We developed a drop and roll for the Polaris Matryx and Axys Chassis. This drop and Roll moves the driveshaft back and down 1''. This gives a much needed additional inch of clearance in the front of the tunnel.
With a series 9 3.25 track and 6t 3.5 pitch drivers there is 3/8'' of clearance. This clearance is marginal at best. We know that the track balloons at speed and will actually come off of the drivers in many scenarios. This has been proven over and over again because we've all experienced track ratcheting. If all we have is 3/8'' of clearance (without any ice build up) and that track moves away from the drivers as little as 3/8'' we will have a hard contact. A hard contact is a performance killer. You spent a lot of money on getting 180 hp only to reduce the efficiency with marginal clearance.
There are many benefits to dropping and rolling the driveshaft.
- Improved efficiency using larger drivers.
- You thought putting big wheels on the back was cool, why not put big wheels on the front too, our drop and roll is designed to use 7 tooth 3.5 pitch drivers or 8 tooth 3.0 Pitch and a 3.25 lug track.
- Improved attack angle.
- A shallower or less steep attack angle allows the snowmobile to get on top of the snow better and faster.
- More clearance and proper snow evacuation.
- Tangency between driver and rails.
- More driver tooth engagement
We will be using TKI CNC gears and belt drive parts with both options.
We have a couple options
- A fully CNC Machined side structure, belt guard, adjuster, gears (any combo), clutch side driveshaft relocator.
- Use of stock side structure. We modify the stock side structure welding in a billet piece that moves the centerline of the driveshaft, billet clutch side relocator, and TKI belt drive components. You will be responsible for bottom gear/belt protection. There will be $150 credit given when a non-damaged side structure is returned.
