Frequently Asked Questions
What makes these better than standard conrods?

There's three benefits - 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.
Which pistons will these work with?

This set features a bushed little end to accept fully-floating gudgeon pins with a standard 13/16" diameter. They are an ideal match for our range of 1.498" standard compression height Omega diecast pistons. They will also work well in forced induction engines with the 18cc forged Omega pistons, as these run a standard diameter pin.
Will these work with all 1275 A-Series crankshafts?

These specific conrods feature 1.750-inch big ends to suit 1275 GT and A-Plus crankshafts.
What torque setting should be used on the bolts?

These should be torqued to 30lb.ft, or preferably checked using an ARP rod bolt stretch gauge and stretched to 0.0050"-0.0055". You will need a 12-point 3/8" socket/spanner to do this.
Do these conrods work in an 8-Port engine?

No, you would need MED steel conrods with Cooper S size journals to clear the camshaft lobes on an 8-port engine.
