Spec Clutch SH99MTR Spec R-Trim Twin Disc Clutch Kit

The Spec Clutch SH99MTR R-Trim Twin Disc Clutch Kit is a high-performance dual-disc clutch system engineered for serious street and track applications. Spec's R-Trim series delivers an aggressive torque capacity upgrade over the stock clutch, making it an ideal choice for highly modified vehicles demanding maximum power transfer and durability.

Spec's twin disc design splits clamping load across two friction discs, reducing pedal effort while dramatically increasing torque holding capacity. The R-Trim designation indicates a race-oriented friction material compound that offers exceptional grip, heat resistance, and longevity under sustained high-load conditions.

Key Features:

• Twin disc design for increased torque capacity with reduced pedal effort
• R-Trim race-grade friction material for high heat tolerance and aggressive engagement
• Precision-machined billet floater plate for consistent disc spacing and clamping force
• Heavy-duty pressure plate assembly with upgraded diaphragm spring
• Designed for high-horsepower street/strip and track use
• Includes clutch discs, pressure plate, floater, and alignment tool
• Direct bolt-on fitment — no flywheel or bellhousing modification required

The Spec R-Trim Twin Clutch Kit SH99MTR is built for performance enthusiasts who have pushed beyond the limits of single-disc clutch systems. Whether on the drag strip or road course, this kit provides the reliability and power handling necessary to keep pace with serious engine builds.
