hey guys was looking at the rock hard line of bumpers and sliders...they seem very stout..and heavy..like a 100lbs for just the rear bumper...too much weight with spare and gas cans for the 3 inch evo? should i go 4? will be running 35's and i know the ride is almost legendary... but how about low and slow thru the rocks? also the RH sliders...anyone have them and take a particularly nasty hit? how did they hold up?and LoD...lets not forget them... i'm really more interested in how these perform on the trail when they get hit ...thanks for any thoughts/suggestions..
