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. Precision-Engineered Features 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
