Show original supplier description
The Whiteline WL-KDT943 is a rear subframe mount bushing insert kit engineered to work with the original factory bushing, specifically targeting the elimination of 'lost motion' or excessive compliance in the rear crossmember. This design dramatically reduces rear crossmember misalignment and movement, resulting in a more direct and positive feel from the rear end during spirited driving and cornering. The kit features Whiteline's advanced synthetic elastomer formulation, known for its exceptional resistance to automotive fluids like oil and grease, as well as environmental factors such as ozone and weathering. For enhanced durability and performance, the inserts are supplied with extreme pressure molybdenum disulfide (LM) based grease, ensuring extended service life. Internal grease reservoirs are incorporated for continual self-lubrication and optimal friction management, while the specially bonded design provides the optimized strength required for high load-bearing applications. The kit includes an install guide with detailed instructions. The WL-KDT943 is compatible with 2015-2025 Ford Mustang RWD models, including GT, Shelby GT350, and Dark Horse trims. Fitment should always be verified for your specific vehicle year, make, model, and trim.
