The RTS True Grip is a gear driven limited slip differential designed to be among the strongest and most durable in the industry. It combines the smooth operation of a limited-slip differential, with the strength of a fully-machined, forged steel case. Using 3x2 spiral gear technology, the True Grip delivers progressive and variable traction. Based off of throttle input, you are in control of how much traction is applied, which is great for situations where finesse is as important as extreme traction.
