The Cognito Rear Shock Tuning Kit for Polaris OE Fox 3.0 Inch IBP shocks has been specifically designed to optimize shock dampening and drivability for the Cognito Long Travel Kit.

By offering this kit, Cognito has taken all the guesswork out of valving shocks for long travel. This kit includes parts to tune two shocks. This kit does not include shocks, springs, or common wear items.

It is the responsibility of the installer to ensure the shocks are not too worn to install this kit. For example; shocks used in harsh conditions, such as desert racing, need to be rebuilt a minimum of every 1000 miles. Level of wear based on mileage will vary car-to-car.

Cognito does offer tuning kit installation and shock services for an additional cost.
