ARP Pro Series Flywheel Bolt Kit - Subaru EJ/FA/FB & Toyota GR86/BRZ

The Ultimate Insurance Policy for High-Performance Drivetrains
When you drop in a heavy-duty clutch or a lightweight chromoly flywheel, upgrading your flywheel hardware isn't just an afterthought—it's mandatory safety. Standard factory flywheel bolts are designed for stock loads, and reusing them is a massive risk. The ARP Pro Series Flywheel Bolt Kit (260-2801) provides the bulletproof clamping force required to lock your flywheel securely to the crankshaft, preventing catastrophic shearing or loosening under hard launches, high-RPM shifts, and extreme track abuse.

Forged Premium Aerospace Alloy
Far superior to OEM grade hardware, these Pro Series fasteners are hot-forged from 8740 chrome-moly steel and heat-treated to a staggering 200,000 psi tensile strength. ARP precision-machines the threads after heat-treating (not before) to ensure 10 times better fatigue life than standard bolts. Designed with a custom low-profile 12-point head design, they offer maximum clearance under your clutch disc sprung hub while providing a rock-solid surface for your socket during final torque sequences.

• 200,000 PSI Tensile Strength: Engineered to survive extreme torsional twisting forces that snap factory hardware.
• Premium 12-Point Design: Low-profile head provides maximum clearance for performance clutch disc hubs.
• Reusable Design: Unlike OEM stretch-style bolts which must be thrown away after one use, ARP Pro Series bolts are fully reusable.
• Complete Kit: Includes a full set of 8 bolts and a packet of ARP Ultra-Torque Fastener Assembly Lubricant.2. Technical

The Nameless "Installation" Pro-Tip:

Follow the Lube Instructions Explicitly: Do not install these bone-dry, and do not use regular engine oil or standard anti-seize. You must apply a thin layer of the included ARP Ultra-Torque Fastener Assembly Lubricant underneath the bolt heads and on the threads before torqueing. This ensures the fastener reaches its exact design preload without binding.

The Star Pattern Torque Process: Always torque flywheel bolts in a crisscross "star" pattern in progressive stages. For this specific M10 kit using ARP lube, torque them down in three even steps (e.g., 25 ft-lbs, 45 ft-lbs, and a final step to 58 ft-lbs). Use a quality 12-point socket so you don't round off the specialized heads!
