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

A 2-way LSD locks up during both acceleration and deceleration. A 1.5-way LSD locks up during acceleration and partially during deceleration. The Cusco Type RS allows you to adjust between these settings to suit your driving style and conditions.

What is required for installation?

Installation of a limited-slip differential is a complex job that requires specialized tools and knowledge. It typically involves removing the rear differential housing, disassembling it, and installing the new LSD unit. It is highly recommended to have this professionally installed by a qualified mechanic.

Does this LSD come with all necessary hardware?

This listing is for the Cusco LSD unit itself. Installation typically requires additional components such as new differential fluid, and potentially seals or bearings depending on the condition of your existing differential housing. Always refer to the manufacturer's installation guide for a complete parts list.

About this part

Product Details

The Cusco Type RS 2-Way limited-slip differential (LSD) is built with a unique cam mechanism that allows for adjustable lock-up settings, ranging from 1.5-way to 2-way engagement. This means you can fine-tune how the differential behaves under acceleration and deceleration, giving you more control during spirited driving and track use. For your 1999-2005 Lexus IS300 (JCE10/JCE15W), this LSD is designed to significantly improve traction, especially when exiting corners or in low-grip situations.

This differential uses a multi-plate clutch system, which is known for its smooth engagement and durability. The Type RS design focuses on providing a strong initial lock-up that gradually increases as more torque is applied. This characteristic helps to reduce wheel spin and bias power to the wheel with more grip, making your IS300 more predictable and responsive. The internal components are made from well-built materials, ensuring it can handle the stresses of performance driving. Installation involves replacing your factory open or limited-slip differential with this unit, requiring specialized knowledge and tools for proper setup and calibration.

When installing a limited-slip differential, it's crucial to follow the manufacturer's break-in procedure to ensure the clutch plates seat correctly. This process typically involves a period of gentle driving without hard acceleration or braking. Proper gear oil is also essential for the longevity and performance of the LSD; always use the specific type recommended by Cusco. This differential is a significant upgrade for IS300 owners looking to enhance their vehicle's performance capabilities on both the street and the track.
