Can someone tell me where to read about gear changing? I'm not sure I have to do it. On a 2000 Suburban LS 2WD, changed the tires to 33's with 17" wheels.

If your stock axle ratio is 3.73 then u dont need to change gears for 33's

where do I look to find that out?

glove box has a bunch of codes listed....look for GT4(3.73) or GT5(4.10)

 

[Slvrpismochevy96]

your glove box, u will see a list of codes, you will have to find a website that tells you what each code means, you most likely have 3.73 meaning you dont need new gears but it wouldnt hurt to double check

Gt4 -- Axle Rear, 3.73 Ratio
Gt5 -- Axle Rear, 4.10 Ratio
Gu4 -- Axle Rear, 3.08 Ratio
Gu5 -- Axle Rear, 3.23 Ratio
Gu6 -- Axle Rear, 3.42 Ratio

3.73's and 33's, you shouldnt notice that much power loss. Oh yeah, where are you in Cali?
