Further to our ongoing development program, we have redesigned our steel 5.750" conrod. The weight has been reduced from 480g down to 430g, which we believe makes this conrod the lightest 5.750" steel A-series conrod available (weight includes ARP bolts and little end bush)

The MED steel conrods are one of the lightest and strongest ever designed for the 1275 A-Series engine. 

Features include:

  • Double air re-melt steel
  • 18mm little end bush for Omega forged lightweight pistons
  • Fully machined
  • Uniform machine peening
  • Balanced end-to-end within a gram
  • 100% magnaflux tested
  • Laser-etched with our MED logo
  • Fitted with ARP fasteners
  • Supplied boxed into sets with ARP moly and full fitting instructions

What grade steel are these made from? 
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 our temperature controlled inspection department. As part of the design process, we worked closely with ARP to select the best available fasteners.

Why upgrade from 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.

What pistons can I use?
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 Omega forged pistons with 18mm pins.

Will they suit any A-Series engine?
These are designed for all 1275 engines with 1.625" Cooper S size big end journals - so either using an S crank or an MED EN40B billet crankshaft. They will suit all cylinder head arrangements, even eight-ports that can cause camshaft clearance issues with standard rods.
