Ski-doo Xp, XS, REV GEN 4 R-Motion Torsion spring set for "big boys" or actually just way better than stock. This set replaces those sagged out factory springs in your XP, XRS, Renegade, Renegade B/C, GSX, and Freeride R-Motion and 146/154 skids giving you a plush ride without the bottoming. These are a much better replacement than the "heavy" Ski-doo recommended replacements that are generally too stiff. These springs fit any 2012-2018 R-motion and are a heavier spring than your sled came with. They still have the soft plush ride but resist bottoming on the big hits. This is a pair (right and left) of torsion springs for a great price.
You also need a spanner wrench to install these or even just remove your suspension without grinding a wrench for 2 hours----check out our spanner wrench on the "tools" page.
