Product Overview: Genuine Polaris Competition 155″ Track

Maximize your backcountry performance and conquer steep terrain with the authentic Polaris Competition 155″ x 2.1″ 2.86″ Pitch Snowmobile Track (OEM Part #2877304). Originally equipped on legendary crossover and mountain models like the 2010 800 Assault RMK, this competition-proven track is designed for riders who split their time between deep powder and hard-packed trails.

Its race-bred design has been rigorously tested in hill-climb competitions to deliver aggressive traction when charging up steep slopes or navigating mixed snow conditions. Available directly through PolarisPartCanada.com, this high-performance replacement track ships quickly right to your door anywhere in Canada.

Compatibility & Fitment

Precision-engineered by Polaris for specific crossover and mountain snowmobile architectures:

• Primary Vehicle Compatibility: Fits select legacy and modern Polaris deep-snow and crossover sleds requiring a 155-inch length, 2.86-inch drive pitch, and standard tunnel clearances (such as select RMK and Assault platforms).

• OEM Part Number: 2877304 (Cross-referenced with factory part #5413517)

• Drive Pitch: 2.86 inches

• Dimensions: 15″ width x 155″ length with 2.125″ lugs

Note on Fitment: Always verify your chaincase driver pitch, tunnel clearance, and suspension length before ordering to ensure seamless compatibility with your specific sled year and model.

How It Works & Functional Engineering

The Competition track features a stiff durometer rubber construction that resists lug roll-over under hard acceleration, ensuring maximum transfer of horsepower to the snow.

The precision 2.125-inch lug profile bites deeply into soft backcountry powder, while maintaining exceptional stability and grip when crossing hard-packed trails or wind-scoured ridges. Factory pre-porting helps clear out unwanted snow dynamically to minimize rotating mass and prevent packing.

Performance Benefits

Equipping your snowmobile with a genuine Polaris Competition track delivers immediate practical advantages:

• Hill-Climb Proven Traction: Engineered to excel in demanding backcountry ascents and aggressive cross-country maneuvers.

• Stiff Durometer Lugs: Resists flexing under high-horsepower applications for immediate hole-shot response.

• Pre-Ported Clean-Out: Strategically placed porting sheds loose snow efficiently to keep the track lightweight and responsive.

• Versatile Performance: The 2.125″ lug height bridges the gap between deep powder floatation and hard-pack trail bite.

Build Quality & Materials

Manufactured to stringent industrial standards under strict quality control guidelines:

• Rubber Compound: High-tensile, durable elastomer blend designed to withstand sub-zero temperatures without cracking or stiffening prematurely.

• Reinforcement: Multi-ply fabric casing providing high puncture and stretch resistance under heavy torque loads.

Installation & Setup Instructions

Replace your snowmobile track safely in your garage or shop:

1. Elevate Rear: Safely elevate the rear of the snowmobile off the ground using a sturdy stand so the skid frame hangs freely.

2. Remove Obstructions: Remove the rear bumper, snow flap, exhaust components, or suspension bolts necessary to slide the rear suspension skid out from the tunnel.

3. Drop Drive Axle / Loosen Track: Loosen the track tension bolts completely, remove the chaincase cover if necessary, and slip the old track off the drivers.

4. Install New Track: Feed the new Polaris Competition 155″ track into the tunnel, ensuring proper directional rotation arrows match forward movement.

5. Reassemble & Align: Reinstall the rear suspension, adjust track tension and alignment to factory specifications, and lock down all axle bolts.

Built specifically to endure punishing Canadian winters—including sub-zero deep freeze conditions, abrasive icy crusts, and heavy spring slush—this genuine OEM track resists rubber tearing and lug chunking season after season.
