OS Giken Toyota SUPRA 1JZGTE (R154 Gearbox) R4C Series Quad Plate w/ 26 GM Spline

This is the OS Giken R4C Series Quad Plate Clutch Kit, designed specifically for the Toyota Supra with a 1JZGTE engine and the R154 gearbox. You'll receive the complete quad plate clutch assembly, ready for installation. This clutch is built for serious performance applications where handling significant power is a must, offering a robust solution for high-output 1JZGTE builds.

The R4C series from OS Giken is a quad-plate clutch system, meaning it uses four friction discs. This design dramatically increases the surface area for engagement, allowing it to handle extreme torque loads without slipping. The 26 GM spline count is a key specification for ensuring proper mating with the transmission input shaft. OS Giken is well-known for its advanced clutch technology, and this unit reflects that with its durable construction and ability to provide consistent engagement even under heavy use. While it's a high-performance clutch, OS Giken aims for a balance between extreme capability and drivability, though a multi-plate clutch will always have a firmer engagement feel than a stock clutch.

When installing a multi-plate clutch like this, it's important to ensure your flywheel is in excellent condition, as it's a critical component for clutch operation. OS Giken clutches are a popular choice for enthusiasts looking to maximize their vehicle's drivetrain performance and reliability under demanding conditions. This kit is a substantial upgrade for any 1JZGTE swapped vehicle or a heavily modified Supra running the R154 transmission.
