FOX Extends Dual Speed Compression (DSC) Adjuster to its Truck and Offroad Product Lineup

FOX Dual Speed Compression (DSC) Adjuster

El Cajon, Calif. – FOX recently made its Dual Speed Compression (DSC) adjuster available for trucks, Jeeps, and off-road vehicles. The addition of DSC in a truck shock application provides added control and comfort tuning for on-road use while also offering more aggressive damping for use off-road. The adjuster allows for precise suspension tuning with the simple twist of two clearly defined knobs: No tools and no mess, just a way to easily fine-tune your suspension to best suit your needs in any conditions.

With DSC, you can adjust the shock’s low-speed and high-speed compression damping by simply turning the external adjuster knobs. The billet 6061-T6 anodized aluminum knobs increases both low and high-speed levels by 25%, allowing you to maximize small bump compliance and traction while still having the extra damping required for big hits.

The DSC’s gold low-speed compression (LSC) adjuster knob offers 10 clicks of adjustment and primarily affects compression damping during slow suspension movements such as G-outs or smooth jump landings. It also affects wheel traction and the harshness or plushness of the vehicle’s ride. The DSC’s blue high-speed compression (HSC) adjuster knob offers 12 clicks of adjustment and mainly affects compression damping during medium to fast suspension movements such as steep jump faces, harsh flat landings, and aggressive wash board roads.

The DSC is mated to a large 2.5-inch 6061-T8 aluminum external reservoir that dissipates heat faster than the previous steel reservoir, providing precise control no matter how hard you push your shocks. The aluminum reservoir is anodized black and provides the shock with an increase in oil and nitrogen capacity. Capping off the reservoir is an integrated O-ring sealed cover for the FOX Air Valve (FAV). The new capping system provides an increased level of safety to ensure the valve is not damaged or discharged while battling the elements of off-road driving.

Available applications of the new DSC adjuster include the 3.0 Factory Series Coil-over Internal Bypass Adjustable for Ford SVT Raptor and 2.5 Factory Series Internal Bypass Adjustable Reservoir smooth body shocks for Jeep Wrangler JKs, as well as all 2.5 Factory Series Coil-over Adjustable Reservoir shocks. The DSC adjusters are also available as an upgrade for any existing 2.5-inch diameter smooth body or coil-over reservoir shock with a 7/8-inch shaft.
