The 18-position single adjustable valving allows simultaneous compression and rebound tuning from a soft, comfortable cruise setting to a firm, race-ready configuration -- making it easy to adapt the suspension from car-show cruising to autocross, road racing, or drag strip use without removing the shocks.\u003c\/p\u003e\u003cp\u003eThe fully threaded shock body provides up to 3 inches of threaded adjustment range for precise ride height tuning, with an overall lowering capability of 0 to 2 inches from stock height. The American-made high-travel springs feature fewer coils and a smaller wire diameter than conventional springs, resulting in increased suspension travel, reduced unsprung weight, and faster spring response for optimized handling. Each shock is 100% dyno tested and serialized for quality assurance, and is serviceable and rebuildable by QA1's factory or authorized service centers. Installation is a straightforward bolt-in process with no cutting or welding required. This kit is designed for vehicles with a recommended front-end weight of 1,901-2,000 lbs (typical of small block Chevy-equipped cars).
