OK guys are the six cyl torsion bars safe and really worth using on a drag car ? My front suspension is not working from being so stiff , car does not transfer well at all.

they are on sb

BB you might want to find .940 bars(I think thats the
size)... a light bar will have more stored energy so
it lifts for more distance BUT you still need to have
the travel in your front end... cut the upper bump
stops by at least 1/2

mike, I think they are .8 4 0 bar size, that's what I run on the belvedere

I was just taking advantage of being able to answer a tech question,,,lol,,usually do more lurking...

The .840 bars are not offered anymore from MP,,Mancini sells a bigger bar,,,i was able to find a pair from a fellow moparts member.

I know some of the after market suspension places have stuff that is close to the .840 bars,,,

I also cut the bump stop down like you mentioned,,and run the calvert shocks up front now.

see ya at Norwalk Mike,,,,

Doug... thats a definite MAYBE... if I get enough work
done on my new ride I'll bring BIG RED down and stay
in it for the weekend but NO car.... I'll be a watcher
and party

Aren't the slant 6's and 318's the same size bar? I saw a chart a few months back it and from what I remember, they're the same.

Try unloading the bars before switching them out. Back off the adjusters so they just barely hold the car off the ground then see how it works.

I ran my roadrunner that way for 10 years because if I ran it at it's normal height the car would slow down over a tenth and felt too stiff on launch!
It was kind of funny.. I was the only one at NTR that ran their mopar that way back then and I got a LOT of questions about doing it. Two years later there were a number of mopars running that way.

My other pictures at the track won't upload so this is it when it was retired(restored) after four years in storage(divorce).

Thanks guys I don't know if I can loosen them much more and still have ground clearance ! So the 6 cyl bars are .940 or .840 ? Oh I have 5" of travel just can't get it to use it

.840 are the light bars.

The smallest MP bar now available is the .920 bar ( for B bodys that is )

The .840 bar ( if you can find them from MP ) is a race bar..

Not sure what a "6 cylinder" bar size would be,,maybe someone knows...

I have seen some aftermarket suspension places,,,offer bars < .840 and up,,,so you should be able to get what ever you like,,,not sure i would go below the .840 size,,,mine will settle with time,,and i keep the front suspension supported when the car is not in use,,to take the weight off the front.....

I took some measurements awhile back and it seems the 6's and small block B-bodies are .810 or .820

I`m running the 6-cyl bars w/descent results.

Sport 440 ; I'm using the stock 65 Coronet bars now for a b engine. Haven't measured them yet !

I'm running the .820 bars from Firm Feel http://www.firmfeel.com/torsionb_b.htm , and they work awesome. I'm running 29" tall front runners and Afco Double adjustable shocks in the front. With the tall tires I was able to drop the front end and get a lot of travel, also made adjustable bump stops to limit travel as well. Car has been 1.27 60' footbraking.

awesome ! afxcoronet , I'll check them out. Thanks

What about the Mopar "Drag Racing" bars? Any difference? Nice post.
