Product Details
The Whiteline Front Upper and Lower Control Arm Bushing Kit fits the 1973-1986 Chevrolet C10 Suburban. The kit contains 8 bushings, 8 tubes, and grease. Drivetrain: RWD. The chassis code on the listing is C/K. The part number is W56421. It goes on the front of the vehicle.
Every time the wheel moves, the control arm swings on its bushings. When they are soft or worn, the arm shifts under load, the alignment changes as the car moves, and steering and braking feel less precise. A stiffer bushing cuts that unwanted movement while still letting the arm pivot freely. Polyurethane resists deflection far better than the soft rubber it replaces.
Whiteline rates the install as difficult and lists about 3 hours. An alignment is required after installation. Working on the same car? We also list Transmission Mount Bushing Kit and 26.9mm Front Sway Bar Mount Bushing Kit for the C10 Suburban.
Features
- Bushing compound: The elastomer formulation is chosen to shrug off oil, grease, ozone, and the elements.

- Bushing material: Made of polyurethane, which resists deflection better than soft rubber.
- Self-lubricating: Grease reservoirs inside the bushing feed lubrication as it moves.
