This high-performance, full-length adjustable coilover kit is designed to optimize vehicle handling dynamics by replacing standard factory shock absorbers and coil springs. The kit features heavy-duty threaded steel or aluminum monotube damper bodies paired with linear-rate lowering springs, aluminum upper top mounts, and dual locking rings for independent ride height adjustment. This setup allows enthusiasts to precisely lower their vehicle’s ride height, adjust spring preload, and fine-tune damping stiffness (often featuring 16 to 32 stages of rebound adjustment) to eliminate body roll for spirited street or competitive track driving. It’s specifically structured as a full 4-piece set in its original factory distribution box with protective plastic packaging and separating cardboard partitions.
