Rear Track Bar

I was looking at my rear track bar now that I finally got it down off the lift and it seems to be really close to my exhaust. I have a 4.5" BDS lift kit with a raised T/B bracket, I was wondering if getting a longer adjustable T/B and mounting it to the lower stock height would cause any problems???

Thanks,
Sean

Yes, you will be lowering your rear roll center. The "problems" will be in handling while cornering and under acceleration, even more so with that V8 you've got crammed under the hood.

The further the roll center is from the center of gravity, the more body roll in corners. The more body roll, the more axle steer with short arms.

Also, the further the roll center from the CG, the more you will torque the body under accel. The the amount of torque you have with your engine you would be able to steer the jeep with the throttle alone.

Any ideas?? It's a brand new AFE exhaust made for the Jeep, I don't really want to start cutting it up, I guess I might have to. Would lowering the body mount an equal distance have the same effect?

Thanks for the replies,
Sean

I don't have the rear section welded yet, I'm gonna see if I can rotate it up a little more. Kind of the obvious answer I guess.

No, don't drop the frame bracket. The roll center is the theoretical point that is the average height from the ground of the trackbar brackets. Rasing the axle bracket raises the roll center. Lowering the frame lowers it. both will get the trackbar flatter (which is good) but is only half the equation.

Depending on your bumpstops you may be ok, or just do a pre-axle dump.

Flex it out and see how much it hits before you freak out too much.

flex it out as Goody said, you can always mess with your bump stops too to prevent contact.

Also, cant really tell from the pictures, but the exhaust looks like it's sectional, could you splice in a short straight piece and raise the arch of the tail pipe up higher for more clearance?

Thanks for the input. I already freaked out a bit though, kinda funny you could tell. I'm finally finishing up my build and never noticed that until yesterday when it was finally off the lift. I see Metalcloak has just what I need but I'll flex it out and see what it looks like.

Thanks
Sean
