01 Lower A-arm info please.

a arm

I believe you are correct. I think they are all 43" ski stance. I have an upper arm if you need a spare, Don't have any lowers though. Check eBay, there are almost always some listed there.

Almost forgot to mention, I also have a 740 big bore / stroked engine for an 01
sno pro if that would be of any interest to you. It is complete with all the electrical stuff and exhaust. It has very little run time on it.

740

I am not very familiar with it either. It was with a project sled I bought from the family of a guy who got killed in a plane crash. It is built from an 01 Sno pro 440 crankcase. Has aftermarket D & D cylinders with an 85mm bore and Wiseco pistons. It also has a spacer about 1/2 inch thick under the cylinders and the stroke measures 66 or 67 mm, it was hard to get a good measurement. The stock stroke is 63mm. According to my math that makes it about 740cc. I called D & D to see what they could tell me about it and said they did make some cylinders but didn't know anything about the crankshaft. I do remember reading about stroker crankshaft kits for the 500 and 600 engines back around 1999 or 2000 but never heard much more about them. I have sent messages to a couple other performance shops asking about it but haven't gotten anything back yet. I plan to list it on eBay soon and will try to get more info on it before I do.

Wreckmaster, I have a 01 440 SnoPro. It has a 144 X 2 paddle track, drop and rolled chaincase, 10 tooth drivers, Boss Seat, C & A skis and a few other extras. It was a very fun sled with the 440, they have close to the same power as a 600. Very good boondocking sled and almost impossible to get stuck and esay to get unstuck even by just one! I went to a 680 twin this year. Good luck!
