Description
If you’re building a front suspension that demands precision tuning and consistent performance, a quality coil spring is non-negotiable. The Hyperco 18Y0525 delivers a stiff 525 lb/in rate in a compact 5-inch diameter package, making it ideal for vehicles where space constraints or aggressive geometry requires a shorter spring. Whether you’re dialing in street-strip suspension or fine-tuning a dedicated race car, this conventionally-wound spring provides the predictable, linear rate you need for repeatable lap times.
