Who here has change their gear ratio from stock to something else? And how did you like it?
I have a 2003 GMC Sonoma 4.3 4L60 running on 20-in rims front 245/35z/20 rear 255/35z/20
I switch from 3:42 to 3:73 and I like the difference and so far seeing no real different in gas mileage.
Tire Height: difference is. the stock 205/75/15 is 27.1in and the 255/35z/20 is 27.2in No speedometer correction needed Nice.
