The RustBuster rear upper coil spring bucket for Chevrolet Avalanche, Suburban and GMC Yukon applications is the right-side mounting cup that secures the rear coil spring. It restores proper spring seating and alignment where the factory upper bucket locates the spring, providing a direct-fit suspension mounting point and helping preserve correct rear suspension geometry.
