Description

Polaris General 1000 engines respond well to added displacement. This 98mm big bore top end kit increases cylinder size and compression to deliver stronger low-end torque and quicker throttle response. All parts are covered by a 1-year REV6 parts warranty.

By replacing the cylinder, pistons, and sealing surfaces together, this kit helps ensure proper clearances and reliable compression. It’s a solid upgrade for riders who want more pull without sacrificing durability.

THIS KIT INCLUDES
