what do number 1 torsion bars do for a 2001+ 4x4 ranger? mine is a 2001 with cranked t bars and i was wondering if it helps front end sag. im thinking about putting a custom winch bumper on it and wanna keep my current ride height. how do i check to see what i currently have?

 

+1 bars are stiffer therefor give you a stiffer ride. If you are going to do a custom winch bumper and a winch I would get them if you don't already have them. To tell if you have them or not, look at your door sticker. Where is this door sticker I speak of? Drivers side, by the door jam.

 

what do i look for on the door sticker

 

On the bottom of the sticker there will be something that says "SPR" below that will be something like "BK" (that's what mine says because I have B-bars). Go out and read yours and then tell me what it says. 99% sure you have b-bars. But I don't have any info on your truck.

 

So what does 1K mean then?

 

That you have #1 bars.

 

1 is your front bars, k is for the rear pack

 

Oh yea, thanks Carl. I should've mentioned what the second character on the door sticker meant.

 

Carl ive got 1K so looks like i already have number 1 bars. sweet. that being said how about the rears? whats the specs on a k code spring? and would it better to get exploere springs and swap? Rangercrazy07 and i put explorer springs on his ranger and i couldnt tell any difference in the spring height between the ranger and explorer packs. the difference was in the leaf retainer clamp locations

 

Here's a summary of the springs that were listed for TB Rangers in 2003. Other late models are probably similar:

Torsion bars
(label code / combined capacity / nominal bar diameter)
1 / 2900 lb / 1.09"
B / 2710 lb / 1.06"
F / 2510 lb / 1.03"

Leaf springs
(label code / combined capacity / leaf pack thickness at axle / number of leaves)
C / 2750 lb / 1.82" / 4
F / 2600 lb / 1.64" / 4
K / 2550 lb / 1.60" / 4

 

mike mine has the A3 under the SPR code on my door idk if we can swap the packs but lets look into it
