My truck has the code FFKK for the t-bar and rear spring code, and i've searched and can't find anywhere on the forum or elsewhere that showed which bar the FF is. Would any of you know which ones these are? My truck has the rear diff 8.8 & 4.10's if that makes a difference.

 

F coded torsion bars have the lowest spring rate of all torsion bars offered on the Ranger. Also available are B and 1 bars with #1 Bars being the stiffest.

 

Its the softest bar. It goes in order 1, B and F from strongest to softest.

 

Ford is so stupid.

Why 1, B and F??

Why not 1, 2, 3 or A, B, C? lol I don't understand Auto makers sometimes.

 

agree lol

 

Yeah that's dumb. Thanks guys I only thought there were two types of t-bars. Would mine be any weaker than the B bars or the #1's?

 

They aren't weaker so to say, they just aren't as stiff.

 

Oh okay darn I wish i had at least the B bars.

 

Oh okay. Thanks darn I guess the F bars are pretty rarin comparison to the #1 and B bars.

 

No Fs are pretty common as well. I have Fs, most 2wd 3.0 Edges do as well.

 

Oh okay, I guess that's because i see a lot of lvl 2s with the #1 bars

 

I replaced my F bars with #1 bars. I couldn't be happier. Only do that if you enjoy a rather stiff ride.

 

ALL level 2's are #1 bar equipped.





F's have a lower spring rate. 1 has the highest.
