SPEC Stage 5 Clutch Kit

2007–2010 Scion tC / 2008–2015 Scion xB2

ST485

Overview:

The SPEC Stage 5 Clutch Kit is engineered for serious enthusiasts driving the 2007–2010 Scion tC and 2008–2015 Scion xB2 models. Designed to handle extreme torque demands, this clutch kit offers a significant upgrade over stock components, making it ideal for high-performance street driving and drag racing applications. While it remains street drivable, the Stage 5 clutch prioritizes maximum friction and durability over everyday comfort, delivering aggressive engagement and exceptional holding power for modified engines.

Built to withstand torque capacities up to 670 ft/lbs, this clutch kit is perfect for drivers pushing their vehicles to the limit, whether on the strip or during spirited autocross events. The SPEC Stage 5 kit provides a reliable and consistent clutch feel that enhances vehicle control and power transfer under demanding conditions.

Key Features:

The SPEC Stage 5 Clutch Kit combines advanced materials and engineering to deliver superior performance and durability. Key features include:

• Full-metallic friction disc offering the highest possible coefficient of friction for maximum grip
• Solid 12-rivet hub design for enhanced strength and torque capacity
• High clamp pressure pressure plate to ensure firm clutch engagement
• Heat-treated assembly components for increased durability and resistance to wear
• High torque sprung hub and disc assembly to reduce drivetrain shock and improve pedal feel
• Includes bearing and tool kit on select models (please inquire for availability)
• Engineered for extreme street use, drag racing, pulling, and autocross
• Torque capacity rated at 670 ft/lbs, suitable for heavily modified engines

Construction & Design:

The SPEC Stage 5 clutch kit features a robust construction focused on strength and longevity. The full-metallic friction disc is designed to provide maximum friction without sacrificing heat resistance, making it ideal for high-stress driving conditions. The solid 12-rivet hub ensures a secure connection between the disc and transmission input shaft, minimizing the risk of failure under high torque loads.

All components undergo heat treatment to enhance their structural integrity and wear resistance. The pressure plate is engineered to deliver high clamp force, ensuring consistent engagement and minimizing slippage during aggressive launches and gear shifts. This meticulous construction results in a clutch kit that can reliably handle the demands of extreme street and competitive racing environments.

Installation & Fitment:

The SPEC Stage 5 Clutch Kit is a direct fit replacement for the 2007–2010 Scion tC and 2008–2015 Scion xB2 models. Installation requires standard clutch replacement procedures and may benefit from professional installation to ensure proper alignment and adjustment. Due to the aggressive nature of this clutch, some drivability compromises such as increased pedal effort and engagement harshness are expected compared to OEM clutches.

No major modifications to the transmission or drivetrain are typically necessary, but it is recommended to inspect the flywheel and related components during installation to ensure compatibility and optimal performance.

What's Included:

• Full-metallic friction disc with 12-rivet solid hub
• High clamp pressure pressure plate
• Sprung hub and disc assembly
• Bearing and tool kit (included on select models, please inquire)

Ideal For:

This clutch kit is ideal for Scion tC and xB2 owners who demand maximum torque capacity and clutch durability for extreme street driving, drag racing, and autocross. It suits enthusiasts who have upgraded their engines and require a clutch that can handle increased power without slipping. Drivers seeking a street-friendly clutch with OEM-like smoothness should consider less aggressive options, as the Stage 5 prioritizes performance over comfort.
