Prothane 7-121-BL Polyurethane Body Mount Bushing Kit Black - 1965-1967 GM Hardtop

The Prothane 7-121-BL is a polyurethane body mount bushing kit engineered specifically for 1965–1967 GM A-Body hardtop models, including the Chevrolet Chevelle, El Camino, and Malibu. Replacing deteriorated OEM rubber body mounts with this precision-fit polyurethane kit is one of the most cost-effective upgrades available for improving chassis rigidity and driving feel on classic GM vehicles.

Factory rubber body mounts degrade over time due to constant stress, UV exposure, and road grime. Once they begin to fail, the connection between the body and frame is compromised — resulting in unwanted flex, excessive noise, and a degraded driving experience. Prothane's polyurethane construction is significantly more durable than OEM rubber and is not vulnerable to the environmental factors that cause rubber to crack and deteriorate.

Key Features:

• Black polyurethane construction — graphite-infused to help minimize squeaking
• Engineered to provide superior rigidity over OEM rubber while maintaining ride compliance
• Resistant to road grime, oils, UV rays, and weathering
• Specific fitment for 1965–1967 GM A-Body hardtop body style
• Hardware not included — reuse original hardware or source from a local supplier
• Backed by Prothane's lifetime warranty against defects in materials and workmanship

Prothane's black polyurethane bushings share the same durometer (hardness) as their red counterparts — the graphite additive in the black compound offers the added benefit of noise reduction. This kit is suitable for both street driving and off-road use, delivering long-lasting performance that outlasts factory rubber components.
