I've heard of running Rancho adjustable truck shocks on A-bodies, but I haven't tried this myself. Perhaps someone else has more details?
My '75 4 door valiant had standard bias-plys.They quit equipping new cars with bias ply in 75. I figure they rode on new radials and smaller bars for the 75 MY. They probably realized that they needed a bigger bar for radials and came out with the .85 in ‘76.
Is this plausible, @junkyardhero ? I’m hypothesizing the increase in bar sizes correlating to radial use.

i ran ranchos and carrera back in the mid/late 90's when choices were scant, and *good* shocks were 6~700 bucks easy.I've heard of running Rancho adjustable truck shocks on A-bodies, but I haven't tried this myself. Perhaps someone else has more details?
Maybe they're just dirty. lolI'll check.
anything is possible. the more *likely* scenario is ma mopar trying to save a nickle and doing away with the smaller .830 and just equipping all the slant cars with .850They quit equipping new cars with bias ply in 75.

No, they are clean. I must have mixed up the torsion bar and the front sway bar diameter. It's hard getting old.Maybe they're just dirty. lol
front suspension spec page from my 1976 FSM. A bodies are car lines V&Lreally?
do you have a link or a pic of some kind of literature, because that's the first i've ever heard of that. i've parted a grip of 73~76 cars and never seen anything bigger than the standard V8 bars.
Not buying that one. I'm running .88 factory bars and the original 6 leaf Formula S rear springs with Bilstein shocks on the 66. I definitely don't need bigger bars. I have the original .89 on the 68 383 Barracuda, they work also. Neither sets of bars are going into the trash. One size does not fit all.

Funny, I've driven plenty of cars, from 2009 Challenger, to Porche to Corvette. With 250,000 real world miles all over the country on early Barracudas I see no big difference between any new cars, performance cars, and my 66 Barracuda. The only improvement on my 66 Barracuda from stock 1966 Formula S suspension (original rear springs, sway bar, and torsion bars) are Bilstein shocks, a needle bearing idler arm, and a good alignment. Been running high performance radial tires since they came out, no big deal. Keep preaching your "new" wizbang gotta buy "supposed" improvements. Been there, done all that for decades, and I don't need them thank you. You want to road race or autocross, do what you want. I am just not interested in those endeavors.There’s nothing to “buy”, with radial tires and the physical world we inhabit these cars are substantially undersprung with factory torsion bars. There’s no equation or modern method of determining wheel rates for an application that will tell you your car is correctly sprung with the factory bars and a modern set of tires.
Your car, run it how you want. But your car IS undersprung, and it no doubt handles like it is.
FMJ's were undersprung, too, and there were no options for thicker bars for a long, long, long time....(not until after I sold my hot rodded 5th ave). although there is the alternative to big a$$ springs for handling, which consists of lighter, more moderate spring rates for ride comfort, and bigger sway bars for roll stiffness and cornering. IIRC 90's mustangs used this approach pretty successfully.There’s nothing to “buy”, with radial tires and the physical world we inhabit these cars are substantially undersprung with factory torsion bars.

@Mattax is right, the A’s didn’t come standard with radials. The complete changeover for Mopar was when the F’s replaced the A’s, the F’s got radials standard. And, surprise, they also got a redesigned suspension to go with them to correct the differences between bias ply and radial tire use.
yeah, it's basically two schools of thought. who will argue with each other until the heat death of the universe about which approach is better, more correct or enjoys better advantages.although there is the alternative to big a$$ springs for handling, which consists of lighter, more moderate spring rates for ride comfort, and bigger sway bars for roll stiffness and cornering.

So I’m starting to order parts to rebuild and improve the suspension on my 1973 Duster build. I had a set of the early days of the Blistein shocks redone by Hotchkis on my Cuda and Charger and loved them. Made the KYB’s on there prior feel like worn air shocks in comparison. 10 years later,I want that same quality, but not the $600+ price. Is there any shocks similar to the Blistein quality but at a cheaper price? Love you know what you guys have used.
sorry, noThanks, I have wondered what torsion bars were standard on the 76 Police cars that came with factory front and rear sway bars. Does it give the diameter of the front sway bar also?
