Someone on here had a set of race torsion bars for sale not that long ago. I don't know if they sold or not. I'm not sure how you'd even search to find them.
But I know I found them on here.
Firm Feel also sells torsion bars and I think they have some drag race bars. I know they make some fairly big road race stuff. I haven't been to his site in awhile.

I dont really know what im looking for. Should i be looking for a race 6cly bar? What size race bar should i be looking for? Any brand? I dont even know whats available. I don't remember how they rate the race bars but I don't think it was by engine size. Thinking about it I think AndyF has a tech page on his web site about torsion bars. You could also call Dick at Firm Feel.

I just jumped on the Firm Feel site real quick and they have an .820 diameter race bar and an .880 street/strip bar. It would be worth it to call Dick and see what he says. He's a sharp guy. And you could check with AndyF too.

I wouldn't use a skinny bar for a street car, there is just too much stress on the thin bar. It depends on how much track time you do and how sensitive the car is to a thicker bar up front. If it was me I'd use at least a SB bar and maybe a BB bar in a street strip type of car. The heavier bars will control the car better on the street although they might slow you down a bit at the track. Even that .820 diameter race bar? I forget the diameter of the /6 bar off the top of my head. I hope the race bar isn't just a /6 bar with race added to it.

Race bar? What kind of racing? Drag racing usually wants a stock 6 cyl bar and 90/10 shocks so that the front end will come up and stay up for weight transfer....Road racing usually wants stiffer springs than stock and these will cost you ET on the drag strip.
Take care, Rick 68 Coronet R/T 440 & 68 Charger 528 Hemi,and 5 Challengers! 6 cyl, 318, 360, 383, 451

.870 with a DA shock sounds like a great idea. I'll make some calls monday. Dave post what you find. I think my Dart needs bars too, the drivers side adjuster is ran way in and the passengers side not so much. Mine measure .850", 273 2bbl car now has a heavy a$$ R1 block in it.

When to change? When they break. /6 are not that light, it's real close to a 318. I've never heard of a TB twisting that far from normal use. TB are made different than valve or coil springs, almost like a drag axel. Check the sockets in the crossmember for rot or cracks. Use the 68-69 383 bar for a replacement.

My BB added 80# to the car over the SB it replaced. Mostly street car, but i want suspension to work best possible at the track. So the 68/69 383 tb is the best option for this? If you can find a set that's nice,? 340 should be ok, depends on how many miles where on them. My bars for the 69 440 are #895-894 (off build sheet) Can't remember the diameter right now. The SB bars are a dime a dozen, should be easy to find. If street-strip they would be best all around in my book. Aftermarket ones that size would be ok, nothing heavier, it would ride like a tank.

A torsion bar is a spring. Just as with coils, different spring rates (diameters) can be used to adjust how the suspension and how the car reacts in your particular situation. And springs wear out too. More so for a light spring required to store more energy.
If the results don't match the theory, change the theory.

Just sooke with matt at firm feel. He suggests .880 bars for best of both worlds. $325/pr, but out of stock right now. Who else should i call for opinions? Well that sucks. How long before they get some in? I think PST has torsion bars. I can't vouch for the quality though. Maybe someone else can.

Yep. I want brand new. Not used up bars that need to be changed again in another 2 or 3yrs. Magnumforce has .870 bars for $325 as well. Need to give them and hotchkiss a call yet. They are pricey new. I forgot about Magnumforce.

FWIW, OE sizes are 0.83, 0.85, 0.87 and 0.89 and have paint daubs in yellow, olive (green), blue and white, respectively. There's not a huge difference in stiffness between them. By far the most common are the 0.85" bars, which should work fine at the dragstrip. I saw a mention of a reconditioning service on the Firm Feel web site a while back. I don't know if that includes an annealing, resetting and heat treating. If they're damaged they're no good for their intended purpose.

There is a pair of the .870 340 bars used in the classifieds for $40. Still have paint no rust. Temping as i wanted brand new, but that price sure looks good to me.

Temping as i wanted brand new, but that price sure looks good to me. 40 bucks and a bit of shipping sounds like a good deal. I'd give that a whirl. You ain't out much if you don't like it and it gives you a starting point that isn't your old used bars.

Your better off getting a set of used A-body bars.. they have already taken a set and wont drop for quite some time.. any new bar that hasnt been pre loaded will take a set

Ok. Thanks guys. That info is appreciated. Mike, these are used 340 A body bars. 892/893. They are marked left and right. Would the driver side be the left? Yes, drivers side is left.
