Try using this email info@diffsonly.com if you haven't but idk of a number they replied to me on email pretty quick so I had no need for a numer

 

I have 80k miles on my truck I ordered master overhaul kits for both front an rear and yukon 4.88 for front and rear. I would recommend not cutting corners. Do the job right the first time with the best products. Then you will have a brand new front and rear axle.

This is a good comparison chart for gears

Thanks realist. Would you happen to have product links? I would like to just find a FULL kit ya know. Like with both ring and opinions front and rear with install kits.

 

Just got an email back from diffsonly.com and I feel like they are pretty awesome prices.

Prices for Yukon 4.56's and Yukon Install Kits...

Front Gears - $195
Front Master Install Kit - $205
Rear Gears - $160
Rear Master Install Kit - $220

Prices do not include shipping.

 

Yukons a little more expensive I got USA standard gears a good bit cheaper

 

Looking at that chart above, I think I will go with Yukon.

 

I personally don't think there's a difference even the ford mechanic that installed mine said there isn't really a difference but it's your money lol

 

Lol I'm sure I would be fine with the USA standard. Lookin at the above graph I'm starting to think that some company put Yukon at the top because they are sponsored by them or something. Something doesn't seem right. But Yukon makes a great product.

 

He quoted me for USA Standard too and I would only save $80. Personally, I'll spend the extra $80 for the Yukon's.

 

I purchased everything individually, from amazon. you can get everything with free shipping from

Yukon and USA standard are made by the same company. Yukon has a higher quality and machining standard. What does not meet the high standard of Yukon gets rebranded as USA standard. For a small cost you are getting the best of the best. Why do think they are more expensive and every diff company sells them. they are the best hands down, any professional will tell you that, and they have a warranty to back it up.

from amazon I got

Yukon 4.88 for Ford 9.75 - $212.24
Master install kit from Yukon - $289.89
Yukon 4.88 for Ford 8.8 reverse rotation - $235
Master install kit from Yukon - $278
Total - $1015.13

This is all Yukon parts and my front and rear diff will be almost 100% brand new and solid
