Tech Note:

When changing from a 10.25 to a 10.5 gear you must use MKF10.5-A. Short pinion 10.25 housings will need a long pinion yoke to fit the 10.5 inch gear as well. May require new yoke.

Nitro gears are manufactured from 8620 steel gear forgings in the same manufacturing facilities as GM, Dodge, Ford & Toyota. They are precision machined using computer controlled processes, heat treated, CNC triple-lapped and Rockwell tested for hardness. These extra steps ensure excellent fitment, ideal contact pattern and smooth, quiet operation.
