Description

The ARB Gear Set K4 Side K1 Pin is a differential final drive gear designed to change the gear ratio of a vehicle's differential. This alteration can result in higher RPMs in top gear, which can be advantageous for off-roading or highway cruising. ARB, an Australian manufacturer established in 1975, focuses on producing durable, high-quality 4WD accessories built to withstand rigorous conditions. The gear set is described as being made from top-notch materials for reliability and has a straightforward installation process. WARNING: This product can expose you to Nickel, which is known to the State of California to cause cancer, birth defects, or other reproductive harm.
