I made it far enough down the track to evaluate my truck and i need to increase my wheel speed
i am running 4.88 gears with np435 trans 203 t-case so using the calculator my wheel speed is about 21-22 mph 2nd low side and 33 inch tires at about 7500 rpm from searching past post on here something around 28 would be better if i switch to 4.10 gears that would put me at 27-28 depending on what rpm
what are ratios that can be put into a 435 trans such as a pro fab kit i am thinking that instead of changing diff ratio and then later down the road i change things and make to much power for the stock trans and 203 that i will upgrade so maybe it would be better to upgrade it now instead of a diff gear change
thanks for any help Brandon
