hey guys my question is i have a 1998 2500 5.9 litre with a 5-speed trans, i was wondering what rear end gearing i most likely had, and what i would be able to change it to, im looking to lower the gearing just a bit for alittle added towing power, thanks in advance

My truck has a sticker in the glovebox with the axle ratio. There should also be a tag somewhere on the axle cover itself with the ratio. If i'm not mistaken, 2500s with a V8 came with a Dana 60 rear axle for which the factory gear ratio was either 3.54:1 or 4.10:1. Your options for new gear ratios are basically limitless with the Dana axles. If you find you're running 3.54's, a switch to 4.10's with stock tires makes for pretty good low end. Any lower and you'll be hurting your highway performance.

 

open your hood and look up. there should be a tag up there that tells you your gearing. Or, either of the options akyne gave you are good as well.

 

On a 1998, the sticker should be under the hood. I think they switched to putting them in the glove compartment in 2000 or 2001.

 

awesome guys thanks a bunch ill go take a look now.

 

ok guys i took a look i do have a dana, and the ratio is a 3.55, so i assume the 4.10's are the next best option, where do i go about buying them???? i appreciate all the help guys thanks alot.

 

anybody, lol

 

Ring and pinions for the D60 should be as common as bikinis at spring break. Do an internet search and you'll probably get a couple of thousand hits.

 

Finding them is easy on the internet .
Installing them can be tricky though if u don't have the proper tools or ifdon't feel comfortable shop around for a good shop price.

 

IIRC there is an EXCELLENT illustrated write-up on how to rebuild a D60 on either Pavement Sucks or Pirate 4x4.
