Performance Dooly is 31% Lighter and More Aggressive – Woody??s new Slim JimTM Dooly. The original Dooly was designed to reduce the front skis jerking as they hunted for the track of the snowmobiles that had gone before. This reduction in front end darting allowed you to regain confidence in your riding abilities because you could trust your front end control traction. Assertive riders need to be able to read traction as they maneuver through changing trail configurations and ground conditions. The new Slim JimTM Dooly embodies the anti-dart and adds superb cornering control. The Slim Jim enhanced cornering capabilities allow you to take it to the edge of traction and feel comfortable enough to bring it there and back when and if you want to. That level of riding can only be achieved by those who are able to trust their traction. The Slim JimTM Dooly is available in 4??, 6?? and 8?? of 60o turning carbide for Arctic Cat, Polaris, Ski-Doo and Yamaha snowmobiles through the Woody??s runner line.
