Like all SPOOL cranks, this is a true billet crank machined from forged 4340 bar stock.
All components, crank, connecting rods and pistons are balanced.
With the increased cubic capacity from the 94mm stroker crank, increases of up to 50% in torque and low to mid range power are achievable. Boost will come on earlier in the rev range and peak power will increase.
CP pistons come with rings, pins and lock. The gudgeon pins are upgraded to 9310 hardened alloy steel with 5mm wall thickness.
We have customers making over 1000 hp with our billet crankshafts
