Product Details

The Bilstein B6 4600 line is engineered for drivers who want a firmer, more controlled response than worn OE shock absorbers can provide. For front suspension use on Jeep Grand Wagoneer, Jeep J10, Jeep J20, Jeep Cherokee, and Jeep Wagoneer models, B46-0046 uses a monotube layout that helps maintain consistent damping under repeated suspension movement. The application-specific valving is matched to the vehicle platform to support predictable ride behavior on pavement and uneven roads.

This part cross-references Rancho RS999113 for the same application.

Installation Notes and Tips

Confirm front-position fitment before ordering and match the upper and lower eye mounts to the vehicle’s suspension hardware. Inspect related bushings, mounts, and fasteners during replacement so the new shock absorber can operate correctly. For best results, replace shocks in pairs on the same axle and verify that the suspension remains at stock height.
