ARP Hardware Pack for BMW S58

BMW S58 Complete ARP Engine Hardware Package – All-In-One Strength for High-Power Builds

Upgrade your entire bottom and top end with the BMW S58 Complete Engine Hardware Package by 5150 AutoSport, featuring 100% genuine ARP components. This all-inclusive kit is specifically designed for the BMW S58 engine found in models like the G80 M3, G82/G83 M4, X3M F97, and X4M F98.

As your S58 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 S58 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 8HP76 transmission
• ARP Oil Sprocket Bolt – Secure high-RPM cam timing with superior fatigue resistance over factory bolts
