Tire/Gear Limits? Modification for DEEP gears/tall tires.
Hey Guys,
My neigbor (sucker me) has a 2002 Yukon (5.3 2wd) mud truck running a divorced SCS transfer case (3:1) and rockwell axles (6.72 gears) on 49" tires. Needless to say the speedometer couldn't be more incorrect as it basically has a "20.16" ratio and 49" tires. The gear/tire wizard obviously isn't going to help me out with this. What is my best course for adjusting the speedometer without messing up anything? Transmission controls will obviously need to be heavily modified, but was wondering if it was even possible to adjust the speedometer accordingly. Any thoughts/input much appreciated!
