- Comp Cams Hi-Tech Oil Restricting Pushrods
Comp Cams offers these new Hi-Tech Pushrods that restrict oil flow. While the standard Hi-Tech Pushrods feature 0.100'' oil holes, the oil restricting pushrod openings are half that size at 0.050''. These pushrods maintain the consistent Hi-Tech Pushrod features, including one-piece 4130 chromoly material with a wall thickness of .080" and a 60 Rockwell hardness. To avoid confusion, each oil restricted pushrod is clearly labeled with length and diameter.

Features:
- Oil holes are 0.050'' to restrict flow
- Wall thickness of .080'' and a 60 Rockwell hardness
- Engineered from 4130 chromoly, heat-treated steel
- Length and diameter clearly labeled for easy identification
Tech Tip: While restricting oil flow with the pushrods is not the optimum solution, it is commonly used in certain hydraulic flat tappet racing applications where an engine can pump too much oil into the top end valve train and away from the bottom end bearings, cylinder walls, etc.
