Helper bags and cal-tracs?

I would think with the helper bags you could preload the suspension and you wouldn't need the cal tracks? Just a thought.

Not exactly.... He'll need something to counter the minimum qty of leafs. The fewer the leafs in the spring pack, the worse axle hop will be. But.... yes, air bags could help tune an existing set-up by adjusting pre-load.

If it were mine & I was trying to accomplish a quick part-time track truck that can still carry some payload, I'd skip the flipped leafs w/the helper bag & do it right w/a 4-bar.
