This is a complete rear arm replacement that eliminates the T-motion components. Lower scissor machined from billet and the upper scissor fabricated from chromoly. Direct replacement, no drilling or other fabrication necessary.
This will completely eliminate the T-motion action that is standard on all Ski-Doo Summit sleds. Although this kit will make it more difficult to initiate the roll up for some, if you are using the ride technique that we teach at Ride Rasmussen Style you won’t notice any difference. The improvement comes while riding extreme steep terrain. The sled will hold a line much longer, less chance of washout as well as panel out. This is a must have upgrade for the extreme back country rider. SDTMX400-10
