Cusco LSD Type RS 1.5way Toyota JZS147 & JZS149 / JZS160 & JZS161 / UZS141 & UZS1143 & UZS145

This is the Cusco Type RS 1.5-way limited-slip differential (LSD) for specific Toyota models including the JZS147, JZS149, JZS160, JZS161, UZS141, UZS1143, and UZS145. A limited-slip differential is a crucial component for performance vehicles, especially those with rear-wheel drive. Unlike an open differential that sends power to the wheel with the least traction, an LSD directs torque to both drive wheels, significantly improving grip during acceleration out of corners and on slippery surfaces. This Cusco unit is a 1.5-way type, meaning it applies locking force during both acceleration and deceleration, offering a more stable and predictable feel when cornering.

The Type RS is Cusco's popular clutch-type LSD, known for its smooth engagement and durability. It utilizes a unique cone spring washer system that allows for consistent preload and smooth initial engagement, reducing chatter often associated with other clutch-type LSDs. The internal components are made from well-built steel, designed to handle the stresses of spirited driving and track use. This LSD is designed to fit directly into the factory differential housing, simplifying installation for mechanics familiar with differential work. Proper installation will require setting backlash and gear pattern, so referring to the manufacturer's installation instructions is recommended.

When installing a limited-slip differential, it's important to use the correct differential fluid. Cusco recommends specific LSD oil to ensure optimal performance and longevity of the unit. This differential is a significant upgrade for enthusiasts looking to enhance their vehicle's handling characteristics, providing improved traction for both street and track applications. It’s a well-known upgrade for these specific Toyota platforms, offering a noticeable improvement in how the car puts power down out of turns.
