Cusco 87-91 Honda Civic EF B16A LSD Type-RS 1 Way

This is the Cusco Type-RS 1 Way Limited Slip Differential (LSD) specifically for the 87-91 Honda Civic EF with a B16A engine. When you install this, you're getting a well-built differential designed to put power down more effectively, especially when you're accelerating out of corners. It works by locking the two drive wheels together under acceleration, preventing one wheel from spinning freely while the other has traction. This means improved grip and a more stable feel when you're pushing the car.

The Type-RS is a popular choice because it offers a good balance of performance and drivability. It uses a unique cam mechanism that allows for smooth engagement, so it's not overly grabby during normal driving. The 1-way design means it primarily locks when you're accelerating, which is exactly what you want for sporty driving. This unit is built with strong materials to handle the demands of spirited driving and track use. Installation involves replacing your factory differential, so it's a job that requires some mechanical know-how and specific tools, often involving splitting the transmission case.

This LSD is a significant upgrade for anyone looking to improve their Civic's handling and traction. It's a component that really changes how the car feels when you're driving it hard. Make sure you have the necessary transmission fluid and any other associated seals or gaskets for a complete installation. It's a solid investment for performance-oriented Honda enthusiasts.
