Description

These kits are built for Jeep people who actually use their Jeeps. If you’ve got a YJ with a 4.0L and you're running lockers, big tires, or just hitting the trail hard, PSC’s Cylinder Assist Steering Kits are exactly what you need to keep control when things get gnarly.

We offer two versions—SK230 with a 6" stroke and SK231 with an 8" stroke—so you can match your setup and suspension travel. Both kits are trail-proven, bolt-on (with some welding for the ram mount), and built to handle real off-road abuse.
