  • Arctic Cat M-Series owners can really benefit from a 2 to 3 inch riser block (except for the new 2009 models with the vertical adjusting column). We run into riders all the time that have stock height bars on their Cats and wonder why they are having a hard time maneuvering them properly. If the bars are too low, you don’t have the leverage that you need to throw the sled like you should be able to. The stock M-Chassis bars are maybe the right height for a rider that is about 5’6” tall or shorter.
  • Move the front arm’s upper mounting location in the tunnel (of the rear suspension) down to the lower hole position (leave the rear mount location in the upper position). A pilot hole is there on the inside of the tunnel in the frame-doubler plate that you will have to drill out. This really helps with the heavier 1000s that have the added nose weight, but also helps the 800s pop their nose up out of the snow as well. Let the limiter strap out some also helps in this regard.
  • The 07-08 M-Series Arctic Cats don’t transfer very well. The result is that in deep snow they don’t get the skis up on top of the snow and tend to trench more than they should. On 2008 models you can help this out by reducing the pressure in the rear rail shock to between 85 and 100 psi, or better yet send your rear arm shock to Andy Youngstrom Gas Shock Repair in Menan, Idaho ( or 208-754-4373) and have them do their magic internal shock mods that are really the Cat’s meow. They’ve found some mods that they perform that are sure to impress mountain riders.
  • On 2007 M-Series models, you can re-valve the rear rail shock to soften the compression dampening (send to Gas Shock Repair) and move the rear arm mounting location forward one inch on the rail.  The crossshaft will have to be eliminated when this is done, but it will transfer much better. By doing these mods, these sleds work much better in deep snow conditions.  They are also easier to handle because they will roll up to side-hill with less effort.
