Hyperco Bump Stop Spring Rate

Hyperco bump stop springs, also called bump springs or helper springs, are precision-wound steel coil springs for race car and performance suspensions. A bump spring works with the primary spring. The main spring can have a softer, more compliant initial rate, which lets the car settle to the ride height you want. The bump spring then adds its rate to hold a consistent dynamic ride height through the corner.

Key Features:

• Built for race and performance suspension setups, including oval track, road racing and off-road use
• Works in a nested arrangement with the main spring, so the rates add together
• More usable deflection and tight rate linearity for predictable, repeatable handling
• Precision-wound steel construction made to hold its free length and rate over long service life
• Available in a range of spring rates so you can tune the setup for your application
• Sold individually (each) by part number

Hyperco is known for the quality, durability and rate accuracy of its leaf and coil springs. Pick the child item with the spring rate you need to fine-tune your suspension.
