Fox Racing Shocks jksJSPEC147PES JSPEC Performance Elite Series Shock Absorber

The Fox Racing Shocks jksJSPEC147PES is a JSPEC Performance Elite Series (PES) shock absorber developed in collaboration between JKS Manufacturing and Fox Racing Shocks. This shock is purpose-built to complement JKS suspension lift systems, with custom valving engineered specifically for lifted Jeep applications running larger-than-stock wheels and tires.

Key Features:

• Performance Elite Series (PES) construction featuring a 2.5-inch aluminum shock body for superior heat dissipation and durability
• Custom JKS-specific valving tuned by the JKS R&D team to account for the increased unsprung weight of larger aftermarket wheels and tires
• Remote reservoir design for extended oil capacity and fade-resistant performance during prolonged off-road use
• External bypass or position-sensitive damping (PES-grade) for a balanced blend of on-road comfort and off-road control
• Made in the USA by Fox Racing Shocks to exacting quality standards
• Direct bolt-on fitment when used as part of a matched JKS suspension system
• Designed to work in conjunction with JKS dual-rate coil springs for maximum performance synergy

JKS rigorously tests its shock valving to deliver a controlled, comfortable ride on road while maintaining serious capability on the trail. The PES designation represents Fox's Performance Elite tier — a significant step up from standard Performance Series shocks — offering adjustability and damping refinement suited for enthusiasts who demand the most from their suspension setup. This shock is sold individually.
