Cusco PRO-ADJ LSD RS CT9A Rear

This listing is for the Cusco PRO-ADJ LSD RS CT9A Rear Differential. This is a high-performance limited-slip differential designed to improve traction and handling, especially during spirited driving or track use. It's a well-built unit that aims to put power down more effectively by controlling wheel spin.

The Cusco PRO-ADJ LSD RS (Type RS) is a clutch-type limited-slip differential. It uses a series of clutch plates that engage under acceleration to limit wheel speed difference between the left and right rear wheels. This specific model is designed for the CT9A chassis, which is commonly associated with Mitsubishi Lancer Evolution models. The 'PRO-ADJ' designation indicates that it offers adjustable settings, allowing a mechanic to fine-tune the locking force to suit specific driving conditions or driver preference. This adjustability is a key feature for racers and serious enthusiasts looking to optimize their vehicle's performance. The Type RS is known for its smooth engagement and progressive locking action, making it a popular choice for those seeking improved grip without overly aggressive or jerky behavior.

When installing a limited-slip differential like this, it's important to use the correct differential fluid as specified by Cusco. Proper break-in procedures are also crucial for the longevity and performance of the clutch plates. This differential is a significant upgrade for vehicles used in performance driving scenarios, offering a noticeable improvement in cornering stability and acceleration out of turns.
