  • Perfect replacement for my originals.
Style: GM 8.5" 3.73 Ratio
Perfect replacement for the gears that were damaged when I threw a bearing. For the most part, it was easy to install and replace the old chewed up gears. They are heavy and well made! Quality seems to be a priority. I bought the bearing and shim set to go with the gears, now the ride is quiet and smooth. ... show more

  • Notice for GM 12 bolt C10 diff install
Style: GM 12-Bolt Truck 3.73 Ratio
These gears appear to be good quality and the wear pattern looks the best I've ever seen after adjustment. I have a 12 bolt 8.875 GM truck rear in my '67 C10. All 3 of my C10's, '67, '68, '69 2wd trucks had 3.08 factory installed gears. I guess because of only a 3 speed auto trans in my '67 and '68, it was better on the highway. My '69 is a 3 speed manual. I decided that since I built a 383 stroker small block and installed a 3000 rpm stall converter in the TH400, due to the cam profile, I would replace the 3.08 geared, one wheel peel with a 3.73 gear and a Spartan "lunch box" locker. I'm just about to fire this thing up in a week or two. Just waiting on the machine shop to do the final piston fit honing and it ready to assemble, stab it in, hook everything up, start it up, and hold onto my hat. But I digress. Sorry, lost track. Anyhow, changing the gears from 3.08 to 3.73 I obviously had to re-shim my carrier to move it to the left. The factory shims were just about equal from one side to the other. Left being a .230 and right being a .243 thickness. I had to bring my left side to .445 and the right only has .024 gap in order to get my .006-.010 backlash needed for a good pattern. I even had to shim my pinion an additional .030 just to get it right. It's not quite a tight fit as factory, but I don't have a housing spreader and the 3 very thin .008 shims were giving a fit without trying to fold over on me. I don't think .004" is going to give me any trouble. Especially with the Moser girdled diff cover I'm using. Okay, here's the issue I ran into. Being that I needed to shift the carrier over almost a quarter inch, the right side of the carrier was hitting the area just outside and to the front of the bore for the carrier bearing. So, I removed the carrier and used a dremel tool to slightly grind the carrier housing on the four 'corners' where the bearing is pressed on. I took off about .100" on each edge and it then fit like a glove. I got my backlash to .008". Installed the yoke with a new crush sleeve and torqued the pinion nut to 11 in.lbs. Re-installed my carrier and torqued the caps to 60 ft.lbs. and installed the diff girdle cover. Hint to the next guy that decides to rebuild a differential. Purchase some cheap new pinion bearings in addition to the bearings that you are going to install. Grind the inner race of the cheap bearings so they slide over the pinion without being pressed on. This will save a bunch of time and frustration when adjusting or shimming the pinion depth. When it's all clocked in, just remove the dummy bearings and press the final good bearings onto the pinion. Oh, btw, the spartan locker is a pain in the butt to install with the diff housing in the vehicle. If possible, remove it and set it on a bench or jack stands with the yoke facing the floor. It's much easier to articulate the c-clips this way as long as you hold your tongue right. Good luck ... show more

  • Very loud gears but performs well
Style: GM 8.5" 3.73 Ratio
The price was right. This is not a daily driver for me. Good strength under lots of load, pulls well. However, these gears are loud. Didn’t come with any numbers for the pinion depth install as other pinions would. Gets the job done for little money. Pick your poison is all I can say!

  • Gears gears gears.
Style: Chrysler 9.25" 4.56 Ratio
These gears are just fine. They did the job on my 2004 dodge Dakota 9.25 4.56. I’ve driven them for over 50,000 miles and seem to be doing fine. They do make a little noise but that could be because I installed them and I’m not a professional however I’m happy.

  • Decent quality, price, and customer service
Style: Dana 60 Reverse Rotation 5.13 Ratio
Bought these for price and probably should have known better. You usually get what ya pay for. They came with setup paint on them and appear to have been ran for a while; the machining marks are gone from the coast and drive sides of both the ring and pinion gears. We'll see if the seller makes it right, and I'll post an update. UPDATE: after talking with a few friends, they all felt the paint and markings were just to lap the gears together, essentially negating the break-in period. The gears appear to be un damaged and in good shape, and they even set up pretty well. I've never seen a set of gears that were lapped like this before, so I'll update again, once I've ran them for a while. Also, the seller responded to me in less than a day, on a Sunday, which I did not expect. So good on them and their customer service. Good experience all around. ... show more

  • Direct fit
Style: GM 8.5" 3.73 Ratio
2000 silverado 1500. I ran the differential out of oil. The pinion gear and ring gear were destroyed. I took it apart and put in new pinion and carrier bearings along with the new ring and pinion gears. I used a new crush sleeve on the pinion. I used the 2 oem shims on the differential. The lash came out at 10 thousands. The factory spec is 5-9 thousands. The gear pattern is perfect.Right in the middle.Without any pinion depth adjustment. ... show more

  • What a saver!
Style: AMC Model 35 3.07 Ratio
When the pinion gear blew in the rear end of my 2000 Jeep Wrangler AND no one within an hours drive of me had them on the shelf, I took a chance on Amazon's "This fits your vehicle!" and bought these. Two day shipping, a perfect fit (Yukon is a name I know and trust), AND at least $50 less than what the local auto part stores wanted for them (with several days shipping to actually get them!) I couldn't be happier! Thanks USA Standard Gear (Yukon!) and thanks Amazon, for getting my daily driver back on the road in a single weekend, without breaking the bank! ... show more
