Prothane 7-145-BL Polyurethane Body Mount Bushing Kit Black - Convertible

The Prothane 7-145-BL is a polyurethane body mount bushing kit engineered specifically for 1959–1964 Chevrolet Bel Air, Biscayne, Caprice, and Impala convertible models. Replacing deteriorated OEM rubber mounts with Prothane's polyurethane bushings restores the critical body-to-frame connection, improving steering feel, handling response, and overall chassis rigidity.

Factory rubber body mounts break down over time from heat cycles, UV exposure, and road grime. Once they fail, the body-to-frame attachment is compromised—leading to excessive flex, unwanted noise, and a degraded driving experience. Prothane's polyurethane compound resists all of these elements, delivering long-lasting performance that OE rubber simply cannot match.

Key Features:

• Made from high-durometer polyurethane — more rigid and durable than OE rubber
• Resistant to UV rays, road grime, oil, and environmental wear
• Black color variant with graphite blend for reduced noise and friction
• Compression-style body mounts — no lubrication required at installation
• Convertible-specific design — engineered for the unique mount configuration of open-top body styles
• Backed by Prothane's lifetime warranty against defects in materials and workmanship

The -BL suffix designates this kit in black. Both the black and red Prothane variants are manufactured to the same hardness specification and will perform identically over the life of the vehicle. This kit is a direct, cost-effective upgrade for restoring structural integrity and driving feel to classic full-size GM convertibles.
