Factory rubber body mounts on the 2003-2007 Ford Super Duty were engineered for cost, not longevity. After years of heat cycling, towing loads, and road salt exposure, those mounts compress, dry-rot, and crack, letting the cab sag out of alignment with the bed and feeding chassis vibration directly into the radiator, hoses, and surrounding cooling components. Mishimoto's silicone body mount set replaces the entire eight-bushing array with a direct-fit kit designed to restore ride height, pull body lines back into alignment, and absorb the noise, vibration, and harshness the factory rubber no longer contains.
Silicone that holds up where rubber and urethane fail. Each bushing is molded from premium silicone that retains its resilience for the life of the truck. Unlike factory rubber, it does not harden, dry-rot, or split after a decade of heat cycles. Unlike aftermarket urethane, it does not develop the dry squeak that makes every low-speed maneuver audible from twenty feet away.
Dual-coated steel cups and Dacromet hardware resist corrosion from the inside out. The steel sleeve carrying every bushing carries two layers of corrosion protection, blocking the rust-through failure that turns a routine mount swap into a full body-off repair. Every bolt, nut, and washer in the included hardware kit ships finished in Dacromet for the same long-term protection against road salt and trail conditions.
A keyed cap anti-rotation design turns a two-person job into one. The cup retainer holds both the upper and lower cups in position while you insert the bolt and torque from above. No second set of hands, no wrench-on-wrench gymnastics underneath the truck.
Protects components well beyond the cab. Worn body mounts transmit chassis vibration directly into the radiator, coolant hoses, and the surrounding cooling stack, accelerating wear on parts that have nothing to do with the mounts themselves. Silicone absorbs NVH at the source, shielding those components from the stress that degraded rubber lets through.
Product Benefits
- Silicone Construction: Retains resilience through heat cycles without hardening, cracking, or developing the squeak common to urethane alternatives.
- Restores Cab Alignment: Replaces compressed, dry-rotted mounts to bring ride height and body-to-bed alignment back to spec.
- Dual-Coated Steel Cups: Two layers of corrosion protection on every bushing sleeve prevent the rust-through failure that complicates future mount work.
- Complete Dacromet Hardware Kit: Every fastener needed for the install ships in the box, finished for long-term resistance to road salt and moisture.
- Keyed Cap Anti-Rotation Design: Cup retainer holds upper and lower cups in place during installation so one person can bolt and torque from above.
- NVH Absorption: Silicone isolates chassis vibration from the cab and surrounding components, including the radiator, hoses, and cooling stack.
- Direct Fit: Eight bushings sized for OEM Crew Cab mount points with no drilling, cutting, or modification required.
- Mishimoto Lifetime Warranty: Every bushing and component in the kit is backed for the life of the truck.
Note: Fits 2003-2007 Ford F-250 and F-350 Super Duty Crew Cab only.
