Buy from your local Skidoo supplier only, not Gearhead.com
"I bought 2 throttle levers for my 2008 Skidoo Summit Rev XP 154" last March 2016
at the end of the season. I just got around to putting the new one on. It was the wrong part.
Both my adult son and I have the same sleds so I ordered 2 to have a spare.
The parts list shows to the parts I ordered, for the year and sled I listed above.
I called today and no surprise they will not take them back."
