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!
