Unlike some competitor parts that require presses or special tools for installation, the PERRIN Diff Lockdown is designed for quick and easy installation, taking 45 minutes or less with just basic tools.

Noise, Vibration, Harshness

The PERRIN Rear Differential Lockdown reduces movement from the rear differential to enhance driver feel while adding minimal noise, vibration, and harshness (NVH).
