We reached out to an independent third party to test our product vs our competitors to fully understand how they all stack up, using industry leading test hardware to study their dynamic, variable rate nature.

A high-speed, Fixed-displacement test was performed to study 4 key bump stop performance metrics. 

Midwest Suspension Co, professionals in the suspension industry performed this testing on their suspension dyno.

All products tested are designed and sold for the same vehicle applications.

  1. Damping - Energy dissipation (damping) is vital for moderating the energy from off road impacts, contributing to a smoother, more controlled ride. Perry Parts bump stops dramatically outperformed the competition, registering up to 4x more damping than other bump stops tested.

  2. Progressive Spring Rate - Progressive spring rate on a bump stop provide variable resistance, enhancing comfort during small bumps while offering increase support during large impacts, improving control and safety. With Perry Parts unique additive manufacturing process, our bump stops achieved an effective progressive spring rate, while maintaining the most consistent rebound velocity.

  3. Early Engagement - A bump stop that engages too early can unnecessarily stiffen the suspension, compromising ride comfort and handling. If the bump stop engages too late, it risks allowing the suspension to bottom out, leading to potential damage and reduced control. Perry Parts and DuroBumps bump stops achieved what we believe is the "goldilocks" engagement zone, engaging at just the right time. Not too early. Not too late.

  4. Suspension Protection - An insufficient bump stop can lead to suspension damage by failing to adequately absorb impacts, allowing the suspension to bottom out and subjecting components to excessive stress and strain. Perry Parts and Super Bumps offered the best protection, followed closely by DuroBumps, then Energy, Timbren, and finally SumoSprings.
