Whiteline Plus 14+ Ford Mustang GT500/S550 Crossmember Mount Insert Kit – Improved Rear Crossmember Alignment and Handling

Description

The Whiteline Part Number KDT943 is a specially designed crossmember mount insert kit engineered for 2015 and 2016 Ford Mustang GT500 and S550 models. This innovative kit offers a simple installation process, making it an excellent choice for DIY enthusiasts looking to enhance their vehicle’s performance without extensive modifications. It works with the original factory bushing to eliminate over compliance, commonly known as ‘lost motion,’ resulting in a more responsive rear end during cornering and improved overall vehicle stability. By reducing rear crossmember misalignment and movement, this kit delivers a more positive and confident driving experience, especially during aggressive driving or spirited cornering.

Constructed with Whiteline’s latest synthetic elastomer formulation, the bushings resist oil, grease, ozone, and weathering, ensuring longevity and consistent performance over time. The specially bonded design provides optimized strength to handle high load-bearing applications, making it suitable for increased driving demands. Internal grease reservoirs enable continual self-lubrication, minimizing friction and maintaining optimal movement throughout the bushing’s lifespan. Each kit is supplied with high-pressure molybdenum disulphide-based grease, further extending the durability and smooth operation of the components.

Installation is straightforward, supported by an included detailed guide that walks users through each step. The inserts are engineered to work seamlessly with the original factory bushings, avoiding unnecessary removal or replacement of existing components. This design preserves the OEM setup while delivering significant improvements in handling and ride quality. Ideal for enthusiasts seeking a reliable upgrade that enhances the vehicle’s chassis response, the Whiteline crossmember mount insert kit is a practical and effective solution for maintaining and improving the performance of your Ford Mustang GT500 or S550 models.
