Need Stronger Torsion bars for 73 Dart

I have a 73 Dart Swinger that my son and I are restoring. The Torsion bars are so soft, or worn out, that going over a speed bump will bottom out the front end. I need to get a stronger replacement set and not spend $300+ for them. Can some one help? Thanks.

What was the motor in the car originally and what motor do you have in it now? Just trying to figure out what size you have in there now.

But the new 1" T-bars are like $159 shipped from just suspension. That will be significantly stiffer than stock, but will handle very nice. Not really a bad ride either.

I suspect you probably have totally worn out shocks maybe?
