KellTrac Rear Shock Bearing Upgrade Kit, Lower, Pair (KTI-SBU15RL) - 2015–2026 Mustang
The KellTrac Rear Shock Bearing Upgrade Kit is designed for Mustang owners who want maximum suspension precision from their Viking rear shocks. By replacing the factory-style soft lower bushings with high-quality spherical bearings, this kit eliminates deflection at the shock mount—allowing the shock to react instantly and consistently under load.
Ideal for drag racing, road course, autocross, and other performance-focused applications, this upgrade improves shock response, traction, and overall rear suspension control. Built using premium materials and precision-machined components, the KellTrac bearing kit delivers the durability and performance demanded by serious builds.
This system is recommended for enthusiasts who prioritize performance over NVH, as spherical bearings may introduce additional noise or vibration compared to rubber or polyurethane bushings.
