99-06 GM P/U 2/4WD Body Mounts

The 99-06 GM P/U 2/4WD Body Mounts are essential replacement components for aging factory rubber bushings specifically designed for Chevrolet Silverado and GMC Sierra trucks. Over time, original equipment mounts deteriorate due to exposure to road salt, oil, and ozone, leading to cab sag and excessive vibration. This Prothane kit provides a permanent solution for owners looking to restore proper body-to-frame alignment and structural integrity.

Engineered from high-quality polyurethane, these bushings offer significantly higher resistance to compression and chemical degradation than standard rubber alternatives. The precision-molded design aims to improve overall handling and chassis feedback while addressing the mushy feel associated with worn-out mounts. Because polyurethane does not rot or crack like organic rubber, these mounts provide a consistent spring rate that enhances driving performance.

This kit is ideal for those performing a frame-off restoration or simply tightening up a daily driver, ensuring the cabin remains securely anchored under all driving conditions. The black finish provides a clean, factory-like appearance that integrates seamlessly with the undercarriage of any full-size GM pickup. Designed specifically for 1999-2006 GM full-size pickups, it covers both two-wheel drive and four-wheel drive configurations.
