Milodon 21505 - Milodon Oil Pump Shafts

Machined from 4130 chrome moly and centerless ground to avoid stress risers. These race proven shafts eliminate breakage-prone units commonly associated with high volume oil systems, heavy racing oil and high RPM use. Ends are induction heat-treated to reduce wear. Chevy shafts use pinned steel collars instead of plastic.
