Default Lifted the truck and having ABS problems

I was just curious if any of you guys with lifted trucks are having this problem. It seems everytime i make a U-turn or coming off my driveway and turn the ABS light turns on. Any ideas here guys?

Check your wheel speed sensor wiring, sounds like you are pulling (stretching) the harness as you extend the suspension.

That is the first time that I have ever heard about that problem... check if there is anywhere where the wire is zip tied up some where.

Thanks guys. My buddy has HP Tuners so maybe he can track which sensor it is.

I have had the issue if you put a tuner in a truck the abs light will come on if you tune for 35" or larger tires. Calibrate for a 34.75" no problems. Not sure if that helps.
