Pro-Stock Pro-Mod Dry Sump

Without a doubt STEF’S Dry Sump Drag Race Oil Pans offer the maximum achievable horsepower possible through oil pan design. Obtaining and maintaining the level of superiority is only possible by “out of the box” thinking. Balancing exterior restraints, pan area, scavenge capabilities, and required windage screen area are all dictated by chassis, engine displacement, and RPM range.

STEF’S commitment to cutting edge design is possible due to the close working relationships and trust we have with top Pro Stock and Pro Mod engine builder across the country. The extensive dyno time spent by these teams allows us to focus on oil pan related gains. With this R&D we are able to improve oil flow and scavenging to maximize our customers combination. This unique “one on one “ relationship that we have with professional race teams is why STEF’S is unparalleled in the industry when it comes to oil pan design.

Below we have listed our standard pan configurations. These all include our basic 2 x 12AN female scavenge fittings with optional 3rd and 4th available for your application. Due to the complex nature of these oil pans, please call our engineers at 732 367 8700 for personalized custom service. Mounting hardware is include with each oil pan.
