Description
Finally a brand new set of 4:22 ring and pinion gears.
This is not a straight drop in replacement. It will take extra machine work to install into your original 4:22 rear end housing but you can be assured it will work properly if done by a professional rear end rebuilder.
This gear set is only for an experienced professional rebuilder. It's not an easy or quick modification.
They are an Oerlikon cut - not Gleeson (like originals.) Oerlikon is a modern method of gear cutting - far superior to the Gleeson method but a little more difficult to set up. The cut of the gear is more “banana” shape, therefore running quieter then the “old” Gleeson equivalent.
Good Used Rebuilt 4:22 Rear Ends are getting extremely rare and will only be around for so long.
If you want the rebuilt 4:22 where it's all ready to install, click below in the related items.
We also have these in a 3:9 Ring & Pinion Gear Set.
