Vehicle Information
Arctic Cat ZL 500 Snowmobile (1998-2003)
The Arctic Cat ZL 500 snowmobile, produced from 1998 to 2003, was known for its reliability and trail performance. It was powered by a consistent 497cc liquid-cooled Suzuki twin engine across all model years. This model was positioned as a solid choice for snowmobile enthusiasts seeking an agile and responsive machine. The most significant evolution for the ZL 500 during this period was the introduction of Electronic Fuel Injection (EFI) around 1999 or 2000, which improved cold starting and throttle response. While the core 497cc engine remained consistent, continuous refinements were made to the suspension. This included the integration of AWS V front and FasTrack rear suspension, followed by the addition of the Extra Travel Tunnel (ETT) rear suspension in 1999, Smart Ride Suspension in 2002, and Ryde FX shocks in 2003, enhancing comfort and handling. Q: How can I ensure this part fits my snowmobile?
