Manufactured from 4130 chrome moly steel for strength
Race proven eliminate breakage-prone stock shafts
Centerless ground to avoid stress risers
Heat-treated ends to reduce wear
The stock drive shaft in an oil pump is more likely to fail when it is subjected to the stresses of non-stock usage, such as high volume oil systems, heavy racing oil, and high RPM applications. Failure could be catastrophic to your engine, so upgrading to a Milodon performance oil pump drive shaft could be good insurance at a low cost. It is CNC machined from 4130 chrome moly, centerless ground to avoid stress risers, and features induction heat-treated ends to reduce wear.
