Gear swap 1/2 done. What drives speedo ?
I am switching out gears from 3.73 to 4.10. As some of you are aware, I bought a complete 14 bolt sf rear end with new 4.10's in it. I haven't done the front yet, still has the 3.73. Need to wait for the next paycheck [img]images/graemlins/burnout.gif[/img] At 1900 RPM with the 3.73, the speedo used to be at 65 mph. Got on the highway this morning fully expecting the speedo to register different with the 4.10s in the rear but the speedo still said 65 mph at 1900 rpm.
Can someone explain to me why?
