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

im at 100k miles on powertrain would it be wise to do a rebuild on the rear end when I get gears for it....?


what are a good set of gears (brand names) ive got 3.55 but want 4.10's


how do I know if I have a 8.8 or a 9 rear end??? I'm not great on decoding the rear end

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!!
