A Lot Of Body Roll with 2" Lift and 245/75?

Elt31987 · **Posted:** Tue Sep 22, 2009 2:36 pm

So i brought this up on another forum but wanted your guys opinion because it seems a lot more people have lifts here.

So i know there's body roll in lifted jeeps but i didn't think it would be this bad. I have the Daystar 2" Spacer with Skyjacker Shocks in the Back running 245/75 ATB TreadWright Tires(Look Like BFGoodrich AT KO). When at speeds above say 50-65 there is terrible body sway to the point where i don't want to switch lanes lol. Is this normal or maybe something isn't tightened? I also raised the PSI to 45 to test a harder tire but same thing really. Maybe its the spacers but before i put the bigger tires the sway wasnt that bad.

I wil blame the Shocks..... But other will have to chime in....

The shock may not have enough to them to work the way you need them to.

I know other switched to Bilstein and others may have gone another route.

But the reason was, the shocked needed differant Valving than what Skyjacker made. to prevent this Roll...

Do you mean the Shock didn't have enough in terms of length due to the lift or didn't have enough stiffness to prevent roll? It weird because the roll wasn't bad at all with the lift and stock tires but once the bigger tires went on it was a different story. Does anyone else have the same tires and the same size TreadWright ATB 245/75/16?

First, is the tire a LT rated tire? A the stiffer the side wall, the less body roll......

How ever in this case I think it is the shocks. What is the P/N for the shocks you used?

Well the tires can help to make a unknow problem worse..
But let digger help out, he understand the shock thing more than i do...

A "LT" or "P" rated tire will not vastly effect body roll,either does shocks(they help but not as much as you think).The 2 main things that control body roll is springs and swaybars.

X2 and I would say the sway bar help more than the springs. If your afraid to switch lane on the hiway theres something very wrong with your KK. I got 3'' of lift and 33'' tires and I take corners as fast as when it was stock

I have the Daystar 2" lift with a couple extra iso's in the rear, BDS shocks and 255/70-16s BFG ATs on 16x8 eagles and it handles and corners great at highway speeds. It feels nice and sturdy on the corners to thanks to the wider offset wheels. It could be your shocks or the cheeper tires c

see man I told you over on jeep forum (im snowboard49dude) that it could be ur struts/shocks... :lol:

Ok, now is it possible to install the rear coil upside down or is it the same on both sides?

Nope, they are the same top and bottom and left and right

Was thinking maybe that was it. I mean the sway wasn't that bad with the lift and stock tires. The Tire says Load is E and LT245/75/16. The SkyJackers are H7088 Hydros. Like i said the sway wasn't that bad with the stock tires but got bad with the TreadWrights. I didn't think just because it was retreaded it would be that bad, or maybe it isn't the tire i don't know

I had the TKO on my truck much much smaller size..
For the first 500 miles it was freakky to drive...

The tread made the truck squerm all over the place.
These tires where used as well...

It might just be you...
Give it some time and the feeling might go away...

Or go run a few twisty roads at normal safe speeds to break in the tires.

Ya they do seem to squirm, maybe they will wear a bit and seem to get better. Now were yours TreadWrights or some other brand of retread? But it isn't just me Ive had a few friends say its pretty bad. Its definitely a lot more unsteady, i don't mind a little more sway but this amount of sway is ridiculous.

Ive Emailed TreadWright explaining the problem and asking if any of their customers have had the same problem

I have the Rock Krawler lift with Skyjacker shocks and haven't had any issues with body roll and I thrash mine off-road 2/3 times a month. My Skyjackers are H7071.

Elt31987 · **Posted:** Wed Sep 23, 2009 6:17 pm

Im beginning to think it might be the tires

Mike08Liberty · **Posted:** Wed Sep 23, 2009 6:38 pm

There's no way the tires can make it have that much body roll from how you're explaining it. Do you still have your stock wheels and tires? If so throw them back on and see how it drives.

I've been in truck with 8"+ lifts and 40"+ tires and they didn't even have a lot of body roll.

mabe your alignment is way off. did you realigned it since the lift

Elt31987 · **Posted:** Wed Sep 23, 2009 8:04 pm

Ya i put the lift on one saturday, the next saturday i had the alignment done then the saturday after that the tires were installed by the same place who did the alignment.
