What is the difference between a 1-way, 1.5-way, and 2-way LSD?

A 1-way LSD primarily locks under acceleration. A 1.5-way locks under acceleration and partially under deceleration, offering stability during corner entry. A 2-way locks equally under both acceleration and deceleration, providing maximum stability but can feel more abrupt.

What type of gear oil should I use with this Cusco LSD?

It is recommended to use a high-quality gear oil specifically formulated for limited slip differentials. Always consult the Cusco installation manual or a qualified mechanic for specific fluid recommendations.

Can I install this LSD on my 350Z if it has an open differential?

No, this differential will not fit a 350Z with an open differential without sourcing additional specific parts from Nissan. Please verify your current differential type before purchasing.

About this part

Product Details

If you're looking to get the most out of your 2003-2009 Nissan 350Z on the track or during spirited driving, upgrading your differential is a key step. This Cusco RS 1.5-way limited slip differential (LSD) is designed to significantly improve traction and handling by controlling the speed difference between your rear wheels. It's a well-built unit that helps put power down more effectively, especially when exiting corners or in situations where one wheel might lose grip.

The RS series from Cusco is known for its smooth engagement and predictable operation. This 1.5-way design means it locks up under acceleration, providing strong traction, and also offers partial locking under deceleration, which helps stabilize the rear end during corner entry. This can make a notable difference in how the car feels and handles during aggressive maneuvers. The unit is constructed with durable materials to withstand the demands of performance driving. It's important to note that this differential will not fit vehicles with an open differential without additional parts from Nissan, so be sure to check your existing setup.

Installing a limited slip differential is a significant upgrade for your 350Z's drivetrain. It requires careful installation, often involving removing the rear axle and differential housing. For optimal performance and longevity, it's recommended to use a high-quality gear oil specifically designed for limited slip differentials. This Cusco unit is a solid option for 350Z owners looking to enhance their vehicle's performance capabilities.
