What Are JRi Builder Series Shocks?

Whether you are building a street car, drag car, or track car, you will need good suspension to put all that power to the ground and get good handling. One of the most important aspects of your suspension is the shock. While you can find specific spec shocks throughout the aftermarket marketplace, sometimes these shocks don't meet your specific needs. You will need a specific shock built for your application in these cases. At JRi shocks, we offer high-quality Builder Series shocks that offer you an off-the-shelf, performance-purpose shock.

What Are JRi Builder Series Shocks?

JRi’s Builder Series shocks are offered in single-adjustable and double-adjustable options, with the double-adjustable offering more advanced features. With a double adjustable builder series shock, you can adjust high speed rebound and low speed compression independently with a sweeper-style adjuster and Ride Height adjustability via spring preload. This type of adjuster is a great option for serious racers or casual drivers who want the ability to adjust their cars to a specific driving style.


The single and double-adjustable JRi builder series shocks are available in different strokes, extended, compressed, and recommended ride height lengths to get the perfect performance for your specific needs.
