Adding King Compression adjusters to your non adjuster shocks will give you quick tuning ability without having to completely revalve the shock. Adding adjusters starts at $375 per shock. The price includes parts and installation. Since Kings are valved differently for non adjuster and adjuster series, the labor to revalve the shock properly will be included. Take note of how your vehicle rides, how you use it, and how much weight you are running and we can recommend custom valving for your setup and needs.
