Shock absorbers come in all shapes and sizes, but for the most part, they work the same way. During compression and rebound, the main piston forces oil through ports on both sides. This oil flow is regulated by stacked valve disks—arranged in a pyramid shape—that determine how quickly or slowly oil passes through. The piston design and valving have a major impact on ride quality, and if the shocks aren’t tuned properly, the suspension can feel too stiff or too soft.

With today’s off-road builds getting bigger, heavier, and more capable, it’s more important than ever to have shocks custom tuned to match your vehicle’s weight and driving style. That’s why AccuTune Offroad specializes in custom valving for Fox, King, and Ride Shocks. Using our proprietary AccuTune Equations, customer feedback, and years of tuning experience, we deliver precision valving that transforms ride quality—whether you’re cruising fire roads, tackling rocky trails, or loading up for an overland adventure.
