Product Details

The Moroso 21581 is a high-performance dry sump oil pan engineered specifically for drag racing applications. This fully fabricated aluminum oil pan features a 4-stage design that maximizes oil control and scavenging efficiency, keeping the crankshaft free from excess oil to allow the engine to spin freely and achieve its full power potential.

Key Features:

  • 4-stage dry sump configuration for superior oil management
  • Four -12AN female pickup ports for comprehensive oil scavenging
  • Compatible with 153-tooth and 168-tooth flywheel combinations
  • Fully fabricated aluminum construction for strength and weight savings
  • Race-proven design for maximum power output
  • Designed to keep crankshaft clear of oil drag for unrestricted rotation

Dry sump oiling systems represent the pinnacle of racing oil control technology, designed for top-level competition where maximum power and oil management are critical. By using external oil pumps and scavenge stages, this system maintains consistent oil pressure while eliminating oil starvation and windage losses that rob horsepower. The four -12AN pickups ensure complete oil evacuation from the pan under extreme acceleration forces encountered in drag racing.

This oil pan is ideal for serious racers who demand professional-grade oiling system performance and reliability in high-stress racing environments.

I got exactly what i ordered. I went with autoplicity because they had the cheapest price for the royal purple filter i wanted. However 7$ shipping was a ridiculous an it wasnt even 2day shipping. So price of product 5 stars, shipping price 2 stars, deliver time 3 stars.

Everything arrived quickly and in perfect condition.

great price and customer service

Awesome dealer for auto-parts. Fast shipping and they sell good products at great prices! Bought set of club racing brake pads for $15 less than anywhere else on a Saturday and they were here the following Wednesday. I'm in Memphis and it was the week before Christmas. I was very impressed and pleased!

They had the parts I needed at the best price. I needed some questions answered to make sure I was ordering the right parts for a 4 year old car and they were very helpful when I called.

Best price on the internet for my parts. Shipped out the next morning.

Finding my parts on this website was incredibly easy. The prices were the lowest around and I was kept up to date about the estimated delivery date. Order #19058

Ordered a Trac-Bar from Autoplicity, and didn't have any problems. WILL be back!

Easy ordering and when i did have a question they answered right away! best price on the product too!
