If you have a larger wheel and tire combination compared to stock, it is absolutely essential to toughen up your TJ or LJ build. Maximize your power and torque to allow your TJ or LJ to tackle trails the way it once did to back in the day.

Exhaust upgrades willoffer even more performance benefits with the added bonus of transforming your exhaust sounds to be deeper and more aggressive.

They make reinflating your Jeep's tires after a trail run a much more efficient and stress-free task.
