Mevotech GK8359 Front Radius Arm Insulator Bushing

The Mevotech GK8359 is a front radius arm insulator designed to restore smooth, quiet suspension performance on light trucks and SUVs. This Original Grade replacement bushing provides the critical cushioning between the radius arm and frame mounting point, absorbing vibrations and impacts that would otherwise transfer to the vehicle's frame and cabin.

Key Features:

• Original Grade quality construction for reliable OEM-style performance
• Dampens suspension vibrations and road noise at the frame mounting point
• Helps maintain proper wheel alignment and steering control
• Prevents excessive radius arm movement during braking and acceleration
• Restores proper suspension geometry and ride quality

What It Does:

Radius arm insulators (also called radius arm bushings) are essential suspension components that control forward and backward wheel movement. The radius arm connects the front axle to the vehicle's frame, resisting lateral forces from braking and acceleration. The insulator bushing at the frame connection point provides the flexibility needed for suspension articulation while preventing metal-to-metal contact and isolating vibrations.

Signs of Wear:

Worn or damaged radius arm insulators can cause alignment changes, wandering steering, clunking noises from the front end over bumps, uneven tire wear, and harsh ride quality. Replacing worn insulators restores proper suspension function and driving comfort.

Mevotech has been providing quality steering and suspension components since 1982, with parts designed to meet or exceed OEM specifications through rigorous quality control processes.
