Jetuplusllc Premium Reversible Ice Scratchers 2890644 are heavy-duty, reversible track scratchers designed to help maintain proper track and engine temperature across varied snow conditions on compatible Polaris RMK and related models.

These replacement ice scratchers (part number 2890644) fit a wide range of Polaris snowmobiles, including many RMK, Khaos, Pro RMK, SKS and Patriot model years listed by manufacturer fitment. Built with a single-coil design and reversible blades, they’re intended to extend service life and give riders a simple, durable way to manage ice buildup and track temperature during trail and off-trail riding. The set ships new in black and includes a 90-day limited warranty.

What makes the 2890644 scratchers different from standard ice scratchers?

The 2890644 units use a single-coil construction and reversible blades to prioritize durability and easy maintenance. That single-coil layout concentrates strength on the mount and coil area where trail forces are highest, while the reversible profile doubles usable life without complex installation.

• Single-coil design increases resistance to bending or breakage under stress;
• Reversible blades flip to use the second edge, reducing replacement frequency;
• Black finish resists corrosion and blends with common undercarriage components;
• Standard fitment for MY24 RMK models and wide cross-compatibility list.

Which Polaris models and years are these scratchers compatible with?

These scratchers are specified for many Polaris platforms across several model years. The listing includes SKS, RMK, Khaos, Pro RMK, Patriot and select Assault and Pro variants—refer to the detailed fitment list to confirm compatibility with your exact snowmobile configuration.

• Fits SKS 850/800 models (various track lengths and years 2016–2021 specific);
• Broad RMK compatibility including RMK SP, Khaos, Pro RMK and Patriot variants across 2016–2025 listings;
• Cross-references part placements 1545166 and 1545167 for verification;
• Intended as standard equipment on MY24 RMK models requiring part 2890644.

How do reversible scratchers benefit maintenance and trail performance?

Reversible scratchers let you flip worn edges, effectively halving blade-change intervals and saving time and parts. They also help control snow and ice interaction with the track, contributing to steadier track temperature and more consistent handling across changing snow types.

• Flip blades to restore scraping performance without immediate replacement;
• Helps shed packed snow and thin ice for better track-to-snow contact;
• Maintains more consistent engine and track temperature in varied conditions;
• Reduces downtime on the trail with a straightforward reversible design.

What should I expect during installation and service life?

Installation follows standard ice scratcher mounting procedures for Polaris undercarriage assemblies; no special tools are required beyond basic hand tools and proper torque specs. The single-coil architecture is optimized to withstand trail forces and the reversible feature extends usable life, but replacement intervals depend on riding style and terrain.

• Install using OEM mounting points for parts 1545166/1545167 where applicable;
• Routine inspections recommended after intense trail use or rock impacts;
• 90-day warranty covers manufacturing defects; wear from use is not covered;
• Reversible blades reduce frequency of full-part replacement.
