The I-Beam Connecting rods for BMW 3.0L N55 are built from the finest raw materials 4340 high tensile steel with a specially optimized shape for high performance and extreme durability. These feature “straight cut” pin end for increased durability, so they can only be used in conjunction with aftermarket pistons. The bushings are made from AMPCO 18 material, for excellent resistance to wear and fatigue and have radial groove acting as an oil reservoir. They are shot peened to relieve stress from the material and multi-stage heat treated to increase rigidity. The tight tolerances in the production process, ensure a perfect fitment while optimizing the oil clearances. Bend and twist is tightly controlled.
Each rod includes ARP 2000 cap fasteners that are rated at 220,000psi, optional ARP L19 material 260.00psi available as an upgrade and the whole kit is supplied with ARP moly and full fitting instructions.

Additional machining processes

• “Straight Cut” Pin End – Suitable for aftermarket pistons
• Dowel sleeves for perfect fit and accurate re-assembling
• Lipped Cap Relief for improved big-end integrity at extreme application
• Grooves in Thrust Face for weight reduction

Technical Features of ZRP Connecting Rods

• I-Beam Shape for extra rigidity
• Two-Piece forging for great strength
• Shot Peening for improved fatigue life
• Magnaflux Inspection guarantees that the consistency of the forged material meets our high-quality standard
• Double ribbed caps for added support
• Multi Stage Heat Treatment for maximum strength, dimensional stability, and fatigue life.
• CNC machining for superior tolerances, precise as much as 0.0002″
• Center to center is maintained under .001″ tolerance
• Finite Element Analysis (FEA) Computer generated stress analysis of con rods
• Optimal balancing for weight matched sets of ± 1gram

Horsepower range for these rods is 175HP. per cylinder with ARP 2000 fasteners and 200HP with ARP L19 fasteners

BMW 2.0L M10 2002 H-Beam Connecting Rods are manufactured from 4340 high tensile steel and are designed for high performance and extreme durability. The bushings are made from Aluminum – silicon/ bronze Aluminum – silicon/ bronze material and have radial groove acting as an oil reservoir. These rods have “Ribbed pin end” that minimizes pin end distortion under heavy inertial loads while saving excess weight. They are shot peened to relieve stress from the material and multi-stage heat treated to increase rigidity. The tight tolerances in the production process, ensure a perfect fitment while optimizing the oil clearances. Bend and twist is tightly controlled.

ATI / PCE super damper installation kit for BMW M50 / M52 / M52TU / M54 / S52 engines (ATI / PCE super damper not included)

Main features of the kit:

    CrMo tool steel crankshaft hub to be used with ATI or PCE super dampers
    Lightweight 60-2 trigger wheel made of high tensile Domex steel (except M52TU / M54 / S52 kit with trigger at the back of the engine block*)
    ATI / PCE super damper shown in the pictures not included
    A/C pulley not compatible with the kits
    Check/adjust the ignition timing after installing
    Underdrive alternator pulley recommended in addition of the kit (click here)

    Comes with mounting hardware and of course MRT Engineering decals

Why do you need one?

If you're building a serious horsepower BMW engine, here's a proper solution to replace the old cranky damper wheel! No more broken harmonic balancers, loosen up crankshaft bolt or oil pump issues, a precise crank signal due to undamped solid trigger wheel. ATI / PCE super dampers are rebuildable and can be tuned with different hardness o-rings.
Does it fit my car?

The kit can be used in BMW M50 / M52 / M52TU / M54 / S52 engines in addition of ATI or PCE super damper shell. See available variations.
ATI #917071 or PCE291.1082 super damper shell and longer 6PK1600 belt required for M50 / M52 / M52TU / M54 / S52 engines
