Cusco PRO-ADJ LSD RS AP1

The Cusco PRO-ADJ LSD RS AP1 utilizes a unique cone plate system, a design choice that allows for a significant amount of initial torque and a wide range of lock-up adjustments. This isn't just about locking the wheels together; it's about fine-tuning how and when that lock-up happens, which is crucial for performance driving. The RS (Real Special) designation in its name points to its advanced clutch type mechanism, designed to offer a more progressive engagement compared to traditional clutch-based limited-slip differentials. This means you get a smoother transition into lock-up, reducing jerky behavior during cornering and improving overall stability.

Built with durability in mind, the internal components are made from high-strength materials to withstand the rigors of spirited driving and track use. The adjustability is a key feature here; mechanics can dial in the initial torque and ramp angles to match specific driving styles or track conditions. This level of customization is what sets the PRO-ADJ apart, allowing for a truly tailored differential setup. The unit is designed to fit specific transmissions, and proper installation is key to unlocking its full potential. It's a substantial upgrade for anyone looking to significantly enhance their vehicle's traction and handling characteristics.

When installing this differential, it's important to use the correct differential fluid recommended by Cusco, as this plays a vital role in the performance and longevity of the clutch plates. The unit comes ready for installation, but ensure all associated seals and bearings are in good condition or replaced as part of the job. This differential is a serious component for performance-oriented vehicles, offering a noticeable improvement in grip out of corners and better power delivery under acceleration.
