You will probably want aluminum knuckles and rear lockouts. I broke my rear knuckles pretty fast. Otherwise the shocks suck but will work at first. Everything else is pretty solid- axial did a great job when they made the kit.
Also, pick up a set of lockers. The Axial sintered metal or any aftermarket will do. The aluminum ones in the kit eat out pretty fast.
thanks you is the 55t novak crawler set up good? and do the rock lizards grip up and also are the foam really solf or would i cut them star pattern or jsut go with memory foam
