Matching Torsion Bars, Leaf Springs and Shock Absorbers

KYB gas-adjusts are hot garbage. If the price is a problem and you really want to run cheap shocks run the OE replacement Monroe’s or Gabriel’s, they’re both better shocks than the KYB’s and cost less.

Bilstein RCD’s are great shocks, so are the Hotchkis Fox shocks (both adjustable and non-adjustable). I haven’t personally run the Viking adjustables but I’ve heard great things about them.

Tossing the KYB’s I had on my Challenger in the trash and replacing them with Bilstein RCD’s might still be in the top ten best modifications I made to my Challenger. Definitely the easiest, tossing the KYB’s made it a whole different car from a ride quality standpoint.
They run stiff. I kinda dig it. The Monroe and Gabriel's I've ran on my old 66 Sat. Eh....
