Product Description

The Prothane 6-105 polyurethane body mount bushing kit provides a comprehensive upgrade for 1966-1979 Ford F-Series 4WD trucks experiencing deteriorated or worn original rubber body mounts. Body mounts secure the truck's cab and bed to the frame while isolating road vibrations from the passenger compartment. Factory rubber mounts deteriorate from stress, UV exposure, and temperature extremes, eventually cracking or disintegrating. When body mounts fail, the body-to-frame connection becomes compromised, leading to excessive movement, misaligned doors and panels, increased cabin noise, and rough ride quality.

Engineered from premium-grade red polyurethane rather than conventional rubber, the Prothane 6-105 delivers superior durability while maintaining appropriate compliance for daily driving. Polyurethane resists breakdown from petroleum products, ozone, and weathering that destroys rubber components. Each bushing is precision-molded to exact OEM specifications, ensuring perfect alignment with factory mounting holes and proper load distribution across all twelve body mount locations.

Installation requires removal of the truck body from the frame to access all twelve mounting locations, making this ideal during frame restoration or engine removal projects. This kit includes only the polyurethane bushings and does not include mounting hardware such as bolts, washers, or steel sleeves, which must be reused or purchased separately. Part number 6-105 is specifically for 4WD models--2WD applications require part number 6-110. Backed by Prothane's lifetime warranty, these USA
