Leading A-Series engine specialist since 1981
The MED steel conrods are one of the lightest and strongest ever designed for the 1275 A-Series engine. Long 6-inch length for use with short height pistons.
Longer rods alter the basic geometry of the rotating assembly to improve performance. Running a shorter compression height piston then offsets the minimal weight gain of the longer conrod.
Made in the UK, with genuine ARP bolts.
Please see the additional information tab for more detail and recommendations.
Supplied as an engine set of four.
Our conrods are fully machined from double air re-melted 817M40 forgings. All rods are shot peened using an automated process to increase fatigue strength and durability. The rods are balanced end-over-end into matched engine sets and are 100% magnaflux crack detected prior to final inspection by CMM in a temperature controlled inspection department. As part of the design process, we worked closely with ARP to select the best available fasteners.
This set features a bushed little end to accept fully-floating gudgeon pins in the lightweight 18mm design. They are an ideal match for any of our competition-grade Omega forged pistons with 18mm pins.
All MED conrods feature 1.625-inch big ends to suit 1275 Cooper S, MG Midget or MED steel billet crankshafts. We do not produce conrods for the larger diameter 1.750-inch big ends, as the extra weight here does not lend itself to full competition usage.
MED conrods vs standard
There's three benefits over standard conrods - strength, light weight and high quality. H-section steel conrods are considerably stronger than mass-produced standard conrods, which were never designed for high performance applications. Standard conrods can be lightened and balanced, but even then our steel conrods will be lighter and stronger. The highly accurate production process allows for exact build tolerances; you will not find a higher quality A-Series conrod.
