Their robust design helps prevent bolt failure under high torque loads, making them ideal for spirited driving, track use, or heavy-duty applications. With ARP's reputation for quality and precision, you can trust these bolts to maintain optimal clamping force and improve overall engine reliability.

Key Features

ARP Flywheel Bolt Kits incorporate several advanced features that set them apart from standard hardware:

• Manufactured from aerospace alloy forging, ensuring exceptional strength and durability for demanding applications.
• Heat-treated prior to thread rolling and machining, providing consistent mechanical properties and resistance to fatigue.
• Exclusive flat 12-point head design allows for increased torque application and easier installation in tight engine bays.
• Enhanced shank diameter, larger than stock, to improve flywheel register and reduce the risk of bolt stretch or failure under high loads.
• Precisely machined threads and underhead length to ensure proper engagement and clamping force.
• Designed to withstand the stresses of high-performance driving, making them suitable for both daily driving and racing environments.
• Compatible with a variety of Toyota models, ensuring versatile application across different engine configurations.

Construction & Design

These ARP flywheel bolts are meticulously crafted from aerospace-grade alloy, which provides an excellent balance of strength, toughness, and corrosion resistance. The forging process ensures a uniform grain structure, contributing to their high tensile strength. The heat treatment process further enhances their mechanical properties, making them capable of handling the extreme stresses encountered during high-performance driving.

The unique flat 12-point head design not only facilitates easier installation and removal but also allows for higher torque application without stripping. The larger shank diameter improves the flywheel's register, ensuring a secure fit that maintains proper alignment and reduces vibration. All components are machined with precision to meet ARP's strict quality standards, guaranteeing a reliable and long-lasting fastening solution.

Performance & Reliability

By upgrading to ARP's flywheel bolts, you benefit from a significant increase in strength and reliability over OEM hardware. These bolts help support increased horsepower and torque levels, especially in high-performance or modified engines. Their superior clamping force ensures the flywheel remains securely attached during aggressive driving, reducing the risk of bolt failure or flywheel slippage. While they do not directly increase horsepower, they provide the essential mechanical integrity needed to support your vehicle's performance upgrades.

Installation & Fitment

Designed as a direct bolt-on replacement, these ARP flywheel bolts require no modifications or special tools for installation. They are compatible with a wide range of Toyota models from 2011 to 2025, covering various engine types and configurations. For optimal results, follow ARP's torque specifications and tightening sequence during installation. No cutting, drilling, or additional tuning is necessary, making this a straightforward upgrade for your engine assembly or repair process.
