1x QA1 GD507 Double Adjustable Front Coilover Shock

Product Description

The QA1 GD507 is a double-adjustable front coilover shock built for full-size GM owners upgrading from stock struts to a tunable coilover setup. Independent 18-position compression and rebound adjustment lets you dial in handling separately from ride comfort, while the threaded body gives up to 2 inches of ride-height adjustment for dialing in stance without cutting springs or adding drop spindles.

Because this is a shock-only part number, it needs to be paired with QA1's tapered Pro Coil springs to complete the coilover - it isn't a bolt-in-and-done kit on its own. It bolts up to either factory stamped-steel control arms or QA1's tubular arms, making it a flexible option whether you're keeping the stock front end or building it out further.
