ARP Hardware Pack for BMW Toyota B58

BMW Toyota B58 Complete ARP Engine Hardware Package – All-In-One Strength for High-Power Builds Upgrade your entire bottom and top end with the BMW Toyota B58 Complete Engine Hardware Package by 5150 AutoSport, featuring 100% genuine ARP components. This all-inclusive kit is specifically designed for the BMW Toyota B58 engine found in models like the GR Supra, M340i, M240i, and 440i xDrive. As your B58 build pushes past factory power limits, OEM torque-to-yield hardware becomes a liability. This package eliminates that risk by replacing critical engine fasteners with high-strength ARP2000 or Custom Age 625+ options—engineered for ultimate clamping force, stability, and durability under extreme boost, RPM, and heat. Whether you're building a 700hp street car or a 1000+hp track monster, this kit provides the fastener strength and reliability you need in one professionally curated package. Kit Includes: ARP Head Stud Kit – Choose from ARP2000 (190 ksi) or Custom Age 625+ (260 ksi) for maximum head sealing under high boost ARP Main Stud Kit – Improves block rigidity and crank alignment; prevents main cap walk and fastener stretch ARP Harmonic Damper Bolts – Prevents bolt walkout or failure seen in high-power B58 builds ARP Girdle Bolt Set – Reinforces lower block structure to prevent flex and maintain main cap alignment ARP Flexplate Bolts – Made from ARP2000 for secure, reusable fastening on the ZF 8HP transmission ARP Oil Sprocket Bolt – Secure high-RPM cam timing with superior fatigue resistance over factory bolts
