Can't do the diff gear ratio's,I now that for a fact for a '02 KJ.

You are probably right on that one. I know that you can do the diff gear ratio in trucks, not sure on some of the other vehicles.

Got the lift installed on thursday. On my way down to the installer I decide to see if the speedo is correct. To my suprise when it was reading 70 my gps is showing 65. This was with the 235/65/17 factory HP tires installed..

After the lift was completed I installed some 245/70/17. I now check the speedo with my gps and it is now correct. Do I still the computer updated or anything else done to it? Or did I just get lucky on this????

The stock speedo reads a tad high, but that is to protect you from speeding tickets wrought from hooning

For proper shift points and whatnot, you really should still have your tire rollout adjusted, but from earlier posts in this thread, it's a crapshoot whether it's possible or not.

Thanks TBJ

I still have my appt with the dealer in the morning. I guess we will see if it can be updated.

Just got back from my appt and the speedo can be updated. They updated it using revs per mile.

Looks like it can still be done on an 07
