Description

The PSC Motorsports SK689R64JP1-6.75W-NC Big Bore XD Cylinder Assist Steering Kit is designed to upgrade the steering system of the Jeep Wrangler JL, replacing the factory EHPS with a PSC Big Bore XD-JL Steering Gearbox and a belt-driven High Flow Mechanical Power Steering Pump. This kit significantly improves steering performance, especially in off-road conditions with locking differentials. It requires a minimum of 7 degrees positive caster and may necessitate the use of a Tazer JL Programmer to override OEM EHPS functions. Compatibility considerations include potential interference with certain aftermarket track bars and a recommendation for vehicles with up to 35-inch tires. This kit is a comprehensive solution for enhancing steering feel and capability.
