Oil Pump Driveshaft, Chevy, Big Block, Each
Good insurance at a low cost.
These oil pump driveshafts are CNC-machined from 4130 chromemoly and centerless ground to avoid stress risers. These race-proven shafts eclipse breakage-prone stock units that frequently fail when used with high volume oil systems, heavy racing oil, or high rpm applications. The ends are induction heat-treated to reduce wear.
