DANA does in fact make a significant number of gearsets in the US today, for both Light Vehicles (D30, 44, 60, etc) as well as Commercial Vehicles (130, 170, 404, etc).

Ex:
D60 4.56 25127-5X Made in US
D60 4.88 708123-4 Made in US
D60 Reverse 4.88 707475-5X Made in US

Hundreds more are made here.
 
Didn't ProFormance have a thread about all gears are made in China, Korea, and India. Except for Dana.....
You mean like the quote on the first page?

Proformance does some really cool shit. But Its always seems like their "testing" has motives, maybe its just because they type in Australian, but it always comes off one sided, and not just as a "we tested this"
 
No complaints here....I ran cryo-ed Dana gears when I had a Jana678 in the front(onlt way we could keep it alive). But now run Yukon in the 14b's F/R(4.88's), as I don't think there is to many choices of domestic gears for the 14b. Plus there so stupid proof, it doesn't really matter :laughing: :laughing: :laughing: :laughing:

TT, that's some funny stuff! Of course, I've heard of Spicer gears coming out of a Yukon box...
Reminds me of the $1.99 "Surprise Gift" paper bag I saw at the thrift store checkout.


Where do these guys fit into the equation? Anyone have experience?

Company History

Crown Race Gears is a family owned company founded in 2015 by Ben Brazda along with his father Pavel and brother Steve. The concept started when Ben, the owner of Filthy Motorsports, was diligently researching ring and pinion brands and discovered that while every manufacturer claimed to be the best, none could provide any information beyond what their sales brochures said. After a few years of dealing with numerous sales reps and visiting with all major manufacturers, he eventually discovered that almost all of the top high performance gear manufacturers today are selling you the exact same gears.

The truth is that there are only a handful of ring and pinion gear manufacturers in the world with the biggest ones being in Korea, India, Italy, and the US. If you look closely at the marking on the gears, you'll notice that the gear sold by the budget brand will be identical to that sold by the expensive performance gear brand. The more expensive brands normally offer a better warranty, tech support, and service while the cheaper brands will be just a set of gears in a box, yet in the end the performance will be same.

With that discovery, and hopes of possibly bringing a true race gear to the market, Ben reached out to his father, Pavel, who just so happens to be one of the top gear design and gear grinding engineers in the country having worked with many well known companies on private as well as military projects. It took almost 2 years of research, development, setup, testing, analysis, and countless meetings, but the end result was a ring and pinion gear set that is independently proven to be significantly stronger, tougher, and more efficient than any other automotive gear set available on the market today.

The proof of concept showed that the new ring and pinion gears were ready for production so Ben reached out to his brother, an ISO 9001 certified auditor in the aerospace industry to have him develop the production process in compliance within ISO 9001 guidelines. That process, along with lining up suppliers and working out the logistics took another year during which multiple production ready gear sets had been undergoing real world testing in Dustin Isenhour's Ultra4 Car and the Filthy Motorsports 80 Series Land Cruiser.

Having proved themselves in the laboratory, completed a full Ultra4 race season, and survived a year of severe trail abuse, the gears were cleared for production and the company was finally introduced as Crown Race Gears in Novermber, 2017.
Interesting info on their process here: Crown Race Gears | Product Overview

I'm not seeing anything other than 14b gears for sale, though. And Filthy Motorsports hasn't been on here in 6 months. Looks like a startup side-venture with a great website.

That's pretty cool for someone to step out and try and offer a better gear for guys like us. I'm all for more/better gear options and there's a TON of info on that website but not one mention of the actual grade of steel. I was hoping to see some 9310 14B gears.
 
Soooooooo, they are doing a better job of picking out the "Better quality" gears by way of aerospace industry testing? I didn't see on there that they are manufacturing the gears in house? Or they are manufacturing the gears at all....

I may be way off though.

Funny thing I bought 2 sets of Yukon 4.88 14b gears a while ago to replace the ones in my truck. The 2 sets came in the same Yukon box, they were different from each other and different from the ones installed (also 4.88 Yukons) hahahhahhahhah.

They have held up though, so that's cool.
