Vehicle Information
Arctic Cat ZL 550 Snowmobile (2000-2003)
The Arctic Cat ZL 550, produced from 2000 to 2003, was a popular snowmobile known for its reliable performance. It consistently featured a 550cc liquid-cooled Suzuki twin engine across all model years, providing smooth and lively power. The primary trims offered were the standard ZL 550 and the ZL 550 ESR, which added the convenience of electric start and reverse. While the 2003 models received chassis and suspension refinements, including the Gen-3 ZR chassis with AWS-5 double wishbone front suspension and FasTrack long travel rear suspension, the core engine and platform remained unchanged throughout this production period. These updates were part of broader enhancements across Arctic Cat's lineup. FAQ:
