My 67 nova seems to take bumps and dips in the rode very hard in the rear.I just installed new KYB shocks and it didnt change. So..my question is, Can the rear leafs need re-arching to eliminate this? Or maybe replacement..The cat is a stocker..
Adding new shocks would only make it ride firmer, same with changing the springs--unless you're trying to say it's bottoming out the suspension. Is it sagging in the rear?
Stock mono leaf springs and shocks usually ride pretty soft.
