VM's Top Shaft with Optional Bearing

For our heavy duty aftermarket top shaft, we begin with billet 4340 aircraft grade steel shaft and fully machine the splines and all required features.
After machining, the new top shaft is sent out for heat-treatment where it is thru-hardened. Upon return from heat-treatment the shaft undergoes full quality inspection for hardness and straightness. This top shaft then has the bearing surfaces precision ground via an in-house cylindrical grinding operation.
It is this combination of superior alloy and thru heat-treatment that yields the most durable aftermarket topshaft on the market.
This item is built in-house by VM to our exacting standards.
Don't get fooled by others offering "hardened top-shafts" or top shafts built from 8620 alloy and then case hardened for superficial surface hardness when you need a thru-hardened top shaft.

For stiffness to resist twisting and shearing unlike any others, our 4340 top shaft is your solution.

This super strong aftermarket top shaft is a replacement for the Cub Cadet (No. 384703R1) shaft.
Application: CUB CADET
