Whiteline Plus Crossmember Mount Insert Kit for Select 2015-2026 Ford Mustang (KDT943)
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits select 2015-2026 Ford Mustang models, including EcoBoost, GT, V6, Bullitt, Mach 1, Shelby GT350, GT500, and Dark Horse.
The Whiteline Plus KDT943 Crossmember Mount Insert Kit is a precision-engineered solution designed to eliminate "lost motion" in the rear subframe without the need for a full bushing press-out. These inserts fill the voids in the factory bushings, significantly reducing crossmember misalignment and movement during high-load cornering. By stabilizing the rear end, this kit provides a more positive, predictable feel through the chassis while maintaining a level of comfort suitable for daily driving.
- Manufactured from a proprietary synthetic elastomer for superior resistance to oil, grease, ozone, and environmental weathering.
- Specially bonded design optimized for high-load automotive applications.
- Internal grease reservoirs provide continuous self-lubrication to manage friction and prevent noise.
- Easy DIY installation inserts directly into original factory bushings.
- Includes extreme pressure molybdenum disulphide (LM) based grease for long-term service life.
- Manufacturer Part Number: KDT943
