i notice you guys are talking about 285s im assuming 285/75/16 roughly 33 inches is a 3 inch lift all ya running? over here apparently u need 4 inch lift i always thought 3 inch would be plenty providing nothing rubs.... 16x8 wheels with ET+25mm offset
The SLABS generates and sends a speed signal that is taken from the 4 ABS sensors. When you change the diff ratio, the driveline speed stops matching what it expects to see at the axle because of the diff change. If you use a speedo correction unit on the speed output signal at the SLABS computer it will correct this. BUT when you are doing this, you're not correcting the speed of the car, you are correcting what it should see because of the diff ratio change - this is important. So, to gain cruise control back again, correct from 3.54 diffs to 4.12 diffs. If you're running 285/75-16 (33's) then your speedo will be accurate. To do this you will need to use a pretty specific speedo correction device that needs to pass through the baseline diagnostic frequency, which most do not do. See this article I wrote about 17 years ago for fitting and a SCU that works.
