Spec SR20DET S13/S14 Mini Twin R-Trim Clutch Kit

This is the SPEC Mini Twin R-Trim Clutch Kit, specifically made for the SR20DET engine in the S13 and S14 chassis of the 1989-1998 Nissan 240SX. If you're pushing significant power with your SR20DET, especially if you've upgraded the turbo or other engine components, you'll likely find that the stock clutch just can't keep up. This kit is designed to handle much higher torque loads, giving you the confidence to put that power down without worrying about clutch slip.

SPEC built this clutch kit with a dual-disc design, often called a mini-twin, which significantly increases the surface area for engagement compared to a single disc. This means it can dissipate heat more effectively and handle more torque. The R-Trim friction material is a popular choice for high-performance applications because it offers a good balance between holding power and drivability, making it suitable for both spirited street driving and track use. The kit includes two R-Trim clutch discs, two pressure plates, and the necessary hardware to get everything installed. This setup is known for its solid engagement and ability to manage the demands of a modified SR20DET engine.

When installing a clutch kit like this, it's always a good idea to have a new pilot bearing and rear main seal on hand, as these are easily accessible with the transmission out. Also, ensure your flywheel is in good condition or consider resurfacing or replacing it to ensure optimal clutch performance and longevity. This SPEC clutch kit is a well-built option for 240SX owners looking to upgrade their drivetrain to match their engine's power output.
