Description
Description
Replace cracked, deteriorated, or missing front suspension bump stops with this Genuine GM 20781438 Front Bump Stop / Jounce Bumper.
Over time, repeated suspension contact can cause the factory rubber bump stops to crack and deteriorate. Once damaged, they may no longer properly cushion suspension travel, resulting in harsher contact when the suspension compresses over large bumps.
This is a Genuine GM replacement part designed for proper factory fitment on 2011–2026 Chevrolet Silverado and GMC Sierra 2500HD/3500HD trucks.

- Genuine GM OEM replacement
- Replaces worn or cracked front bump stops
- Helps cushion suspension travel during compression
- Restores factory-style fit and function
