I've got a 2000 GMC Sierra rcsb with the 4.3l v6 and stock (3.42) gears. I daily drive it and live in an area that has a lot of hills, but I also do a decent amount of highway driving. The truck has to downshift into 3rd and sometimes 2nd just to get up the hills, and I was wondering if a set of 4.10 gears would solve this issue. The only mod my truck has is a Magnaflow cat back. Suggestions would be appreciated! Thanks! :chevy:
4.10s would def be a great investment
4.10s and a tune would definitely be a good choice.
5.3!!!!! nah.. A tune would be my first thing I did. I wish I had my 3.23s back honestly. 4.10s would certainly stop the downshifting. I have 3.73s and mine hardly ever does it, unless I am going up a huge hill. If I had to choose another ratio for a 2wd, it would be 3.42. I would love to have 3.73 or 4.10s on a 4wd on 33s.
If it doesn't down shift alot keep what you have, if it does then 3.73, 0r 4.10's.
Put in third on the hills like you would while racing and wait til u can 6.0/80e/and good gears swap
Thanks for all the input! I figured the best thing to do for the time being would be to shift the truck into 3rd on the hills. Everyone I know that drives one of these trucks with the v6 has the same problem and complains about how underpowered it is. The only reason why I bought a truck that had the v6 is to save money on insurance. Hopefully in the future I can get my hands a v8 truck!
Buy a w/t with v8 n yull be fine lol.
Thats what i do n i get 15mpg cuz of that one hill in castroville.Quote:
