I purchased a OEM 136 extension kit from Polaris and installed it two years ago. This is the second season. My stock suspension was a 121 Edge rear with Fox PS shock. 136 ripsaw 1 1/4" track with 150+ studs, 1 1/2", down the center. The suspension has front limiter straps only with just a series of holes. The problem I'm having is the extreme weight transfer of suspension under power. I am fairly big and as I'm riding I can't keep the skis on the snow, which is great for drag racers but not real good for river running and trail riding. The ride and the traction is awesome and well worth the money spent, but I have to be able to get this sled to handle. I have not found any information on the adjustments on these limiter straps. Has anybody done this conversion, and if so, did they notice the extreme ski lift? Suggestions or experience would be helpful. P.S. This machine has C&A Pro skis with 9" carbides. I don't necessarily see a push. It does turn in the corners, but you cannot turn under power. You have to let off, and this plays hell with headlight adjustments in the dark. I can give you more information if you have any more questions.
