Starting with a 73 Duster and stock rear suspension, what would you run for bracket racing? This is not an all out tube frame car but a weekend warrior with a fairly warmed up 360 and auto trans.
Problem is that I have no idea what the car will run as I've not run it. Best guess is 13s at BamdimereReally need a ballpark number (et/mph) the bracket intended in order to get some usable Opinions seems to me. 14 second? 13? 12? 11.5? Or 11’s, mid 10’s or quicker? MPH?
Have any of you ever seen a 8 3/4 housing that has Twisted? Where does it twist? Right at the ends at the spring mounts. A pinion snubber prevents this because it holds the pumpkin down instead of letting it fly up and twist the housing.
If you've been running super stock Springs without a snubber and you have never Twisted an axle housing I would suggest you get more horsepower. Because that's the way it works out. Lol
This is how my old school 71 duster was built. It was made to run 11.001. It did so well that for 7 or 8 years straight it was the track champion. Narrowed 8.75 with 4.30 gears. Resplined axles. No back brace. No snubber. The spring pads were boxed in. Mopar long shocks. SS springs. Frame connectors. 6 cylinder T bars. 90/10 front shocks. 12 inch rims. 12.2x31.25x15 W series good Year slicks. Cheetah shifter. 727 with rmvb. 3800 T/A converter. 440 with the old super stock cheater cam. 10.5 compression. Pro parts headers. 2800 lbs. w/o driver. Kim
Has the quality of SS springs improved recently? For several years there were a lot of complaints about the quality.
If 11's were what I was planning on running and had no plans to go faster I'd just run the factory HD springs, clamp the fronts, pinion snubber, /6 bars in the front and a good shocks. If I were planning on stepping up I'd go straight to ladder bars or possibly a four link.

the superstock springs of yesteryear worked , w/o pinion snubber , my old hemi belevedere tore up every pinion snubber we put on it . The springs made in mexico a few yrs back sucked , dont know about now .
I recently picked up a pair of S/S springs, the ones lighter than the 002/003 set. Stamped “Made in Mexico.” It’s the quality of the steel used in the manufacturing of the spring. The springs I picked up from ESPO.com were really nice and they lasted as long as I had the car.
The old school MP books suggestions are tried and true. Yes there’s better. The chassis book even suggests at a certain level that a move away should be made. I don’t remember exactly what time zone it was. Today there are guys blowing that out of the water and I’m sure it was a huge effort to work out the issues in doing so. I’d say it’s probably ot worth your effort to do so.
I see nothing wrong with S/S springs, skinny torsion bars and 4 good shocks for drag racing and even better if there adjustable in which the more adjustable the better. This will do well up to a point and then you’ll have to decide what to move to and the price of the piper to pay.
Like it was said above, the question remains, how fast is it you want to go? (That’s for anybody reading to ask themselves.)
