4.10 Re-gearing - 2025

[CheddarGau]

I wasn’t able to find a shop to install before being out of state, so can’t comment yet. Has anyone else used Yukon rear gears or have a better option? From what I had read, not much difference between Yukon, USA Standard etc..

I'm using usa standard gears in the rear, which are said to be a lower tier than Yukon. They are fine. Noise isn't bad, honestly pretty much the same as the factory gear noise. My pattern could be better, but I haven't had time to pull it apart and re-do it. The rears were 250 or 350 cad (dont remember). Rears super common. I believe Yukon sells the front gears based on when I was looking. Also a wrecking yard in Alberta has the complete 4.10 rear axle if anyone is looking. I ordered the front from them and just used the factory set up and swapped it in. I did install a torsen lsd in the front and a clutch lsd in the rear.

I’ve been told by a few shops that the place of manufacture is the only real difference. Motive from Italy and revolution etc from Korea are the best bets but still 50/50 on noise production.

That’s good to hear - I’m on the hunt!

Salutations Everyone! Anyone know where to get those front 4.10 gears? I feel like I arrived to the party just a bit too late. I checked Amazon, EBay, Summit, RockAuto, JCE Racing and no luck yet. Some say they have back orders available, but I spoke with Yukon and they told me they source it out straight from Spicer, that they were 90% sure that they discontinued it. I searched under “YG D30HD-410L” and under “Dana Spicer 84006-5”; no cigar I feel I’m running out of options. I live in Puerto Rico so 4cyl KJs are nonexistent. Anyone here selling? Or could point me the right way? Much Appreciated

I would Appreciate it very much! I’m so desperate I’m currently looking at a used parts resaler from Spain! Jaja an Odyssey

The rear is easy to find. You may have to check ebay. Amazon did have the front back in January. I would contact various vendors and see if they have them in stock. The Yukon site says back order available. Maybe you order them?

So if the parts come to you for around $1000 (CAD), I think it's worth while. When amazon had the front ring and pinion I think it was in the 1000-1200 range. You can also set the notification on amazon to alert you when they are in stock.

Thank You so Much Cheddar I will get in contact, specially with that last link to see if they have it and compare prices. I was looking at the Spain listing, and they offer the complete assembly of the front differential of a 2004 4cyl for around 700 euros ($800 US dollars) so I may follow that route if they can ship over here. Thanks for shining light!

Yeah if the shipping isn't terrible then it's a good buy. Complete assembly with no hassles.

Here is a place that has it listed for 370 US. Don't know if it is legit but it lets you add to cart.
