No Politics Racings (NPR) limited slip differential are the pinnacle in high-speed track and racing applications specifically designed to increase grip and decrease lap times.
Our LSDs provide lock-up on both acceleration and deceleration which can be adjusted by using our exclusive dual ramp design allowing for numerous lock-up percentages to be utilized depending on track conditions and car configuration. Multiple friction disc and plain plate configurations are possible with our standard configuration being 4 friction discs and 4 plain discs and our Torque Flow model being 6 plain discs and 6 friction discs.
NPR’s aerospace technology friction discs dramatically increase the useful life of our LSDs compared to OEM versions. All vital areas of NPR LSDs are high precision ground and shot-peened for added strength and durability then, finished with an Isotropic Super Finish (REM).

Benefits of a limited-slip differential
The main advantage of a limited-slip differential is demonstrated by considering the case of a standard (or "open") differential in off-roading situations where one wheel has no contact with the ground. In such a case (with a standard differential), the non-contacting wheel will receive 100% of the power, while the contacting wheel will remain stationary. The torque transmitted will be equal at both wheels, and therefore, will not exceed the threshold of torque needed to move the wheel with traction. In this situation, a limited-slip differential prevents 100% of the power from being allocated to one wheel, and thereby keeping both wheels in powered rotation.
