Fox Racing Shocks 981-35-402-L Factory Race 3.5 x 16 External Bypass 5-Tube 3/4" Piggyback Shock Left

The Fox Racing Shocks 981-35-402-L is a Factory Race Series 3.5-inch external bypass piggyback shock featuring 16 inches of travel, a 5-tube bypass configuration with 3/4-inch bypass tubes, and a left-hand orientation. Built for serious off-road performance, this shock delivers position-sensitive, externally adjustable damping backed by decades of proven race success.

The 3.5-inch steel body features a dual-coat finish — a zinc-plated basecoat topped with Fox's proprietary Grey Cerakote® ceramic coating — for outstanding corrosion resistance and long-term durability in harsh environments. The integrated piggyback reservoir is secured with a black anodized billet aluminum clamp, and the body cap rotates to allow easy positioning of the tubes and reservoir to clear obstacles during installation.

Key Features:

• Gen 3 External Bypass Clicker Adjusters — Provides 25% greater adjustment range over the previous generation with fewer parts for improved serviceability; black anodized adjuster housings feature color-coded seals for compression, rebound, and gold valves
• 5-Tube External Bypass Design — Position-sensitive damping allows oil to flow around the piston at specific points of the stroke, delivering a progressive damping curve that eliminates harshness over whoops while maintaining high-speed control
• Dual Speed Compression (DSC) Adjustment — Tool-free high- and low-speed compression tuning for fine-tuning to weight, terrain, and speed
• 17-4 H900 Stainless Steel Piston Rod — Exceptional hardness and chip resistance, addressing the most common cause of shock seal failure in off-road use
• Viton Seals — Premium low-friction, low-wear, high-temperature sealing material proven in off-road racing applications
• PTFE-Lined Heat-Treated Alloy Steel Spherical Bearings — Ensures quiet, smooth shock movement at both eyelets
• Redundant Sealing Pack — Main seal, wiper seal, and scraper seal for consistent leak-free performance in extreme conditions
• Black-Anodized CNC-Machined 6061-T6 Billet Aluminum Components — Lightweight, precision-machined hardware throughout
• Rotating Body Cap Design — Simplifies installation and reservoir positioning without specialized tools
• Rebuildable and Serviceable — Fully user-serviceable with custom valving options available
