Hey Maurice, Blue Ox doesn't have a torque spec recommendation for the U-bolts of the Immobilizer part # BX88224 that you referenced and instead they just state to "tighten the whiz nuts firmly". Which if like me you didn't know what a whiz nut is...it's a flange washer that is serrated on the bottom to resist backing off.

So basically using standard hand tools just get them tight and you'll be good.
