Anyone out there making these? What if any difference in diameter and spring rate are the small block v/s big block tbars?
 
I just bough a set from the Chrysler dealer I went on summit took the mopar number and ordered them
it cost me 180 cad I used p5249157 on my car
 
measure length before you order if there longer on your model, my belv are 41 inches long
 
Hope this clarifies the difference between 72 and prior bars from 73 and up bars including length

I got the 1.06" diameter T-bar from Firm Feel for my 75 Road Runner with 440

I installed the T-bar and replaced the lower control arm bushing and boxed both control arm (the upper arm bushing and sub frame bushing where replaced a year ago)
And i got a bigger sway bar 1 1/8 " from PST a few yrs ago

Before all this upgrade the car was pretty good for handling/comfort just a little soft (40+yrs old bar) and tend to nose dive over road dip/depression

But after all the upgrade the car act like a new car and better!

Thanks RR. Is the ride harsh with that big of a Tbar? I don't want to get something so big that it rattles my fillings out. :)

Hi!

Not at all!
The ride is smooth but firm more like newer car
I got 235/70/15 for front tire and 275/60/15 back no skinny so it's a pretty nice ride

I was afraid too, if I use the bigger bar it will be too rough
I e-mailed Firm Feel and they told me to use the 1.06"...... No regrets!!!
They work great!!
Still use my old 25 yrs old Monroe gas shock for the front nothing fancy it drives and handle great!
 
the guys at firm feel are really good, and nice to deal with. there building me a steering box as we speak
 
Just to give an idea how weak the original T-bar where

OEM/old bar adjuster bolt 13.5 turn

New/1.06 bar adjuster bolt 5 turn
