Those are definitely not the stock springs or shocks. Even stock mine are damn stiff since the truck weighs so much. That thing is in amazing shape, mine is such a beater, beautiful pics as always wicked.
Those are Crazy Nut Racing Rims I believe. Insanely rare and much weigh a lot too. Be careful with them.
What size engine is that?
I love mine more than my Baja. Has one off A-arms but it needs a new engine.
