Product Resources
Features & Product Details
This kit is the perfect solution for the daily driver JL project with cylinder assist plans for the future. Install the core components now, add the cylinder assist components later! PSC has taken the Jeep JL steering system back to the drawing board and engineered our exclusive Big Bore XD-JL Steering Gearbox and a traditional belt-driven High Flow Mechanical Power Steering Pump Conversion, producing an essential upgrade to solve the undesireable factory steering performance while able to efficiently handle the increased torque loads due to larger tire sizes and installing aftermarket axle assemblies.

Overall I’m very happy with this system. On the trail it’s one of the best upgrades I’ve ever made. I can steer my aired down 37’s with one finger. It’s way more stable than the stock system, this should really be a factory option. The install isn’t too difficult, but the instructions could be better. Watch Bleepin’ Jeep’s YouTube video and you’ll do just fine. Bleeding the system is very time consuming, but PSC doesn’t hide that fact. If you have aftermarket steering components you’ll need to find a way to mount the ram to the axle. On the road, wandering and constant wheel adjustments are a thing of the past. It is more sensitive to input, but 100 times better than the stock setup. I highly recommend this kit if you do a lot of wheeling, especially rock crawling. It’s an expensive kit, but definitely worth it after seeing how much more enjoyable steering on the trail becomes!
