Does UT allow more height for higher GVW vehicles?
They do but only to a point here is the excerpt from he inspection manual.
2. Check vehicle lift. (Utah Lift Law UCA 41-6a-1631)
a. REJECT when:
1) Frame height is greater than 24 inches on a vehicle with a
GVWR less than 4,500 lbs.
2) Frame height is greater than 26 inches on a vehicle with a
GVWR of 4,500 lbs. and less than 7,500 lbs.
3) Frame height is greater than 28 inches on a vehicle with a
GVWR of 7,500 lbs. or more.
*NOTE: Vehicle must be on a flat surface and unladened for all
measurements. Frame height measurement is from the ground to
the bottom of the frame and should be taken on the left side of the
vehicle under the driver’s seat. If the door certification plate has
been removed, the vehicle shall be considered to be 4,500 lbs.
So it looks like they only allow for 28" to the lowest part of the frame, however I'm not sure if they would count the extended spring hangars part of the frame or not.
