Anyone on here use one of these aam 74030017 diff covers? They list up to 2014 for Silverado but not sure if something changed after that?

This cover looks effective being that its made by AAM so it retains the same fluid trough that the factory cover has, but adds the fins. 

 

I see everyone in your post mentioning the whole Banks deal with differential covers.  The ones Gale Banks made for rear axles are designed just like the AAM one you are looking at.  An improvement on the factory cover in terms of cooling performance while maintaining the axle manufacturer's splash lubrication design.

Take note of the potential issues with "larger capacity" covers.

Do you have the stock stamped steel Diff Cover still on your truck?

Just looked at the most recent Banks video from Thoroughbred Diesel, Wow! Talk about bling, the cover is larger than your stock cover in order to utilize air scoops which is a disaster in the making, claiming to save fuel due to its weight to HP ratio. Well, what happens when this cover whacks something you run over and especially capturing mud and other debris when utilizing your Truck in its work environment? Bye bye Weight to Horse Power when scooping up mud and debris and how about losing it after you hit something on the road. Like I’ve been saying, nothing has come out of this other than just another marketing ploy on just another product looking for attention.

 

Btw, these covers are copies of oem specs so he can attempt to get contracts with automotive manufacturers, with no proof of anything other than talk. All his comparisons are done with stock Diff Covers which is what each and every Diff Cover manufacturer claim.

 

Good luck to all......

Agree to disagree.  I see engineering (banks) vs. designer items (ats, bd, G2, etc.).

G2 has engineers building complete rear ends, Axles, gears etc from the ground up. Banks too is bling as well but brand new getting into Diff Covers and even he himself says he has no idea what’s going to happen or what to expect but one thing for sure, it’s stupid to make a Rear Diff Cover over hang lower with scoops which invites serious damage from road debris or off roading as well clogging from road debris that’ll add weight and require lots of maintenance keeping it free from debris. To me, poorly engineered for functionality.

I’ve driven through road construction and found caked on clay mud like concrete taking it off so you can imagine what would happen to that

 

To each their own but I’d rather buy and use a well built, built by a rear end manufacturer with tons of experience and know how versus someone wanting to get into Diff Cover sales. Question is, who’s going to be the Guinea Pig?

Watching the flat cover with the plexi window says enough about those rear end manufacturers.  Lack of proper lubrication flow and overfilling of the axle and axle tubes.  So much for being axle experts.

  Maybe so with the manufacturers he’s shown but not with G2.

I do hope he does come out with a better idea and as I hope the American ingenuity keeps growing. I’ll be the very first one to jump on it but not all Diff Covers are square internally. As a matter of fact, my G2 is nothing like the others.

Look very closely, both internal side walls and top and bottom are curved forcing fluid towards the center to flow naturally with the gears. His product doesn’t allow as much fluid capacity/volume which is the reason for it being closer up against the gears. G2 Diff Cover is way ahead of all the other manufacturers based on Banks presumption that the fluid needs to be manipulated towards the gears which is a no brainer, exactly what G2 has already engineered.

      Some Assembly is Required

      Common Sense Assembly   Your driveline is forgiving of the occasional mistake. It will even often forgive the random serious blunder. But it will not forgive a continuous bad habit.      What? Not everything needs to be a five thousand word essay.

      Gas Prices

      By Grumpy Bear · Posted

      We drove about 15 minute east today to visit a friend and saw a steep increase in price in the same county. About 50 cents a gallon steepper.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Grumpy Bear · Posted

      Sure about that? A degree wheel and a dial indicator would lower your degree of assurance in that statement. 😉    It why we have offset keys and dialable timing sprockets. Just say'n.... I've built a few and have never seen one "On the money".

      Tire psi

      By Chuck FB · Posted

      I will admit I haven't experimented much with pressure drops beyond the numbers I put in and part of that is that the numbers I used are fairly low and then found out it would trigger regardless at that 35 psi. Having said that I had tried before had changed the placard pressures and being that I have a 1 ton set to 80 on the placard for the rear I believe it triggered close to 60, the front I don't recall now for sure but thought maybe it could get close to 45 from that factory 60 placard pressure. So I never did figure out if it was a number of psi from placard pressure to the alarm or a percentage of the total placard number as some figured it was like a 25% drop from placard pressure would trigger it. So as to try and answer your question, I believe I set the placard pressure on the front to 47 or so and while I run the front tires at 40, they have dipped below that some if its colder and I haven't put "winter air" in yet and never once have had the front alarm go off. I would say that the answer your looking for is no, that if you set your placard pressure to 45, you have a certain amount of room to drop below that pressure before the alarm will go off.    The pressures you decide to run in your truck, that ends up being what makes sense to you based on what your carrying in your truck or if towing, then have to bump them back up to something that will carry the load in the rear and the fronts typically left at the same pressure. It all comes down to that chart I put the link to and using an accurate roadside scale to be your guide, both unloaded and then loaded to know your minimum safe pressures.    I just wish GM would allow a person to change the readings for the tire pressures to the English system of pounds as I have to look at that goofy metric reading that will never ever jive in my head and will go over and change it just to figure out what they are if need be and then change it back.

      No Software Updates - Old Build

      By TrueBlue · Posted

      That part I understand, that the dealer can do it. But I'm not understanding why updates that were available to the truck since it left the factory, or the dealership originally, would not still be available to it without dealer intervention.   I'm thinking along the lines of recalls. They stay available until they are completed, regardless of whether they are in warranty or not, or in the hands of the original owner or not. Why not updates as well, especially since some of those can be safety related also?
