What is the main benefit of a twin-disc clutch over a single-disc clutch?

A twin-disc clutch uses two friction surfaces instead of one. This doubles the surface area for engagement, which significantly increases the torque capacity and helps to dissipate heat more effectively. This makes it ideal for high-performance vehicles or those with significant power modifications.

What components are included in the SPEC SD05MTR clutch kit?

This kit includes the twin clutch discs, a billet steel flywheel, and a new pilot bearing. It also comes with an alignment tool to assist with the installation process. It is designed as a comprehensive replacement for your stock clutch system.

What kind of pedal feel can I expect with this performance clutch?

The R-Trim designation on this SPEC clutch indicates a specific friction material and clamping force engineered for performance. While it offers substantially more holding power than a stock clutch, pedal feel can be firmer. It aims to provide a balance for drivers who want enhanced performance without an overly stiff pedal.

About this part

Product Details

SPEC is well-known for making strong drivetrain components, and their twin-disc clutch kits are a popular choice for serious performance applications. This particular kit, the SD05MTR, is built for the 2007-2009 Dodge Caliber SRT4 with the 2.4L engine, offering a significant upgrade over the stock clutch for vehicles that see hard use or have had their power increased.

This twin-disc setup uses two friction discs, which helps to spread the load and heat over a larger surface area. This design is crucial for handling the higher torque output often found in modified SRT4s, reducing the chance of clutch slip and premature wear. The kit includes a billet steel flywheel, which is a solid foundation for the twin discs, ensuring proper alignment and durability. It also comes with a new pilot bearing and alignment tool, making the installation process more straightforward. The R-Trim designation indicates a specific friction material and clamping force designed to balance holding power with a manageable pedal feel for a performance clutch.

When installing a twin-disc clutch like this, it's important to ensure your flywheel and pressure plates are properly torqued according to SPEC's instructions. Because this is a performance-oriented component, it's often paired with other drivetrain upgrades to maximize its benefits. This kit is designed to handle demanding conditions, providing a robust connection between your engine and transmission.
