Carved from 7000 series aluminum--stronger and lighter Reshaped and beefed up--cooler and stronger Taller profile in tail section and no holes below bump stops Non kicked up for increased performance in deep snow! Bomber version has minimal cutouts for ultimate strength For model year 2013 and up XM Lengths: 146, 154, 163, and 174* **Rails are pre-drilled to accept our ULTRALIGHT rail braces. These go under the rear bump stops and bridge the low center section of the rail required by the summit's suspension design. This allows you to maintain maximum rail strength on big impacts without sacrificing skid travel by increasing rail height. ULTRALIGHT rail braces are highly recommended for Summit riders who like to hit jumps and drops!** Rails are pre-drilled for non-reversible scratchers, if you are using reversible scratchers, locating and drilling your own holes for the mounting bracket may be required. Kit includes: 2 rails 2 hi-fax 4 bumpers and hardware 2 tips and hardware 2 idler adjuster housings, bolts, and mounting hardware *XM rails in 154" will stretch a factory 146" Summit Gen4! *All 146-174 rails have the same suspension hole pattern, to stretch your summit, just order the longer set. If your sled did not start as a summit, these will not bolt on and extend your skid. OEM XM rear idler wheels are 8", so to retain stock wheel and axle order rails for 8" wheels. Our 174 T3 rail is only for the factory 174 T3 suspension. All sleds stretching to 174 use our standard 174" rail.
