What are the benefits of using a cast aluminum oil pan?

Cast aluminum dissipates heat better than the stock steel pan. This can help keep your oil cooler, especially under demanding conditions. Plus, the flat-bottom design allows for more complete draining during oil changes.

Does this oil pan come with installation hardware?

The product description does not specify whether installation hardware is included. Refer to the manufacturer's installation instructions for details.

How does the high-capacity design improve oil changes?

The stock Duramax oil pan has a valley that traps over half a quart of old oil. This Wehrli pan has a flat bottom, which allows for more complete draining and less contamination of fresh oil after changes.
