Swift Springs Introduces a New 2.5" Linear Round Wire Bump Spring

At Swift Springs, innovation starts by listening to racers. We're excited to introduce the newest addition to our growing Bump Spring lineup—the SBS0550 LH, a 550 lb/in Linear Round Wire Bump Spring designed to deliver the durability, consistency, and performance today's racers demand.

Built with a 2-inch outer diameter and 2.5-inch free length, this new bump spring provides 1.25 inches of available stroke, making it an excellent option for racers looking for precise suspension control in demanding racing conditions.

Designed from Racer Feedback

The SBS0550 LH wasn't created by chance—it was developed because racers asked for it.

After receiving requests from teams looking for a larger bump spring option with a 550-pound rate, our engineering team went to work. The result is a spring that combines the proven consistency of Swift Springs with the durability racers rely on every weekend.

Manufactured using Swift Springs' proprietary HS5.TW material, this new bump spring is engineered to provide linear performance throughout its usable stroke while maintaining the quality standards that have made Swift Springs a trusted name in motorsports.
