The Stock lower Oil Pan was a compromised design and the “Hump” made by the transverse frame member traps over two cups (two-thirds of a QUART!) of un-drainable, used, contaminated oil in the crankcase at service time.
The "Deep Dish" is for lifted trucks only. Regular GMC's do not have enough space underneath for the Deep Dish.
Exact FIt on 11+ Duramax diesel engine for complete draining
Simple, straight-forward installation. No special tools, cutting, or grinding required
Made from 356-T6 Aluminum, will NOT rust!
