Product Details

The ARP connecting rod bolt set for the BMW S50B30 / S50B32 replaces the factory connecting rod bolts with high-strength ARP studs/bolts that clamp the connecting rod caps. Designed for the S50B30, the 3.0-litre M-division six of the early Euro E36 M3, this is a critical upgrade where sustained high-RPM operation and hard track use demand the maximum possible clamping integrity. Standard torque-to-yield fasteners stretch permanently and lose clamping load over time — ARP hardware restores and increases that clamping force, helping prevent head gasket failure, cap walk and fastener fatigue.

Available options for this engine:

• ARP2000 — a 220,000 psi alloy steel, the proven choice for performance builds and quality rebuilds

Supplied with ARP Ultra-Torque fastener assembly lubricant. For best results ARP recommends installing to a measured bolt stretch where possible, ensuring accurate and repeatable preload.
