DOES THE HDK SUSPENSION K-MEMBER HANDLE BETTER THAN A T-BAR SUSPENSION?

Yes, but it has to be more of a complete package approach. A piece of this and a piece of that has much less chance of improvement.

Having done a complete change-out of stock style suspension and steering box, I can tell you that my particular setup feels and behaves like a new car. I like the results achieved by buying this and that. The only thing I might do, is change to a smaller diameter torsion-bar. I also did this stuff to an E-body. The K-frame, idler, Pittman, and center-link are the only original factory replacement pieces.
