A system for quickly and replaceably securing snow surface sliders to a structural sled runner includes a slide rail fixedly secured to the bottom of the sled runner along both its longitudinally extending straight main portion and its upwardly curved front end portion and a snow surface slider removably mounted to the slide rail. The surface slider and slide rail have mating longitudinally extending dovetail portions to permit longitudinal sliding movement of the surface slider with respect to the sled runner. The dovetail portions of the slide rail and the surface slider are of construction and configuration such that the surface slider is removable from the slide rail by peeling the surface slider laterally off of the slide rail. The surface slider is held in position against longitudinal movement with respect to the sled runner by a releasable fastener proximate only an upper end of the curved front portion of the sled runner. The slider replacement system as described is suitable for use in performing the method of quickly replacing one surface slider mounted to the structural sled runner with another surface slider.
