Upper and lower rod bearings are high quality silver caged.
Trued and welded.
We installed a 10 ball max load bearing on the flywheel side for better strength. The flywheel side of the crankshaft has a lot of stress due to the weight of the flywheel. All other bearings are STD 7 ball quality.
We inspect every crank for proper rod clearance.
Center webs are pinned so crank won't twist out of phase.
This is not a drop in crankshaft case modifications are needed. Case trenching to the depth of .100" will be required.
