Construction & Design

Built with durability and performance in mind, the FOX Factory Series Rear Shock features a robust aluminum body and a high-pressure nitrogen gas charge to prevent cavitation and maintain consistent damping under extreme conditions. The internal bypass system allows fluid to flow through multiple circuits, providing a smooth transition between soft and firm damping stages. This design reduces shock fade and enhances control during both compression and rebound strokes.

Precision-machined components and premium seals ensure long service life and reliable operation, even in harsh off-road environments. The external reservoir increases fluid capacity and improves thermal management, allowing the shock to perform consistently during extended use.

Installation & Fitment

Installation of the FOX Factory Series Rear Shock Internal Bypass is straightforward, requiring no modifications to the vehicle’s suspension. This shock is a direct replacement for the rear shocks on Jeep Wrangler JK models from 2007 to 2018 with 3.8L and 3.6L V6 engines. Standard hand tools are sufficient for installation, and the process typically takes under an hour per shock.

For optimal performance, it is recommended to have the installation performed by a qualified technician or an experienced enthusiast familiar with Jeep suspension systems.
