK 07-12, Rear 5100 Series Gas Shock, 4 inch Lift


You WILL need these for sure:

Front Coil Spring Clips

Rock Krawler Catalog


These are optional, but I HIGHLY recommend them with every JK Suspension Lift. (These are for dialing in caster and much needed road stability)

Clayton JK Front Lower Control Arms

Clayton JK Front Lower Control Arms 1808100

depends on the up travel or collapsed length. 90% of the time, with the lifts giving more than advertised height, you're going to safe.

I'd recommend skids if you keep the lift height low. I currently have a 2.5" spacer lift and go pretty much anywhere I want. I just drag over everything.

Hey Pluke, I took some notes too, I have that lift but was waiting on what shocks to get(i'm running stock ruby shocks with extensions). I'll take the advice and do the longer shocks with the spring retainers.

Great info on this site!

From everything that I've read, 2.5" is the ideal lift if I want to avoid the issues that come with going over 3". But when researching the RK lift, it seems that most people net well above 2.5". So are they encountering or going to encounter the same problems that a higher lift brings anyway?

I was all set on going with 2.5" RK. But I don't want to net 4" of lift an then have the very problems I'm hoping to avoid. So I'm starting to lean toward the 2.5" AEV to actually stay at 2.5.

Am I missing or not understanding something?

The 2 doors get more lift with RK 2.5's
And yes we do encounter issues.

if you guys are running longer shocks you'll need to address the front drive shaft on the 12's and 13's. forgot to mention that.

i was running a 10' and didn't have that issue because i notched out my skid plate. for you guys it's a exhaust issue.

Darn it.

I will have a 4 door (hopefully by tomorrow). I think my head is ready to explode. I need to step back and take a break. At least until after the New Year.
