What does "double adjustable" mean?

Double-adjustable shocks allow you to independently control the rebound and compression damping. This gives you a wider range of tuning options compared to single-adjustable or non-adjustable shocks. You can dial in the ride for street, track, or off-road use.

What spring rate should I choose?

Spring rate is determined by vehicle weight, suspension type, and intended use. A lighter car or softer setup will use a lower spring rate. QA1 can help you determine the best spring rate for your application.

Do these coil-overs come with a warranty?

QA1 offers a limited lifetime warranty on their shocks. This covers defects in materials and workmanship. Be sure to register your purchase with QA1 to activate the warranty.
