JIMS® has integrated the strength and stiffness of the genuine Harley-Davidson® Twin Cam® crank pin and bearings into their Evo crankshaft assembly
Each flywheel and shaft is forged as a unit to maximize stiffness and reliability
“H” beams 4340 chromoly connecting rods are used
The Evo crankshaft has some limits when ran at high rpms in powerful engines. The taper-fit crank pin flexes at high rpms and can often shift, even in normal use
