The GARD installed on a Tour Coach.

While a bus in operating on a level surface with full air up, the GARD should ride 4" to 5" off the ground, with 4 1/2" being the optimum height. This may be maintained with use of the leveling valve. It should also be in-board of the tire tread edge curbside 1-1 1/2".

When the bus is loading or off-loading passengers at the curb of a crowned road, the sway of the bus to the right should then close the gap to 1 1/2" to 3" affording maximum protection in front of the rear wheels during and immediately after the loading/off-loading process.
