Just got my Gripper skis for my 22/XC/650/137. My dealer ordered them, $210.00 each. Pro steers sucked in the 8' of snow we got in N.W. Ontario last winter. Also just received wide rubbers from Source Innovations in Calgary. $43.00 a pair plus Canada Post shipping. Way cheaper than Dura Pros. Lots of talk about different carbides. Most were $130.00 to $160.00. Found Polaris 6" carbides for the gripper ski. $99.00 a pair. Polaris part # 2877880. Dealer also got these in for me. They are made by Woodys and are a 3/8" square host bar with hard surface weld on either end of the carbide. This is Canadian $. And my dealer knocked 10% of the skis and carbides because I snowchecked my sled last year. Got that sled Jan.20/22. No Gripper skis until June. Sure hope we get that same snow next winter.
