Best Suburban Specs?

[SafariSS]

I posted this earlier this week, but unbelievably the new 2500 subs only come with a 3.42 rear end. Not good for towing...get an older one.

The barn doors (side-hinged) were discontinued after '02.

Check your GM hitch carefully.

Great info. Moosetags, thanks for the offer to come and see. We may do that although i have a trip coming up this week. I am still confused about the best rear end ratio.

[moosetags]

The 2500 Subs in the the model years you are looking at came with either 3.73 or 4.10 rear end ratios. In effect, the drive shaft turns 3.73 times or 4.10 times to turn the reat axle once. The higher the number the lower the rear end is geared. The lower ratio (higher number) is the better puller, but fuel economy is not quite as good as the higher ratio (lower number) rear end.

In your situation, either ratio will work fine.

It's under control now. I certainly appreciate all of your outstanding assistance. Time to go car shopping! All the best - Evan
