AC138FW

Overview:

The Action Clutch Lightweight Flywheel is a high-performance upgrade designed specifically for the 2008 to 2015 Scion xB equipped with the 2.4L 2AZ-FE engine. Crafted from durable chromoly steel, this flywheel is engineered to reduce rotational mass, delivering quicker engine response and improved throttle feel. Ideal for both street-driven vehicles and high-tuned race applications, it offers enhanced durability and thermal capacity to withstand demanding driving conditions.

Whether you are looking to improve your vehicle’s responsiveness or preparing your Scion xB for spirited driving or track use, this lightweight flywheel provides a reliable and long-lasting solution. Its heat-treated construction ensures it can endure extreme RPMs, making it suitable for enthusiasts who push their engines hard.

Key Features:

This chromoly lightweight flywheel combines strength and performance benefits, making it a smart upgrade for your Scion xB.

• Constructed from high-strength chromoly steel for superior durability and resistance to wear.
• Heat-treated to increase thermal capacity and withstand extreme operating temperatures.
• Tested up to 18,000 RPM, ensuring reliability under high-rev conditions.
• Significantly reduced weight compared to the factory flywheel for faster engine response.
• Resurfacable design extends the service life and maintains optimal performance.
• Improves throttle response and acceleration by reducing rotational inertia.
• Compatible with stock clutch components and mounting points for straightforward installation.
• Designed for light to high-tuned street and race vehicles, balancing performance and durability.

Construction & Design:

The flywheel is precision-engineered from chromoly steel, a material known for its excellent strength-to-weight ratio and heat resistance. The heat treatment process enhances its durability, allowing it to handle the stresses of aggressive driving and high RPMs without warping or cracking. Its lightweight design reduces the rotational mass of the engine’s crankshaft assembly, which translates into quicker revving and improved throttle response.

Additionally, the flywheel’s resurfacing capability means it can be maintained and reused multiple times, providing long-term value and consistent performance throughout its lifespan.

Installation & Fitment:

This lightweight flywheel is a direct fit replacement for the factory flywheel on the Scion xB models from 2008 through 2015 with the 2.4L 2AZ-FE engine. It uses the OEM mounting points and is compatible with stock clutch assemblies, making installation straightforward for experienced mechanics or performance shops.

Note that due to the reduced rotational mass, some increase in noise, vibration, and harshness (NVH) may be noticeable compared to the factory flywheel. No cutting, drilling, or special tuning is required for installation.

• Direct bolt-on replacement for 2008–2015 Scion xB 2.4L (2AZ-FE)
• Compatible with factory clutch and pressure plate
• No modifications or special tuning needed
