"The KYBs will ride rough" Others have said that too. The KYBs are said to be adjustable, right on the box, if they ride rough, won't the adjustability help with that?
KYB’s are not adjustable. And no. KYB’s are hot garbage.
I say that after running them for 10’s of thousands of miles on my Challenger before upgrading to RCD Bilstein shocks. It was like driving a different car, a night and day kind of improvement with the only change being the KYB’s going in the trash where they belong.
KYB’s are a kind of band aid for guys that want to keep the original torsion bars. The combination of a really soft torsion bar, with a really stiff shock, results in a ride that feels somewhat “normal” in fairly basic driving conditions. Handling performance remains trash, because neither component is doing the job it should be doing.
But paired with a torsion bar of an appropriate size for a modern radial tire, KYB’s will rattle your teeth out. And give lousy handling too.
