Prothane 7-131 Polyurethane Body Mount Bushing Kit 2-Door Hardtop

The Prothane 7-131 is a complete polyurethane body mount bushing kit specifically designed for 1955–1957 Chevrolet Bel Air, Biscayne, Caprice, and Impala 2-Door Hardtop models. Replacing aged and deteriorated OEM rubber body mounts is one of the most cost-effective upgrades you can make to restore and improve the handling, responsiveness, and overall feel of your classic GM full-size.

Prothane's high-performance polyurethane compound delivers significantly greater structural rigidity than factory rubber bushings while retaining enough flex and resilience to keep noise, vibration, and harshness (NVH) levels in check on both the street and off-road. Unlike rubber, polyurethane resists compression set, cracking, and deterioration from oil, road chemicals, and UV exposure—making these mounts a long-lasting upgrade built to outlast OEM replacements.

Key Features:

• Engineered specifically for 1955–1957 Chevy Bel Air, Biscayne, Caprice & Impala — 2-Door Hardtop body style only
• High-performance polyurethane construction outperforms OEM rubber in rigidity, durability, and longevity
• Resists deterioration from oil, grease, road chemicals, and UV exposure
• Reduces body flex for sharper handling and improved steering feel

Whether you're building a driver-quality resto, a show car, or a weekend cruiser, the Prothane 7-131 body mount kit is a proven foundation upgrade that restores structural integrity and improves the driving experience of your classic tri-five Chevrolet.
