Area 51 Suspension Foam Style Bump Stop — 2" OD

Area 51 Suspension's Foam Style Bump Stops — open-cell urethane foam pucks that compress progressively and recover quickly. Foam bumps give a softer, more gradual initial engagement than solid urethane pucks, making them the go-to choice for late model LR and RR positions where you want progressive contact rather than a hard stop.

• 2.0" OD × 5/8" ID — fits standard 16mm shock rod
• Heights: 1/2", 3/4", 1"
• Four durometers: 35 (Soft/Red) through 75 (Hard/Black)
• Open-cell urethane foam — progressive compression, fast recovery
• Color-coded for fast trackside ID
• Stack multiples to tune travel and engagement point

Durometer color guide: 35 Soft (Red) · 50 Medium (White) · 65 Firm (Blue) · 75 Hard (Black)

Puck vs. foam? Foam gives a more progressive, gentler hit. Pucks give a firmer, more defined stop. Not sure which to run? Contact us.
