When the suspension compresses fully - whether from a heavy load, rough road, or towing - the bump stop absorbs the impact instead of letting the axle contact the frame directly. A worn or collapsed bump stop causes a loud clunking or banging noise at full suspension compression, excessive body roll, and potential frame damage over time. Key Features: - Genuine GM OEM - correct durometer for factory suspension tune - Fits 2WD and 4WD rear axle applications - Eliminates rear-end clunking and banging noise at full compression - Protects frame from axle impact during heavy loading or towing - Direct bolt-in replacement - no drilling or modification required Installation Notes: - Inspect bump stop mount for rust or corrosion before installation - Compare bump stop height to original - collapsed originals may look different - Thread size: M10x1.5 (metric bolt) - Positioning: ensure alignment tab\/nipple seats in the frame mount hole correctly Ships from Madison, NC. Genuine GM - backed by GM's warranty.\n\nVerify fitment using the eBay compatibility checker above or confirm with your VIN.\n\nShips fast from Madison, NC 27025."
