Construction & Design

Installation is straightforward and requires no special modifications or additional components. These shocks bolt directly into the factory mounting points, allowing for a hassle-free upgrade that restores and enhances suspension performance on lifted vehicles.

For best results, it is recommended that installation be performed by a qualified technician or an experienced enthusiast familiar with Jeep suspension systems. Proper installation ensures optimal shock function and vehicle handling characteristics.
