Differential Kits, Stronger by Design.....

[Gravel Maker]

Not a sale or a blowout! These are our normal prices. It starts getting a little fake when a sale lasts 2 years and a blowout never blows out, don't you think?.

These are a 1 piece Differential Cover kit, these are only available in .375 (3/8"), we don't make the weaker .25 versions at all, the cost difference is miniscule anyway, the real cost is in the Laser cutting, so pay $3 more and get your Differential Kit in .375. All of our prices are extremely good. And don't forget the Pirate 10% discount, use code PBB10 on checkout. These prices are before the discount!

14 Bolt, Kit cost is $81 and it includes a fill plug and bung.
14 Bolt fully welded cost is $130, Ring only $42

Dana 60, Kit cost is $72, Fully welded cost is $125, Ring only $37
Dana 44, Kit cost is $60, Fully welded cost is $110, Ring only $31

When I said they were stronger by design I am referring to a couple of things. First, we only use A50 plate Steel (the 50 refers to 50,000lbs tensile strength) on everything we make .25" and thicker, we use this Steel because it cuts much cleaner and is stronger. Next, we make these out of 1 piece, they are bent into the desired shape by CNC Brake. Lastly, we allow these to ride up on the ring by .185" (3/16") so as to spread the force of any impact throughout the ring and not just on the welded area. Anyway, if you try hard enough you can break anything but if you can break these we will replace it, forever, Period (only applies to the ones we weld).

We are accepting pre-orders on these now on our website, they won't be available until next Thursday or Friday. I'm not going to try and tease an order out of you by saying these are in limited quantities because thats a bunch of crap. The only way we can price these so reasonably is to make a bunch of them at one time.

With a little coaxing these will fit in a USPS Flat Rate box so shipping is $9.45 each with insurance.

do you have a weld in bung for a fill hole too?

[Gravel Maker]

.....and an Allen plug, this one was a prototype. But, hey thats why we do prototypes, to see what is wrong with the design.

do I get a cookie? ;)

I'm game, I'll definately pick one up from ya. Probably other goodies too, just kinda broke this month but I'll be in touch fo sure

I Have A 44hp Front, Will The Cover Hit The Tie Rod?

[Gravel Maker]

of the ring (of the R&P) so adding 3/8" should give you a fraction over a 5/8", if I remember correctly you have a little over 1" clearance stock.

[Gravel Maker]

What I spoke of was a stock D44, it would all depend on which (if any) highsteer kit you are using and the thickness of the tierod. Do the math in reverse, how much clearance do you have now? Add ~5/16" to the original cover and you are in the neighborhood.

[Gravel Maker]

Link Suspension Brackets and Tabs, Spring Perches, Shock Brackets and Tabs, Panhards', Trusses......Pretty much anything you might weld on your axles. And please, compare our prices!!!:cool2:
And something to think about, Machine bent to make a corner is stronger than welded to make a corner, and less expensive too. Add that to your decision making......

PBB10 = 10%off and we like Paypal, order off the website.

Going to have to reorder before the first ship. Maybe I should ask more? Nah.

BTW, if I used a rubber band to attach a rubber duck to my rig in competition would that rubber band and duck be competition proven?

Will The Cover Also Work With A Rubi 44

[Brandon]

Just a thought for a future idea..

Since your stuff is laser cut anyway I think a slick idea would be to have that top plate cut such that it went all the way to the outside of the ring, and then was cut so some tubing could be welded around each bolt hole. This would make that bottom lip a bit more durable, I don't think I've seen a rig that is actually driven across the rocks that didn't wear through the bottom of the plate. Recessed bolts would rock, and a weld your own style would really rock..

[Gravel Maker]

This is an in progress shot of a cover centered on the ring rather than sitting on the edge of the ring. After this step the cover is tig welded around the bolt holes, then the required clearances are machined, then the bottom is resurfaced for a perfect seal. I do try and stay one step ahead of you Brandon!

What you describe is somewhat alieviated by the A50 steel used in the construction of our rings and covers. 50,000 lbs. of Tensile (think Impact, Wear & Tear) Strength goes a long way, it essentially makes .375 stronger than .5" of a lesser grade of steel. And the covers made of mild steel? Forget it. A50 is not in wide use in this industry due primarily to its' density making it harder on cutting tools.

I say to h*** with the cutting tools and lets make it hard on the rocks!

[Brandon]

well kinda, if you ran that cover all the way to the end the bolts would be recessed so not only would the cover be stout, but them weak bolts would be protected too ;)

Anyway, I will be glad to put your cover to the test - and hopefully soon.

my buildup should start coming together soon..

question altogether by showing you our next step.

The real reason I did so was that what you are asking, though entirely possible, would be very expensive to build. Internal tubes to protect the boltheads, I think countersunk covers that most of the way. The other way to do it would require a cover .75 thick and I don't think I could sell too many $300 differential covers. But hey, keep asking questions, it keeps me thinking.

BTW, if I used a rubber band to attach a rubber duck to my rig in competition would that rubber band and duck be competition proven?

but you could have the one plate all laser cut, then provide the tube not cut to length and the buyer weld it together and grinds it flush.

everybody makes a plain ol cover, only crane makes one with recessed bolts but it is cast and not a DIY money saver kind. If you could get the parts I don't think you could keep them in stock..

[Gravel Maker]

You've got to sell them, and I have dibs.....give me a call today when you get a chance. you know the number.:)
