K1 Forged And Billet Connecting Rod 131.6mm
K1 offers two different types of connecting rods made from Forged 4340 Steel and Billet 4340 Steel.
Proprietary bolts produced by ARP to K1 specification have asymmetrical threads to equally load each thread when under pressure.
Connecting rods are shot peened for improved fatigue life and are finished in the USA using our state of the art Sunnen hones.
Housing bore tolerances of +/- .000050" (50 millionths) match some of the tightest accepted tolerances in the industry.
The rods have double bridged caps to reduce housing bore distortion and there is no ridge between the blades acting as a stress riser.
Rods are weight-matched to +/- 1 gram and boxed with the individual rotating, reciprocating, and total weights conveniently noted for balancing.
A special wrist pin bushing material is also used with these assemblies offering optimal friction reduction.
K1 Technologies also has the capability to make custom connecting rods made to your specifications.
If you do not see a connecting rod in our catalog for your application or would like special weights or widths,
please contact us and our K1 Engineers can make a custom set of rods built to your exact specifications.
