Different Torsion Bars?

Eventually sometime soon I want to upgrade my tires to a 285/75/16, and I read that I may need a crank, which is not a problem. I also read that the stock t-bars aren't the best to be cranked on?

How would class 1 or B torsion bars help more than my stock torsion bars? And where would I get them? To be honest, I'm not sure what bars I have if it differs because my truck is a 4x4 offroad? I've got the money, so it doesn't matter how much it costs. Also, does anyone have a picture of where exactly you crank the bars? The diagram on TRS isn't quite clear to me.

Go with class one bars don't waste your time on b bars you might already have those. The only reason to upgrade to 1 bars it that they don't saga s much.

Where can I get the class 1 bars though? I read another thread here where someone said there was a part number to order from ford, which I would end up doing.

How do you know which bars you have to begin with?

IIRC you have to have the VIN from a Ranger with 1 bars to order them through ford.

There is a code on the sticker in your door jamb. It says 'spr' it should have a 2 or 3 digit code.

If you need the VIN to order the T-bars, here is a VIN for #1 T-bars, VIN: 1FTZR15E91TA84102

"FK" means that you have F rate torsion bars and K rate leaf springs.

F torsion bars have a lower spring rate than 1 or B bars.

You don't need a VIN to order the #1 bars if you have the Ford part numbers:

F67Z-5B326-FB Driver side
F67Z-5B326-FA Pass side

Currently about $75 each list at a Ford dealer, $50~55 each online plus shipping.

Thank you! I'll keep this thread saved so when I decide to upgrade the tires, I'll get the torsion bars installed at the same time, and have them crank em and alignment check and everything at the same time, ha.

Thread resurrection! My truck already has class one bars according the door sticker. And in my opinion it is sagging and sometimes the tires knick the fender well somewhere when four wheeling. Should I get some new class ones and install them, or crank the ones that are already on there?

I'd just try cranking them first before you go out and spend money but im sure you know it will stiffen up the ride quality on the front end.

Alright man I will try cranking first. I have 265's which easily fit with no suspension mods and it still rubs just a tad, which it didn't used to. Yeah the stiffness can't get much worse than it is already, so no biggy.

apply a bit of heat to the bolts if they've never been touched. It will reduce the chance of snapping it because I think they have locktite on them.
