Prothane 7-105-BL GM Body Mount Bushing Kit for Blazer Black - K10 1967-1972

Prothane's 7-105-BL Body Mount Bushing Kit is a direct replacement for worn or deteriorated OEM rubber body mounts on 1967–1972 GM K10 Blazer trucks. Over time, factory rubber bushings compress, crack, and lose their ability to properly isolate the body from the frame — resulting in increased noise, vibration, and harshness (NVH) as well as reduced handling precision. This kit restores the correct geometry and feel of your cab-to-frame interface.

Engineered from Prothane's proprietary black polyurethane compound, these bushings deliver significantly greater durability and rigidity than OEM rubber while still providing enough flex and compliance to keep ride quality smooth and cabin noise to a minimum. Polyurethane resists deterioration from oil, grease, road salt, and extreme temperatures — making this kit equally at home on the trail or the street.

Key Features:

• Made from high-quality black polyurethane for superior durability over OEM rubber
• Resists compression set, oil, and environmental degradation
• Improves body-to-frame rigidity for better handling response
• Maintains sufficient resilience to reduce noise, vibration, and harshness
• Suitable for both off-road and street driving applications
• Direct OEM replacement — no cutting or modification required
• Complete kit includes all necessary bushings for a full body mount replacement

Prothane part number 7-105-BL is a cost-effective upgrade that improves the feel and longevity of your classic GM truck's body mount system. Installation is straightforward for the experienced DIYer and is a recommended service item during any frame-up restoration or suspension refresh.
