A car shock is going to be way too saft to absorb any reall off/on-raod abuse. You didn't say whether or not it's SPOA or SPUA, but presuming it's like the factory setup just about most of the aftermarket shocks would be an improvement. I have been told that Rancho's are too stiff except for the 9000's as their adjustable. Look for names like Bilstein, Heckthorn, Skyjacker, and Superlift as having some of the better rides around and should be fairly easy to get in Canada. Greg
