Duane, this oil pan doesn't have a stabilizer built into it. What it has is a nub on the bottom of the pan where you can bolt the Alloy Art stabilizer instead of using a 'cage' as is required on the stock oil pan. If anyone has the True Trak or the Ride Str8, or any other stabilizer, except the Alloy Art unit, they will not be able to use those units with these pans. This pan prevents access to the oil pan bolts as they are no longer exposed as before. I wonder if Alloy Art contributed to the design as you will be locked into their unit if you use this pan and want to run a stabilizer bracket.
I have a lot of respect for Bert's products, but in this case I think they have come up with a solution and are now looking to create the problem it solves.
I believe their description of how the stock pan circulates is intentionally over-simplified to make it seem like there is a problem with the design. While it is true both inlet and outlet are at the front of the tank, the internal baffles route the oil to the rear of the tank before it can make its way to the front and return to the engine.

Chief, you took the words right out of my mouth. They seem to be implying that the hot return oil is just dumped into the stock pan right next to the pickup. As you noted, that is not how the stock system works. The real difference is the additional quart of oil and the larger surface area of the pan, both of which will contribute to reducing bulk oil temps. The additional quart of oil is something I've always thought would be a good idea on a Harley, but I don't think I'd pay an extra $500 for the privilege of adding that capability.
