About Spool Conrods

All our conrods are stocked here in Brisbane Australia and we send items nationally and international usually within 24 hours of ordering.

Spool Conrods are tried and proven high performance forged steel connecting rods for tuff Street & Strip engine application.

They are made from a two piece chrome moly steel forging to ensure maximum strength and durability AND come standard with ARP 2000 Fasteners.

Forged Steel rods begin their life as bars of 4340 Steel (high carbon which is far superior to the low carbon 51 series steel used in most OEM forged rods) that pass through a rolling forge die. This process compacts the molecular structure and establishes a uniform, longitudinal grain flow. The bars are then heated to a plasticised state, inserted into a female die and pressed into the near final shape while a punch locates and knocks out the big end bore.

In doing this the grain flow at the big end is redirected in a circular pattern, like wood fibers surrounding a knot, and excellent compressive / tensile strength results. Finally the rod is put through CNC machining and finished to the final specification.
