Product Details
The ARP connecting rod bolt set for the BMW M40 / M42 / M43 / M44 replaces the factory connecting rod bolts with high-strength ARP studs/bolts that clamp the connecting rod caps. Designed for BMW’s M40-series four-cylinder engines, this is a critical upgrade making it an essential upgrade for any high-performance rebuild or boosted conversion. 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.
