SuperPro Rear Differential-to-Subframe Bushing Kit for 2015-2023 Ford Mustang
The SuperPro TRC4758 Rear Differential-to-Subframe Bushing Kit, engineered to deliver unmatched drivetrain stability and responsiveness. Designed for enthusiasts who demand precision on the street or track, this kit replaces the soft, fast-wearing OEM rubber bushings with SuperPro’s advanced polyurethane and Polyelast hybrid materials. The result is a bushing kit that ensures a firm connection between the rear differential and subframe, minimizing wheel hop, improving throttle response, and maintaining alignment under high-performance driving conditions—all while preserving cabin comfort with OEM levels of noise, vibration, and harshness (NVH) isolation.
Why Choose the SuperPro Bushing Kit?
Crafted in Brisbane, Australia, by SuperPro, a leader in aftermarket suspension components with over 40 years of experience, the TRC4758 kit is built to withstand the rigors of aggressive driving, including track use and high-power applications. Unlike stock rubber bushings that flex and degrade quickly, this kit’s Polyelast and polyurethane construction offers 15 times the durability of rubber, ensuring long-lasting performance without compromising ride quality. Whether you’re launching hard at the drag strip or carving corners at the track, the TRC4758 kit keeps your Mustang’s drivetrain secure, channeling power directly to the wheels for improved traction and control.
