Suspension upgrades

Sparky said
Hey guys, going to upgrade the Cuda suspension. Not sure where to start, or just how far and how much I need to put into it. Been looking at this. 1966-1972 Mopar A-Body TVS Suspension System, Dart, Duster, Valiant, Demon Too much?. Not looking to auto cross, just want good brakes and great handling. Hope to go to OD trans too. Have not searched this thread just yet. Looking for opinions and thoughts, especially if someone has already done this. Been going through all my old Mopar Muscle mags looking for a build I may be able to follow. Getting it done professionally. Will be swapping motors also and possibly looking for a good set of heads to put on a 340. Suggestions, realizing I have not given a lot of info on the motor.

What are your plans for wheels and tires? That's probably the most important factor for deciding what to do with the brakes and suspension. If you stay with 15" wheels that limits your brake rotor diameters and the tire choices that go with 15" wheels will probably reduce the amount of work you need to do to your suspension.

As for the TVS kit, I wouldn't say it's "too much". But it has stuff most cars don't need (like the heim jointed steering links). And it has other stuff you probably don't want on a street car (heims on the UCA's). And it's missing some really important stuff, like torsion bars and shocks.

For what you're describing I'd rather have QA1 UCA's, they have additional built in caster and they’re bushed. If you’re going big bolt pattern anyway then you’re swapping UCA’s or running adaptors anyway so I’d just go with the tubular uppers.

DoctorDiff has all the 73+ disk brake conversions, it’s a good way to go BBP and you still have OE style parts. You can go with 11.75” disks and still run 15” wheels.

PST sells 1.03” torsion bars and there’s a FABO discount. I wouldn’t run anything smaller than that anymore. Even the 1” bars I ran for a bit with 225/60/15’s on my Duster were pretty soft, lots of body roll still.

You can get LCA boxing plates and other nice goodies from @BergmanAutoCraft depending on what you want to do for the other suspension bushings.
