QA1’s Proma Star single-adjustable coilover shocks are a versatile solution for custom suspension setups where a direct-fit coilover isn’t available. Ride height can be easily dialed in using the threaded body and included spring hardware, making it simple to set the stance on hot rods, street machines, and custom chassis builds. The 18-position adjustable valving lets you fine-tune ride quality on the fly—from a smooth street feel to a firmer, more controlled response. Designed for use with 2.5" I.D. coil springs, these shocks offer reliable performance and smooth operation for a wide range of builds.
