What is a 1.5-way limited slip differential?

A 1.5-way LSD locks up during acceleration to send power to both rear wheels. It also provides a partial lock on deceleration, which helps stabilize the car when entering corners. This offers a good balance of traction and predictable handling for performance driving.

What is the break-in procedure for this differential?

Cusco typically recommends a specific break-in procedure for their RS differentials. This usually involves driving gently for a certain mileage, avoiding hard acceleration or braking, followed by an initial oil change. Always refer to the manufacturer's included instructions for the exact steps.

What type of fluid should I use with this differential?

It is crucial to use a high-quality, specialized differential fluid recommended for limited slip differentials. Using the wrong type of fluid can damage the LSD and affect its performance. Consult the Cusco installation manual or a qualified mechanic for the specific fluid viscosity and type.

About this part

Product Details

This is the Cusco RS 1.5-way limited slip differential (LSD) specifically for the rear of your 1986-1987 Toyota Corolla AE86 kouki Levin or Trueno. If you're looking to put down power more effectively, especially during spirited driving or track use, an LSD is a significant upgrade over a standard open differential. It helps distribute torque to both rear wheels, preventing one wheel from spinning freely while the other has grip. This means better acceleration out of corners and more stable handling under load.

The RS series from Cusco is known for its advanced design, offering a 1.5-way engagement. This means it locks up during acceleration for maximum traction, but also provides a degree of locking on deceleration. This characteristic is favored by many drivers for its predictable behavior and improved stability when entering and exiting turns. The differential is constructed with robust materials and precision machining to handle the stresses of performance driving. Installation involves replacing your factory differential, and it's recommended to have this done by a qualified mechanic who understands differential setups to ensure proper preload and backlash settings.

When installing this differential, it's important to follow the manufacturer's break-in procedure carefully. This typically involves a period of gentle driving followed by an oil change to remove any initial wear particles. Using the correct differential fluid is also crucial for longevity and performance. This Cusco LSD is a well-built component designed to enhance the driving dynamics of your AE86 Corolla.
