Bump Stops
Bump stops control the last part of suspension travel, keeping the shock from bottoming out and affecting how the car settles once load comes off. IBRP stocks AFCO and Integra bump stops in rubber, puck and roller styles.
Rubber shock bumpers (soft, medium) give progressive take-up. Puck style stops are graded by durometer, from 50D to 60D, so rate can be set deliberately, and are colour coded for quick identification in the pits. Roller bump stops suit setups needing consistent behaviour under sustained load. Packers and spacers let you adjust the gap between heats without buying new parts.
Choice depends on your class, shock and track surface, for example a tight banked circuit versus a rough dry-slick track.
Frequently asked questions
What's the difference between rubber, puck and roller bump stops?
Rubber shock bumpers give a progressive, softer take-up and come in soft or medium compounds. Puck bump stops are graded by durometer (50D to 60D) so you can set a specific rate. Roller bump stops are designed for consistent, repeatable behaviour under sustained load.
How do I choose the right bump stop durometer?
It depends on the class you run, the shock it's fitted to, and the track surface. A tight, heavily banked circuit needs a different setup to a rough, dry-slick track, so match durometer to how much travel you need to control.
What are bump stop packers for?
Packers and spacers adjust the gap before the bump stop engages, changing how much suspension travel is available. It's a quick, low cost way to alter how the car uses its travel between heats.
