Prothane 6-115 F-150 F-250 LD Body & Cab Mount Bushing Kit Standard Extended Crew Cab

The Prothane 6-115 polyurethane body and cab mount bushing kit is a direct-replacement upgrade for worn or deteriorated OEM rubber body mounts on Ford F-150 and F-250 LD trucks in standard, extended, and crew cab configurations. Over time, factory rubber body mount bushings compress, crack, and lose their ability to properly isolate the cab from the frame, resulting in sloppy handling, increased noise and vibration, and visible body sag or misalignment.

Prothane's polyurethane compound resists degradation from UV exposure, road grime, oils, and extreme temperatures — delivering a dramatically longer service life than the rubber bushings it replaces. The increased durometer of polyurethane reduces unwanted deflection between the body and frame, tightening up handling response for both street driving and off-road use.

Key Features:

• Polyurethane construction resists UV rays, ozone, oils, and road grime
• Reduces body-to-frame deflection for improved handling and steering feel
• Longer service life compared to OEM rubber body mounts
• Suitable for both street and off-road use
• Compatible with standard cab, extended cab, and crew cab body styles
• Direct OEM replacement — no cutting or modification required
• Backed by Prothane's lifetime warranty against defects in materials and workmanship

Available in red (standard Prothane color) or black. This kit provides everything needed to restore proper cab-to-frame alignment and eliminate the flex and noise associated with degraded rubber body mounts.
