Forged H-Beam Connecting Rods - BMW B48

Forged H-beam connecting rods for the BMW B48, built for serious boost and high-power builds. Precision-forged from 4340 chrome moly steel and designed to accept genuine ARP 2000 bolts, they handle the loads that crack factory rods on hybrid turbo and forged bottom-end setups. ARP 2000 bolts included.

Specifications

What it does

• Handles big power, with 4340 chrome moly and an H-beam profile that resist flex under heavy boost and detonation, rated to 800-1000+ hp.
• Lasts under load, heat-treated and shot-peened to resist fatigue and microscopic fractures in motorsport and endurance use.
• Spins true, with CNC-machined and fully balanced big ends that maintain crankshaft equilibrium and bearing life.
• Revs quicker, with a lighter H-beam profile that cuts reciprocating mass without losing strength.

Build quality

Precision-forged from 4340 aircraft-grade chrome moly, shot-peened and heat-treated, with bronze small-end bushings and deep locking grooves for ARP bolt stability. Pair with RPM Tuning forged 4032 pistons, upgraded bearings and an MLS head gasket for a complete forged bottom end.
