HILL CLIMBING

Front suspension
Use soft springs. You want the skis to compress very easily and not transmit any upward force
into the chassis.
Use minimal rebound dampening in the shock absorbers and on HPG T/A shocks, the gas
pressure can be reduced to 200psi.
Center
Use medium spring pressure. You need some track pressure for traction but the front arm must
be able to compress easily to absorb bumps.
The limiter strap should be fairly short to keep front end lift to a minimum. Two to three inches
of lift is plenty. A balance must be maintained between having enough traction and keeping the
front end down for steering.
Rear suspension
end down on the ground.
Track
Use the highest profile track available.
On sleds with less than 80 horsepower use a 121 inch track. A deep profile long track might
actually give you too much traction and the lower HP won't be able to spin the track in certain
conditions.
