What is a 1-way limited slip differential and how does it work?

A 1-way limited slip differential primarily locks under acceleration. This means it helps send power to both rear wheels when you're accelerating out of a corner, reducing wheelspin and improving traction. It generally disengages or has minimal effect when you're not accelerating.

What does the '35&45' mean in the product name?

The '35&45' refers to the adjustable ramp angles within the differential. These angles control how the differential locks up under acceleration. Having adjustable angles allows you to fine-tune the differential's behavior to suit your driving style and track conditions.

What else might I need to install this differential?

Installing a differential typically requires specialized tools for setting gear backlash and preload. You may also need new axle seals, differential fluid, and potentially a gasket for the differential cover. It's recommended to consult the manufacturer's installation instructions or a professional mechanic for a complete list of required parts and tools.

About this part

Product Details

If you're looking to get the most out of your 1988-1997 Toyota Corolla on the track or during spirited drives, a limited slip differential (LSD) like this Cusco RS model can make a notable difference. This type of differential helps manage power delivery to both rear wheels, especially during cornering, by allowing a controlled amount of slip. This means less wheelspin and more consistent traction when you need it most, improving your car's ability to put power down and handle dynamically.

Cusco's RS series differentials are known for their smooth engagement and adjustability. This particular unit is a 1-way clutch type, meaning it primarily locks under acceleration. The '35&45' in its name refers to the adjustable ramp angles, allowing you to fine-tune how aggressively it locks up. This adjustability is a key feature for racers and performance enthusiasts who want to dial in their car's handling characteristics. The differential is built with durable materials designed to withstand the stresses of performance driving, ensuring reliable operation.

This differential is designed as a direct replacement for your stock unit, simplifying the installation process. While it's a significant upgrade for performance, it's important to note that installing an LSD typically requires specialized knowledge and tools, often involving removing the rear axle and potentially setting gear backlash. If you're not comfortable with this level of work, it's best to have a professional mechanic handle the installation to ensure it's set up correctly for optimal performance and longevity.
