Should I fit new torsion bars when doing a suspension lift? (torsion bar truths)

Torsion bar truths...

There is a notion within 4wd circles that the fitment of aftermarket or heavy-duty torsion bars can make your vehicle ride 'harsh'.

The opposite is in fact, true.

Adjusting the original-equipment bars for extra ride-height (or to compensate for additional weight) uses up the components spring action - resulting in a harsh ride.

This is because the adjustment or “cranking” action replicates (and replaces) the torsion bars natural movement.

New ‘beefier’ torsion bars, much better resist the ‘stress’ of the cranking action, nor require as much adjustment to achieve the same level of ride height.

This means that the spring action (and therefore the ride quality) is maintained.
