FOX 981-20-102 2.0" 6.5" Emulsion Coil-Over Shock for Off-Road Builds

Vehicle Fitment

• Universal / custom-fit coil-over shock - suitable for lifted trucks, off-road vehicles, prerunners, rock crawlers, and custom suspension builds requiring 6.5" travel. Proper spring selection and mount geometry required.

Features

• 2.0" smooth-bore steel body with clear-zinc plating for durability and corrosion resistance
• 5/8" chromoly steel shock shaft (hard-chrome plated) for strength and long-term durability under heavy load or rough terrain
• Emulsion-type coil-over shock design - compact body without remote reservoir, suitable for tighter suspension setups
• Owner-serviceable and rebuildable construction - allows maintenance, seal replacement, or re-valving as needed
• High-flow internal valving tuned for off-road / mixed-terrain performance - balances comfort, control and responsiveness over bumps, ruts or uneven surfaces
• Coil-over coil spring seat with preload adjustability (springs sold separately) - allows customization of ride stiffness, sag and load handling
• Compact eyelet top and bottom mounts - compatible with many custom suspension frames or aftermarket mounting kits
• Moderate 6.5" travel - offers improved suspension compliance over stock or short-stroke shocks without excessive length or full-travel bulkiness

Product Description

The FOX 981-20-102 coil-over shock delivers a balanced mix of durability, control, and tunability for off-road builds, lifted trucks, prerunners, and custom suspension setups that require moderate travel and a compact footprint. With a robust 2.0" steel body and a 5/8" chromoly shaft, this shock is built to withstand rugged terrain and repeated stress under load - while the emulsion design keeps things compact for tight wheel wells or custom mounts. The internal high-flow valving balances damping for rough terrain control and comfort, offering better compliance than many stock or static shocks.

Because this is a universal coil-over, proper installation requires selecting appropriate coil springs (based on vehicle weight and intended use), verifying eye-to-eye mount spacing, and adjusting spring preload to match ride height, load, and intended terrain. Once properly set up, the 981-20-102 provides a durable, serviceable suspension solution - ideal for off-road enthusiasts and builders who want a flexible, tuneable shock for rocks, trails, lifted builds, or mixed-terrain driving.
