In high output applications, we’ve seen the primary bearing race on 1985-2007 models that is pressed onto the main shaft walk in to the main drive gear and damage it, requiring expensive repairs. This unit replaces the two-piece H-D® bearing with a single sealed unit, similar to the earlier model bearing used successfully for years. Requires the seal listed below for wet applications. Fits all 1985-2007 Big Twins; requires # 872-527 seal and original equipment bearing and race removal.
