ARP Connecting Rod Bolt Kit 201-6301

The ARP Pro Series Rod Bolt Kit is engineered for the BMW M50 24-valve inline-six engine, ensuring superior durability and performance. This kit is a direct upgrade for BMW part #11241713342 and fits 1992-1995 E36 325i, 325is, 325ic, and 525i/525iT models with the 2.5L M50 engine. It includes precision CNC-machined bolts measuring 53mm, with a 44mm version (ARP #201-6201) available for later M50 engines.

Designed for high-performance applications, ARP rod bolts undergo thread rolling after heat treatment, increasing fatigue strength by ten times compared to bolts threaded before heat treatment. This extra step enhances longevity and reliability under extreme conditions.

Built to exceed OEM standards, ARP Pro Series rod bolts are ideal for high-compression and high-stress engine builds, offering unmatched security and performance.
