Builders Series Double Adjustable Shocks

The Builders Series by JRi Shocks are available in both single adjustable and double adjustable configurations. The double adjustable version is more advanced and that allows you to adjust high speed and low speed independently with a sweeper-style adjuster and Ride Height adjustability via spring preload. This style of adjuster is better suited for the serious racer or casual driver that wants to adjust their car to any driving style. For more information on this adjuster style, picking the correct length, or mounting your Builders Series shock, see the links under the Tech Documents Tab.
