What is the break-in procedure for this Cusco LSD?

Cusco typically recommends a specific break-in procedure for their RS differentials. This usually involves driving a certain mileage, often around 300-500 miles, with varied speeds and avoiding hard acceleration or braking. Always refer to the manufacturer's included instructions for the exact procedure.

Does this differential come with all the necessary installation hardware?

This listing is for the Cusco RS 2-way limited-slip differential unit itself. While it replaces the factory differential, it is recommended to check the manufacturer's specifications or consult with a professional to determine if any additional seals, bearings, or specialized installation fluids are required for your specific vehicle.

How does a 2-way LSD differ from a 1-way or 1.5-way LSD?

A 1-way LSD primarily locks under acceleration. A 2-way LSD locks under both acceleration and deceleration, providing more stability during cornering transitions. A 1.5-way LSD offers a compromise, locking strongly on acceleration and less so on deceleration.

About this part

Product Details

The Cusco RS 2-way limited-slip differential (LSD) is built with a unique clutch pack design that offers a distinct advantage for performance driving. This differential operates as a 1-way under acceleration and a 2-way under deceleration, meaning it actively locks both when you apply throttle and when you let off it. This provides a more stable and predictable feel during cornering, especially when transitioning between acceleration and braking. It’s designed to fit the rear of your 1989-1998 Nissan 240SX, whether it has a manual or automatic transmission, and also fits the 1984-1989 Nissan 300ZX manual transmission models.

Cusco's RS series LSDs are known for their smooth engagement and durability. The internal components are precisely machined to ensure reliable operation and longevity, even under demanding conditions. This unit is a popular choice for drivers looking to enhance their vehicle's handling characteristics, providing a significant improvement in traction out of corners and reducing unwanted wheel spin. Installation involves replacing the entire differential unit within the rear axle housing, so it's a job that requires careful attention to detail and proper setup to ensure optimal performance and to avoid premature wear.

When installing this differential, it's crucial to follow the manufacturer's recommended break-in procedure. This typically involves a period of gentle driving with specific mileage limitations and avoiding hard acceleration or braking. This process allows the clutch plates to properly seat, ensuring the LSD performs as intended and lasts for many miles to come. This unit is designed to work with the factory differential housing, making it a direct replacement for the stock unit.
