Heavy duty rail kit for your Matryx & Axys Chassis SKS 146 featuring the IGX rear suspension. Our bomber rail series is designed as drop in replacement rail with minimal cutouts for maximum strength. All rails bolt in place of stock rails with no modifications needed. Our SKS 146 rails are design with NO kick up in the rear to help put the max amount of power to the snow and get your SKS farther. Kit Includes 2 rail beams, 2 sticks of hyfax and a hardware kit (new tips, bump stops, adjusters, and necassary hardware.) Rail kits are designed for 8" rear wheels which can be found in the same section you found the rails. Our 155 rails are designed to bolt into the OEM suspension and stretch it for guys who want the additional flotation of the 155 but plush ride of the IGX suspension.
