Frequently Asked Questions
What does a track bar correction kit do?
When you lift your vehicle, the factory track bar angle changes, pulling the rear axle to one side. The B.O.T.C.K. corrects that angle, recentering the axle and restoring proper geometry — eliminating that off-center steering feel and uneven tire wear.
Why 7075 billet aluminum?
7075 is an aerospace-grade aluminum alloy significantly stronger than the more common 6061. It gives you the weight savings of aluminum with the strength needed to handle real off-road abuse without bending or failing.
Do I need to weld anything?
No. Every B.O.T.C.K. kit is a true bolt-on install. If you can use basic hand tools, you can install this yourself in your driveway.
What lift height does this work with?
The B.O.T.C.K. is designed for lifted vehicles. Check the individual product page for your specific vehicle and lift range to confirm fitment before ordering.
