Overview:

The ATI Damper is a high-quality, performance-oriented crankshaft damper designed specifically for a wide range of Scion, Subaru, and Toyota vehicles equipped with the 2.0L FA20 or 4U-GSE engines. Crafted from durable aluminum and featuring a 7.074-inch diameter with six grooves, this damper helps reduce crankshaft vibrations and improve engine smoothness.

Ideal for enthusiasts seeking enhanced engine reliability and refined drivability, the ATI Damper supports both daily driving and spirited performance applications. By effectively managing torsional vibrations, it contributes to the longevity of your engine components while maintaining OEM fitment and function.

Key Features:

This ATI Damper offers a blend of precision engineering and robust construction to meet the demands of performance and reliability:

• Constructed from lightweight, high-strength aluminum for durability and reduced rotational mass.
• Measures 7.074 inches in diameter, optimized for balance and vibration control.
• Features six grooves designed to fit factory accessory belts and pulleys precisely.
• Engineered specifically for the 2.0L FA20 and 4U-GSE engines found in select Scion, Subaru, and Toyota models.
• Incorporates a 10 percent underdrive (UD) ratio to slightly reduce accessory speeds, which can improve throttle response and accessory longevity.
• Compatible with a broad range of vehicles including Scion FR-S, Subaru BRZ, Toyota GR86, GR Corolla, GR Supra, Toyota 86, and various Scion iM, iA, iQ, tC, xB, and xA models.
• Designed to maintain OEM mounting points and accessory alignment for straightforward installation.

Construction & Design:

The ATI Damper is precision-machined from premium aluminum, ensuring a lightweight yet robust component that reduces rotational inertia compared to heavier factory dampers. Its six-groove design matches factory belt configurations, maintaining proper accessory drive function without modification.

The 7.074-inch diameter is carefully selected to optimize harmonic dampening for the FA20 and 4U-GSE engines, helping to minimize crankshaft vibrations that can lead to premature wear. The 10 percent underdrive feature slightly reduces the speed of driven accessories, which can contribute to improved throttle response and reduced parasitic losses.

Installation & Fitment:

This damper is a direct replacement for the factory crankshaft damper on compatible vehicles. It installs using existing mounting points and requires no cutting, drilling, or special tuning. This ensures a hassle-free upgrade that preserves factory accessory alignment and belt routing.

• Direct bolt-on installation with OEM hardware.
• No modifications to engine or accessories required.
• Compatible with factory belts and pulleys.

What's Included:

• ATI aluminum crankshaft damper with six grooves
• Installation instructions

Ideal For:

This ATI Damper is perfect for performance enthusiasts and daily drivers who want to enhance engine smoothness and reliability on their Scion, Subaru, or Toyota vehicles equipped with the FA20 or 4U-GSE 2.0L engines. It is especially suited for those upgrading other engine components or seeking improved throttle response and accessory drive efficiency without sacrificing OEM fitment.
