I don’t have great roads. And they’re definitely worth the money!
KYB’s are garbage. I used them for around 50k miles on my Challenger with 1.12” torsion bars. Switching to the Bilsteins was like driving a whole new car. I immediately regretted not changing over to the Bilsteins sooner.
I also used a set on my Duster with 1.12” bars. I’ve since changed them out for Hotchkis shocks on the Duster. The hotchkis shocks are a little better with those pretty large torsion bars. Not that the Bilsteins weren’t good, the hotchkis shocks are just a little better with the 1.12” bars.
