HONDA 400 EX STANDARD SPROCKET HUB

Replacement sprocket hub for RPM Dominator II axles. It is CNC machined from aircraft quality billet 6061 T-6 aluminum. The seal surface portion is made of heat-treated chromoly steel, which is nickel plated and unique to RPM. This steel surface is far superior to our competitor’s aluminum surface, which can become grooved by the seal's abrasion with dirt and grit potentially contaminating the bearings and leading to premature bearing failure.

A new snap ring is included. 

ATTENTION: when ordering you will need the serial number from the center of the axle to select the correct hub for your axle. The middle digits identify the axle and revision. 

Attention: Honda sprocket hubs are a pressed fit, requiring from 2000-4000 psi to install. RPM recommends that a qualified mechanic / shop be hired to install your new sprocket hub.
