Honda Flywheel Bolt Kit Fits 1.8/2.0L DOHC

The Honda Flywheel Bolt Kit Fits 1.8/2.0L DOHC from ARP is a professional-grade fastening solution engineered for Honda B-Series engines demanding reliability under high-load conditions. Originally designed for technicians and enthusiasts who refuse compromise on critical engine assembly points, this kit addresses the real-world need for superior clamping force and fatigue resistance where OEM hardware falls short. Flywheel bolts experience repeated stress cycles during every engine start, acceleration, and load transfer—making material and design selection non-negotiable for engines running increased boost, higher compression, or aggressive tuning.

This Pro Series kit features chromoly construction with black oxide finish, delivering superior tensile strength compared to standard steel fasteners while resisting corrosion and galling during installation and removal cycles. Each bolt measures 12 mm × 1.00 thread pitch, 0.890 inches in length, and features a 12-point head geometry that distributes load more evenly than conventional hex heads and reduces stress concentration at critical transition zones. The set includes eight bolts—the complete complement required for most Honda B-Series applications—ensuring uniform clamping and eliminating the risk of mixed hardware that compromises joint integrity. Black oxide coating provides both durability and a professional appearance while aiding in torque consistency by reducing friction variation between fastener and application.

Technicians, engine builders, and performance-minded Honda owners benefit most from this kit when reassembling engines destined for track duty, forced induction, or sustained high-RPM operation. Proper installation requires adherence to manufacturer torque specifications and sequential tightening patterns to achieve uniform preload across all eight fasteners. Compatibility extends to Honda 1.8L and 2.0L DOHC B-Series engines commonly found in Civic, Integra, and CRX platforms; verify your specific engine configuration before ordering. The lightweight design (0.74 lbs total) reflects the precision engineering inherent to ARP's manufacturing process, ensuring no excess material while maintaining the strength margins critical to engine longevity.
