Banks Ram-Air Diff Cover & CoolRunner Oil Pan on GMC Denali

“I love working with great products!” says Benny at STP Diesel as he spotlights a GMC Denali getting Banks upgrades. He showcases the Ram-Air Differential Cover and the CoolRunner Oil Pan for Duramax, complementing its “Complete oil drain, no sludge buildup, and cooler temps with the fins.”

Why It’s Better:

  • Ram-Air scoop design
  • Adds 2qts oil capacity
  • Allows full oil drainage

00:00 [Music] What’s up everybody? It’s your boy Benny here at STPO, and here we go again with another quick episode of some shop action. Let’s check out what we got going on. I just got word that one of our techs is actually doing some Banks Power accessories on a very, very nice Silverado. I’m sorry—Denali. GMC Denali. Same same, but different. Check it out.

00:21 Boom. Look at this beautiful truck. Very, very nice. We’ve got the differential cover from Banks Power right there—very nice. You can see it’s got the fins, the nice bolts, the drain plug, even a sight glass right there, plus the fill with vents.

00:42 But the highlight of this video is this bad boy we’ve talked about before: the lower oil pan for these Duramaxes. Better drainage compared to the stock one. You can see the stock design is not ideal versus this one, which has fins across for extra cooling, plus a big drain plug.

01:22 Looking inside—you can see the fins in there. Compare it to the old one, and there’s a big difference. With the stock pan, oil collects at the bottom and you don’t get a full drain. This Banks design allows complete drainage, preventing sludge buildup.

02:00 With the fins and airflow, it also helps keep the pan—and your oil—cooler. Better temps all around. My guy Pete is working on this install. For this job, you do have to drop the front diff a little for clearance, which he’s doing now.

02:17 You can see we don’t just remove and reinstall—we prep the surface of the block and the upper pan before fitting the new lower pan. Very, very good. Love working with great products.

02:35 Like always, thank you guys for all the love and support. If you’ve got questions on any of the products we show here on our little show, give us a call or message us. I’m always willing to help and answer questions as much as I can.

02:52 Y’all be safe. Peace.
