This thing looks Killer and is HUGE!
This piece looks amazing! Very high quality part and for sure beefier than the stock pan. The extra capacity will go a long way in the scheduled maintenance on my 2006 LBZ Duramax. Nice thing too, it doesn't hang any lower than the cross member in front of it, so it's still well protected under the truck. It's plenty thick and strong if something does happen to somehow hit it. Up next is the ATS Rear Diff cover to match!
Another Great ATS Product
This deep pan was the perfect finishing touch for my Stage 4 Trans build. Deep pan allows for extra capacity to aid in cooling. The finned outer case helps in that area too, but on the inside of the pan are a series of tall fins that help dissipate the heat even better while keeping the fluid from sloshing around in the pan. Just need to be careful, the pan sits a little low in the frame, without adequate clearance, you could potentially smash it on a rock or something else if driving off the paved roads.
