The Prothane Motion Control 18-103 body mount bushings replace worn factory rubber mounts with high-durometer polyurethane for a solid, rattle-free connection between body and frame. Prothane’s precision-molded design provides the stiffness needed for proper chassis response without the NVH brutality of solid metal mounts.

Molded from Prothane’s proprietary polyurethane blend at 95A durometer. Includes corrosion-resistant steel sleeves and hardened mounting washers for all body mount positions. Each bushing is CNC-machined for exact dimensional accuracy. The material resists oil, ozone, and compression set far better than OEM rubber.

Complete bolt-in kit — all body mount positions included for a thorough chassis refresh. Requires a floor jack and basic hand tools to support the body during installation. Prothane recommends using their PTFE-based assembly lubricant for squeak-free, long-lasting performance.

Tighten the chassis with Prothane. Installation with polyurethane-compatible grease ensures long-term noise-free operation and maximum service life from these high-performance bushings. The 18-103 body mount kit eliminates flex and noise permanently. Order yours now.

Frequently Asked Questions

Does the Prothane body mount bushing kit fit the factory body mounts on my your vehicle?

Yes, the Prothane body mount bushing kit is designed to replace the factory rubber body mounts on your your vehicle using the original mounting locations. Each bushing measures approximately 2.5 inches in diameter and 1.0 inch in height to match the OEM dimensions. These Prothane polyurethane body bushings maintain the factory ride height and body alignment specifications.

What is the durometer of the Prothane polyurethane body bushings for my your vehicle?

The Prothane polyurethane body bushings for your your vehicle have a durometer rating of 85A on the Shore hardness scale for a balance of reduced body roll and comfort. This is approximately 20 percent stiffer than the factory rubber mounts rated at around 70A durometer. These Prothane body bushings firm up the chassis without transmitting excessive vibration into the cabin.

Will the Prothane body bushings reduce cab vibration on my your vehicle during highway driving?

Yes, the Prothane body bushings reduce unwanted cab movement and vibration on your your vehicle by providing consistent clamping force between the body and frame. The polyurethane material at 85A durometer absorbs high-frequency vibrations better than worn factory rubber on your your vehicle. These Prothane body mount bushings eliminate the loose, wandering feeling from degraded OEM body mounts.

Do the Prothane body mount bushings require removing the cab to install on my your vehicle?

No, the Prothane body mount bushings can be installed on your your vehicle by jacking up the body slightly at each mount location without removing the cab. You will need to loosen all body mount bolts and raise the body approximately 2 inches to access each bushing. These Prothane body bushings are replaced one at a time to maintain body alignment throughout the process.

How much does the Prothane body bushing kit weigh for my your vehicle?

The Prothane body bushing kit for your your vehicle weighs approximately 5 to 8 pounds for the complete set of bushings, washers, and sleeves. Each individual polyurethane bushing weighs roughly 0.4 pounds compared to the heavier rubber originals. These Prothane body bushings include metal reinforcement sleeves that add approximately 0.2 pounds per mount for structural integrity.

Can I reuse my your vehicle's factory body mount bolts with the Prothane bushings?

Yes, you can reuse the factory body mount bolts with the Prothane body bushings on your your vehicle as long as they are free of rust and thread damage. The bolt size is typically 12mm or 14mm diameter depending on the specific body mount location on your your vehicle. These Prothane body bushings use the same inner sleeve diameter as the factory hardware for compatibility.
