Bump Springs are used in conjunction with a primary spring to allow a race car to have a relatively soft / compliant initial spring rate to get down to the desired optimum ride height and then pick up the rate of the bump spring to achieve a constant / optimum dynamic ride height.
Key Benefits of Bump Springs
- More usable deflection
- 2% rate linearity tolerance from 20% to 60% of deflection
- 4% rate linearity tolerance from 61% to 80% of deflection
- Designed to fit standard hardware
- Maintain free length and rate throughout a near infinite operational life
