Big Block Chevy Gen. 4 Tunnel Hull "XS" Series Offshore Oil Pan

The "XS" Xtreme Series 4-5/8" stroker oil pans are competition tested and race proven. They outperform all other pans available. Each pan starts out jig formed and precision TIG welded, then an exclusive race proven windage tray is added which prevents oil foaming and crankshaft windage, which helps to build more horsepower. Next a high volume oil pump pick-up with a support bracket is added. The entire pan is coated with a hardened aerospace epoxy to resist stains and corrosion. Designed to clear most front style engine mounts including MerCruiser. A simple comparison of available marine oil pans clearly points out Hardin Marine oil pans are boat lengths ahead of all other oil pans. Run what leading racers worldwide already use - the Hardin Marine "XS" Xtreme Series offshore oil pan.

  • Large 12 Quart capacity
  • Pan rear support spacers provided added clearance to mounting fasteners
  • Heavy duty pan rails are notched to allow 4-5/8" stroke rotating assemblies
  • Welded for durability
  • 1/4" NPT Female Bung for Dipstick 
  • "T" bottom style offers additional oil capacity storage for constant supply to the engine oil pickup
  • Zinc plated exclusive one-piece windage tray and crank scraper prevents oil foaming to build more power than other brands
  • Oil relief in kick out allows added room for long filters and sandwich adapters
  • Fully gusseted high-flow oil pick-up included
