    Hi guys. I'm in the process of bagging my truck (4 link) would running the URD trac bar be an issue? I've seen you have to relocate the charcoal canister?

    Pros and cons?

    Anyone have a bagged xrunner with a trac bar?

    There has been a few bagged trucks, but I do not remember if anyone had a trac bar.

    The charcoal canister move was prompted when you did a DJM drop. I am sure you will have to do this as well.

    The URD trac bar is used to mitigate the axle wrap of leaf springs. The design of it is basically like a single ladder bar. If you four link the rear for the air bags, you'll have the motion of the axle wanting to do two different things. The trac bar wants to pivot with the suspension, while the 4 links will try to move the axle in a parallel motion. The good news is that if you four link, you will not need the trac bar.

    If I remember correctly, markgt531 has the spring packs removed except for the main leaf and uses bags to compensate for the sag of the single leaf. In this case, the URD trac bar still works as designed. Also, because there is only one leaf used, there is even more of a reason for the trac bat to mitigate axle wrap.

    YEP! very true, i did not fully understood axle wrap/wheel hop. when we bagged the rear and removed 2 of the leafs there was very obvious axle wrap even when i try n do a weak ass peel out (wouldnt dare do burnout with 1 leaf spring). Only time it didnt axle wrap itself is when pavement are wet (duh lol ). My 2nd Xrunner is where i can slightly understand more about axle wraps. my 2nd one 06 swb(stock) did not have axle wraps

    but back to URD TRAC BAR.... yes very well worth it. best bang for ur buck! cant go wrong. i looked into caltracs they are nice but since im lowered theres a possibility that itll hit so i opt for URD since its nicely snug and have lots of clearance

    cons: if purchasing used, make sure all the hardware/bolts are included ESP the extended botls for the diff.
    pros: SOLID SOLID SOLID!! ull feel more confident and not worry about axle wrap or anything that may be damaged as a result of it
