Polaris Ranger XP 1000 (2018-20) S4 Clutch Kit with AA Heavy Duty Primary & Secondary by Aftermarket Assassins

Description

Upgrade your Polaris Ranger XP 1000 with the Aftermarket Assassins S4 Clutch Kit, engineered for peak performance, reliability, and durability. This complete clutch system is designed to fit all 2018–2020 Ranger XP 1000 Standard models and 2019–2020 Ranger XP 1000 Crew models featuring the new body style. It does not fit the 61HP Single Cam models. Whether you’re trail riding, racing, dune climbing, or powering through mud, this clutch kit transforms your UTV into a stronger, faster, and smoother machine.

The S4 Clutch Kit includes a heavy-duty AA primary clutch built from high-grade tool steel with an encapsulated tower design, similar to the proven RZR Turbo models. It offers superior belt grip, reduced slippage, and long-lasting strength under extreme conditions. The kit also features the AA Revolver Billet Clutch Cover with Tower Lock for improved airflow and added durability. Magnetic adjustable clutch weights, HD primary and secondary springs, a precision-cut helix, and heavy-duty sliders and rollers are all included for a complete, ready-to-tune setup.

Experience faster acceleration, cooler belt temperatures, and buttery smooth engagement that eliminates factory clutch chatter at idle. The S4 kit delivers consistent power transfer and longer clutch life, making it ideal for vehicles with larger tires or performance modifications. Choose between the Performance Helix 1043 for aggressive, high-speed driving or the High Load Helix 1042 for heavy loads, larger tires, and crawling applications. Both options enhance acceleration and maintain RPMs where your engine produces peak power.

Designed for simple installation, the clutch is easy to adjust and fine-tune using the included magnetic weights and setup chart. Each component is crafted for durability, precision, and maximum efficiency, allowing you to get the most out of your Ranger XP 1000. The Aftermarket Assassins S4 Clutch Kit (Part 116-1012) is the ultimate upgrade for riders who demand professional-grade performance and reliability from their Polaris Ranger.
