so im wondering what the ratio is and which diff the fit in? will they fit the 8.8?

Well Yukon makes gears that will fit in pretty much any axle and any ratio.

 

x2. Here's the list... lol... http://yukongear.com/PartsList.aspx?...SpotlightID=23


For the 8.8, Yukon makes 3.08, 3.27, 3.31, 3.55, 3.73, 3.90, 4.11, 4.30, 4.56, 4.88, 5.13, 5.71, and 6.14.

 

oh! so they are a manufacture not the GMC!!!! got ya!

 

Yukon gears are great.. I have 4.56's up front and in the rear.. wish I would have gone with 4.88's or maybe even 5.13's.. maybe in the future though..

 

for 35s what would be better? 4.88s or 5.13s? (3.0L auto, stock had 4.10s with 235/75/15 tires)

 

I would go with 4.88s if I was doing it.

 

ok thanks!

 

ya 4.88's would be great

 

how bout 35 with a 4.0 man 4x4?

 

4.88




4.88 and that 4.0 OHV and a manual is fun!

 

how will this effect my milage and highway drive?

 

putting in gears puts your effective ratio closest you can to stock. puts it back to feeling like stock....driving like stock. mileage figures will be about the same as stock...maybe even better. I'm seeing better than stock and I'm on 5's and kinda large.

 

awesome can anyone set me up with a link of exactly which set to get for my 8.8 and dana 35? i just dont want to get the wrong one.....

Thanks

bump anyone?

^^ditto.

8.8 regular cut(NOT reverse cut)
dana 35 regular cut(NOT reverse cut)(yukon boxes say M35)



BUT.....before ordering....talk to shops around you for the install. Some will not install gears not purchased from them...some will only install one brand of gears for warranty purposes...some require everything to be replaced(bearings, seals, etc)...some won't let you just drop axles off requiring you to drop off and pick up entire truck.....talk to shops around you and get quotes for both just labor and drive in/drive out.

 

Yes, definitely talk with shops before buying gears. Some shops won't touch it unless you buy parts from them. Other will, but charge more and not warranty anything with them (even install screwups) because you bought parts elsewhere.

 

anyone know where the cheapest place to get both sets of 4:88 is? it dosnt matter if its yukon or not i just dont want to break my wallet
and thanks for everyones input

 

well you can buy cheap gears. however you definetly get what you pay for. i ran 5.29's on my runner with 37's and full lock f/r. never had issues or anything. Richmond's and Genuine Gears are good too...

put it to you like this... would you rather buy gears and have them installed more than once... unless you know and trust a mech to do it on the side, its some serious coin

 

I've got a Yukon Posi limited slip differential!!

post #16 in this thread.

Cheapest place I've found and it's where I purchased mine from. And like Dan said, you go cheap, you'll pay for it. Stick to quality, US brands that have good reputations. Like Yukon or Richmond. Cheap chinese crap or even cheap US brands have a real bad habit of howling. I was out 700 grand total for my Yukon gear swap(parts and labor). Quality affordable is out there...just gotta find it.

 

this is true so ill re word my question.... where has everyone found the best bang for there buck?

 

i think the lowest you can go in the front axle is 4.88s

 

ha good cuz thats what i want
