Default rear end

I,m trying to figure out the spec's on my rear end, I know it's a 3.55 and that's about it..... I'm looking to buy 4.10 gears for my rear diff and would like some help. I still have the two tags on the back of the rear diff cover

Check the axle code on your door jamb sticker and look it up, Or on the tag if it says 355 it's open, if it says 3L55 it's L/Slip

If you have a 4.2L or 4.6L it's a 8.8", if it's a 5.4L, 5.0L or Eco it's a 9.75"

Randy's Ring and Pinion will have everything you need!!

Yukon is a great brand!!
