NEW DTE DIFFERENTIAL PRODUCT~ Heavy Duty Billet Aluminum Right Differential Side Cover

We are pleased to announce our latest heavy duty Corvette driveline product designed, engineered and produced by Dynotech Engineering Inc., specifically targeted for the 1997-2004 Getrag differential found in the M6/M12/A4 C5 Corvettes' using any gear ratio or any 2/3-series differentials. We've been developing this product for a few months now and have settled into this final design that is scheduled for full production.


Why this product was developed?
The current O.E.M. Getrag differential configuration uses the right side removable cover of the unit to provide the carrier bearing outer race saddle that supports the right side of the carrier, which carries the ring gear. This side cover must provide bearing support, differential sealing, resist deflection and to provide enough structural support to resist the natural tendency of the carrier assembly from trying to "walk" out of the case under heavy stress loading as a result of hard acceleration.

That O.E.M. design is quite strong and even stronger in our aftermarket preparation~ but the current right side cover still has its deficiencies, mainly due to it simply being a "cast" piece of aluminum that often times contains metallurgical porosity, voids and casting flaws within it that can't be seen, which inherently produces a weaker casting from these flaws. We've literally scrapped hundreds of the O.E.M. castings that don't meet our high quality standards just because of this trait alone.

When the O.E.M. casting finally does yield to the stress in high performance applications due to metallurgical fatigue, the negative result is split open side covers, heavy cracks, carrier bearing failures and ultimately complete differential failure where nothing is salvageable. This of course is not only aggravating of having your car down, but is quite costly to repair.

Our product is designed to address and correct all of those inherent flaws that are present in the O.E.M. castings...


Improved Design Features
- Our heavy duty right-side cover is manufactured entirely of aircraft industry grade 6061-T6 billet aluminum using CNC processes for absolute repeatable dimensional accuracy from piece-to-piece.
- Heavy circumference "girdling" of the entire part for added mounting ear strength.
- Extra thick mounting flanges to resist flange deflection during hard launches.
- Improved O-ring groove to eliminate side cover leaks.
- Massively thick bearing race saddles to provide superior carrier bearing support that eliminates carrier walk and bearing saddle deflection.
- Improved internal bearing oiling strategies for cooler differential operation and promotes longer bearing life. (This is especially beneficial to road racers)
- Tighter outer seal fitment for improved seal retention.
- Outer seals are physically screwed to the side cover to completely eliminate any chances that the outer seal can pop out of the cover. (This is also especially beneficial to road racers)
- Removable lubricant deflector that cannot break off like the O.E. parts do.
- Deep bearing race saddle pockets that allow for more accurate carrier shimming for high performance use.
- Improved oil deflector design that funnels larger quantities of lubricant to the bearing faster, while shedding any unnecessary lubricant sooner to prevent bearing oiling starvation under high cornering loads, while simultaneously eliminating seal "flooding" from too much oil feed.
- Heavily radiused corners to eliminate cracking.
- Extra thick main body to eliminate side cover deflection as a whole and to provide the main case additional structural rigidity.
- DTE name and website engraved into side cover for easy identification


This product can be ordered as an option for any one of our differentials we build here or can be purchased outright for the DIY'er and/or for your tuner-builder to install. It will be sold as a kit that will contain a new outer O-ring, outer axle shaft seal, axle shaft seal retention stainless steel fasteners, oil deflector and deflector retention stainless steel fasteners.

This product will fit with any model of differential strut we have ever produced and is *STRONGLY* suggested for anyone who is *serious*, that takes their car drag racing, road racing, DE events or auto-x. We suggest that this product be installed by individuals or companies familiar with the Corvette Getrag differential.

Production of this product will commence next week and the kits should be available approx. 2 weeks after that. Pricing will follw shortly, but the complete kit should fall into the $699-$749 range.

Finally, this product has been in development for quite some time now and it's just another one of our HD Corvette driveline products exclusively designed, engineered and produced by DTE to meet the high driveline durability needs of the Corvette IRS differential owner, both now and in the future. We've got a few other related components in prototype now that will be released within weeks also and we'll never cease in trying to engineer the "perfect part" to meet everyone's needs!

*Photos display the kit contents, and stock vs. our product for both front and backside views.

