ARP Powersports engine and accessory bolt kits contain professional-quality fasteners. They're manufactured with premium materials and finishes that are nominally rated at 180,000 psi tensile strength—superior to OEM bolts and better than hardware grades. Motorcycles run at very high rpms and put tremendous stress on lightweight parts. The task is holding your engine and accessories together during those times. ARP Powersports fasteners are a convenient and easy way to assemble your engine with confidence, knowing that ARP is up to the challenge. Choose the kit designed for your specific bike.
