ARP GR86 / BRZ Flywheel Bolts

Overview

Upgrade your Subaru’s drivetrain hardware with this premium flywheel bolt kit engineered for strength, precision, and reliability.

Designed as a direct replacement for the factory bolts on Subaru FA20/FA24 engines — commonly found in the Toyota 86, and Subaru BRZ — this kit delivers superior performance over OEM hardware.

High-Strength Construction

Each bolt in the kit is forged from aerospace-grade alloy and heat-treated prior to thread rolling and machining, giving it far greater tensile strength and fatigue resistance than stock bolts. The extra-robust construction helps ensure dependable fastening between the crankshaft and flywheel, even under high RPM or spirited driving conditions.

• Flat 12-point head design — allows better torque application and easier access during installation.
• Larger-than-stock shank diameter — improves flywheel register for more accurate alignment and reduces risk of bolt stretch or failure.
• Thread Size: M10 × 1.00, with a 0.925" under-head length — ideal for FA20/FA24 flywheel mounting requirements.
• Finished with a durable black oxide coating for corrosion resistance.
