hello to all. does anyone know where to find heavy duty coil springs for my gxt 804? i would'nt mind the stiffer ride but am tired of bottoming out the stock ones hauling deer out of the woods. also, anyone have any ideas about just using vehicle coil over shocks to replace the coils and shocks all together? my cart has approx 5" of lift. thanks in advance for reading, you guys always come through with some great advice.
