Description

This kit replaces the Jeep Wrangler JL's factory electro-hydraulic steering (EHPS) system with PSC's Big Bore XD-JL Steering Gearbox and a belt-driven High Flow Mechanical Power Steering Pump Conversion. It improves steering performance, especially when handling larger tires and aftermarket axles. Designed for Jeeps with locking differentials, aftermarket axles, and tires up to 35 inches, it supports both daily driving and off-road use, enhancing turning capability when differentials are engaged. The larger gearbox may limit the use of some aftermarket track bars.
