on stands, you have no clearance, as the ARB is attached along the torsion arm….i.e facing up at about 220 degrees(7 o'clock to 1 o'clock) (from rear of torsion arm (where the spindle is) to the front where the torsion leaves are) the PIVOTAL POINT being , where the torsion leaves are, so the more the rear point of the ARB goes DOWN, the more the front point goes UP
once the bus is on its wheels, the ARB is probably facing up as a shallower angle , maybe 250 degrees(8 o'clock to 2 o'clock) (hence why it clears the brake, rear has come up, so front has gone down


Lower a bus to more extreme amounts…..say for example, the torsion arms are level (270 degrees)(9o'clock to 3 o'clock) then the ARB sits level

REALLY slam a bus, so your torsion arms are facing up at the spindle end, lets say approx 300 degrees (10 o'clock to 4 o'clock) then your getting into dangerous territory as the front edge of the ARB will be heading down at the same angle …sitting lower than the lowest point of your beam and in danger of catching on drains, curbs and pot holes

so if your going really low….dont fit a standard ARB and not expect it to be the 1st thing you wreck (and hope you don't do a lot more damage as its forced to bend , clamped tightly to your torsion arms…ouch !!!!
