Whiteline Upper Control Arm & Lower Bushing – 99-05 Chevrolet Silverado 1500

Whiteline W56420 provides upper control arm & lower bushing for 99-05 Chevrolet Silverado 1500.

How It Works

Control arm bushings locate the arm while accommodating its movement. Their compliance affects how closely the suspension maintains its intended alignment as braking, cornering and road loads change. The exact mounting location matters: inner, outer, forward and rearward bushings perform different roles and are not interchangeable simply because they fit the same vehicle.

Installation & Selection

Inspect the arm, housing, sleeves and adjacent joints before fitting.