We're serious about Corvette IRS driveline durability. Are you...???

If anyone has any questions, please don't hesitate to call. (260)407-5455

okay, now we need a billet C6 center section. It could look like a big block with holes in it

 

Here are additional photos of another broken differential that arrived here with the same problem as described in the original post regarding the O.E.M. cast parts fracturing under heavy loads.

wow, that busted one looks bad! I haven't seen any failures like that before, do these fail after the shafts are replaced, or when mostly stock?

 

We've seen failures like this from many different vehicles with many different power output combinations/levels, upgrade options, etc. A natural trait of cast aluminum is that it often begins to fatigue far before it ever yields to fracture, but when it finally does yield to the stress, it does so catastrophically like you see above.

Wow this is a great idea.

 

Necessity was the driver of invention..

 

Looks good. I might need a second job to afford it though.

We tightened up the cycle time a bit in some areas to quicken the machining process for increased production efficiency and further reduced machining waste, so the component now takes a bit less time/material to produce than our prototype cover did; therefore the overall cost was brought down below our intial cost projection stated in the opening post. The entire kit will come in at $649 when in full production.

Since you are an engineer would you please enlighten me as to what loads you designed your billet cover to and what factor of safety you used?

 

Thank you.

 

Does all of that make you feel better now?? Nice try, but put down the physics book and step away from the keyboard... You and most others who do not or can not understand what vector loads we're targeting typically miss the entire design concept of what we've already successfully proven with our products design.

Aren't you late for your Yank support group meeting?

The one irrefutable fact about arguing with a fool is that they will drag you down to their level and then beat you there with experience...

Your predictable fishing for an internet argument will yield no bites here. As far as the rest of your silly comments~ thanks for the comic releif.

Good day.

 

Laughing makes you look bad.

Explaining why you did what you did makes me look bad. Sorry I was interested.

 

Keep fishing, you're giving all our office personnel something to chuckle about. This is great stuff.. Thank you!

Best Regards,
DTE

 

O RLY???????? Please don't alter my wording again because you have it in for me.. Thank you.

 

That is a great photo isn't it?

Those are three very good customers of ours that use our dyno for testing and their looking over the 1007 N/A RWHP they had just made with their car that has a 704 ci Donovan big block/Lenco combination in a 1993 Chevy Lumina tube chassis car. They were quite pleased, so the photo was taken of them for their scrap book and these "redneck dummies", as you so comically put it, have consistantly put that car into the high 6's week after week.
Thanks for taking the time to look at our website!

Is this the same kind of silly statement you made to us a while ago here that said we "couldn't afford" to be sponsors here...

They aren't meant too, as are yours when you stepped into this thread. You know, like when you stooped to calling the owner here a d*ck, a pr*ck and other intelligent names you composed a few weeks ago in your posts, then going back into your posts to edit them after a reply was made to you to change your angle that would better hedge your silly claims about us..

No, not really~ we just choose to ignore argumentative, discrediting agenda, incompetance like yours, because it only wastes time for everyone, however funny it is to watch in action.

We've never stated we're the best at it, thank you for the acknowledgement that our products work and thanks for the sentiment none-the-less. Our products have already proven themselves over the last 4 years, but thanks for re-assuring us with your infinite knowledge that we've built an outstanding product(s).

You must be a young, immature whipper-snapper to be such a fiesty keyboard commando like you are, which makes you quite predictable and the other "redneck" office personnel around here can't wait to see what you come up with next. Have a super day!!!


Best Regards,

First of all, I'm going to laugh along with the crew at DTE about your comments. Secondly, who the hell are you and why should anyone feel the need to justify their designs and calculations on a proprietary product? Are you a customer of theirs, or a troll? Thirdly, go ask around on the various Corvette sites and see if anyone is unhappy with their DTE brace. Please report back with results, and possibly come up with a ratio of happy vs unhappy.

BTW, I also have a degree in Mechanical Engineering, with 10 years industry experience. The only thing I could think of when I read your reply is that you are using this in a condescending manner. Just by reading your comments, you come off as a keyboard warrior armed with a physics book. Your only goal here is to start trouble, and I'll go ahead and give you this ONE warning: Do not reply again in attempt to harass DTE, or your user account will be locked down for a period of time.

Ok....you have a pm explaining.
