I got my first jeep ,a 97 sahara with 4.0 . Problem is the PO installed an unknown lift and it handles like a boat in ruff seas .The shocks are gray and only markings I can find on them is "made in Mexico " Rear springs are gray and measure 11.5 in Front springs measure 16 in .My question is do you think I can get away with replacing the shocks with Bilsteins and leaving the coils ? Another option I am considering is getting a zone 3in lift kit and replacing all the existing , but I'm really wanting the Bilstein shocks . also it does have the skid lowered and I'm not experiencing any vibes but it is definitely a handful . thanks for any opinions .
