It'll put more wear on your ball joints, especially when you turn, but it doesnt affect steering. Torsion bar cranks also limit suspension travel and increase spring rate.

Someone please correct me if I'm wrong but a t-bar crank has nothing to do with spring rate, it's all about geometry. First off, the only way to change spring rate would be changing out t-bars for different rated ones. A t-bar crank isnt putting any more tension/pressure on the bars than stock ride, it changes the angle at which the pressure is applied to them. Moving that angle downwards lifts the truck and causes a stiffer feeling ride.

I'm not all that familiar with the geometry of our rangers so I'm not sure that increasing the height does or does not increase pre-load.

Spring rates for a torsion spring are usually linear. Meaning they climb very smoothly in a 1:1 ratio as the spring is deflected.

Provided that the torsion spring is in a freely rotating state on a ranger? And that you've not added weight? It should give the same initial resistance. As well as the deflection rates being the same.

How the hell does it change spring rate? It doesn't.

Cranking bars limits downtravel...it still has uptravel. It firms up the ride because of losing downtravel.

The only thing I will add here is that if you adjust your torsion bars, you will need an alignment

IMO the camber in stock form is too much. I've done a mild 1.5 turns to my truck. I rotate the tires every 8-10k and the wear is perfectly uniform on all 4.

I think some guys here have checked out with up to 5 full turns. A checkout is still good though.
