The Cometic C3528-EST Top End Gasket Kit is designed for Polaris 570 engines and includes components engineered to support reliable sealing and increased low-end performance. With a 99mm bore application, this kit raises compression to help improve throttle response and low-end power while maintaining the durability needed for recreational, utility, and off-road use.
Cometic manufactures these gaskets using materials selected for dependable sealing and torque retention. Graphite gaskets feature a steel core laminated on both sides with flexible graphite, providing strength and compliance across changing engine temperatures. Fiber gaskets are designed for maximum sealing performance, flexibility, and torque retention, while the included O-ring gaskets meet or exceed original equipment manufacturer specifications.
This Cometic top end gasket kit fits 2014–2017 Polaris Ranger 570 models, including Fullsize versions where specified, as well as 2014–2016 Polaris Sportsman 570 models.
