    Keep your suspension quiet and properly located with the Delphi Suspension Control Arm Bushing (TD4421W), a rear-position bushing that installs as a direct-fit replacement for the 1963-1982 Chevrolet Corvette. It cushions the connection between the rear control arm and the chassis, helping to isolate road vibration and dampen noise so the suspension moves the way it should.

    Delphi builds this bushing to OE standards, drawing on the OE safety technology fitted to millions of vehicles worldwide.

    • Tested to the extreme: validated across temperatures below -40°C to over 120°C and exposed to 720 hours of salt spray, with extensive dimensional and material analysis for close OE-to-aftermarket compatibility.
    • Built for consistent life: manufactured to deliver consistent service life and to reduce noise.
    • Smoother ride: designed to reduce vibration through the suspension.
    • Ready to install: includes the necessary accessories for a complete job.

    A worn suspension control arm bushing can lead to clunking, imprecise handling, and vibration; if a failed bushing is the cause, this Delphi unit replaces it.
