.860 King Pin Boss Reamer…Our time-tested tool for sizing king pin bosses.
With 2 pilots included to help you cut the perfect straight hole. Now available is an extension to ream out spindle bushings.
When spindle bushings are cut to the proper size and inline they last much longer.
Remember all of our axles are honed to size so the reamer is not needed on the king pin bosses if you run a Fast Axle!
