Description

The PSC Motorsports SK689R64JP1 Big Bore XD Cylinder Assist Steering Kit is designed for the 2021-2026 Jeep Wrangler JL Rubicon 392 HEMI with an aftermarket front axle. This kit upgrades the factory steering system to handle increased torque loads from larger tires and aftermarket axle assemblies, resolving poor factory steering performance and eliminating issues like excessive on-center play and electro-hydraulic pump overheating.
