2004–2006 Scion xA / Scion xB 1.5L DOHC (1NZFE)

ACR-1724

Overview:

The Action Clutch Ironman Unsprung Clutch Kit is purpose-built for high-powered race vehicles requiring exceptional durability and consistent performance under extreme conditions. Designed specifically for the 2004 to 2006 Scion xA and xB models equipped with the 1.5L DOHC 1NZFE engine, this clutch kit delivers aggressive engagement with a precise on/off feel, ensuring maximum torque transfer without clutch chatter.

This kit is ideal for dedicated track use and motorsport applications where reliability and holding capacity are critical. It is not intended for street use and may produce some light engagement noise and gear rattle due to its race-focused design. Each kit undergoes rigorous quality checks by experienced engineers to guarantee dependable performance every time you push your vehicle to the limit.

Key Features:

Engineered with advanced materials and robust construction, the Ironman Unsprung Clutch Kit offers significant advantages over factory components:

• American Sintered Iron friction material for superior wear resistance and consistent engagement.
• Dual clamp load heavy-duty pressure plate designed to maximize torque holding capacity.
• Approximately 250% increased holding capacity compared to the factory clutch kit.
• Aggressive clutch engagement with a clean on/off feel, minimizing clutch chatter.
• Race-proven design optimized for high power output and extreme driving conditions.
• Quality checked and signed off by engineers with over 60 years of combined experience.
• Durable construction that withstands the rigors of track and competition use.
• Light engagement noise and gear rattle may occur, typical for race-spec clutches.
• Not suitable for street or daily driving applications.

Construction & Design:

The Ironman Unsprung Clutch Kit features a heavy-duty pressure plate with a dual clamp load system, ensuring even and secure clamping force across the friction surface. The friction disc utilizes American Sintered Iron, a material known for its excellent heat tolerance and friction stability, which is essential for maintaining performance during aggressive driving and repeated high-load engagements.

This unsprung design eliminates the traditional sprung hub, resulting in a more direct and immediate clutch engagement. While this enhances performance on the track, it also contributes to the characteristic engagement noise and gear rattle that are typical of race-oriented clutches.

Installation & Fitment:

This clutch kit is a direct fit replacement for the Scion xA and xB models from 2004 to 2006 equipped with the 1.5L DOHC 1NZFE engine. It installs using factory mounting points and is designed to integrate seamlessly with the existing transmission setup.

No modifications such as cutting, drilling, or special tuning are required for installation. However, due to the aggressive nature of this clutch, professional installation and proper setup are recommended to ensure optimal performance and longevity.

What's Included:

• American Sintered Iron friction disc
• Dual clamp load heavy-duty pressure plate
• Complete hardware kit for installation
• Quality assurance certification signed by an experienced engineer

Ideal For:

This clutch kit is perfect for serious racers and performance enthusiasts who demand maximum torque capacity and aggressive clutch engagement on the track. It is best suited for:

• Dedicated race vehicles and track day cars
• High horsepower builds requiring enhanced clutch holding power
• Drivers who prioritize performance and reliability over street comfort
• Motorsport applications where clutch chatter and noise are acceptable trade-offs
