This 18x4x56 heavy-duty replacement rubber track featuring a Multi-Bar tread pattern is engineered as a direct OEM replacement, delivering the proper fit, durability, traction, and ride quality your Cat 277B was designed for.

The Caterpillar 277B is a powerful multi terrain loader (MTL) designed to deliver exceptional flotation and low ground pressure in soft, muddy, sandy, and finished surface applications.

Why We Recommend the PR Series™

For most Caterpillar 277B owners, we recommend the Grizzly PR Series™. Its premium anti-cut rubber compound, reinforced internal construction, X-Stream Roller Guard™ reinforced roller path, and heavy-duty track construction provide the best balance of durability, performance, warranty protection, and long-term value.

If your Caterpillar 277B is used daily for grading, landscaping, forestry, agriculture, material handling, snow removal, or other demanding applications, the PR Series™ is an investment that typically pays for itself through longer service life, reduced downtime, and lower overall operating costs.

The PM Series™ remains an excellent choice for equipment owners looking for dependable OEM-quality replacement tracks at a lower initial investment while still benefiting from Grizzly's proven construction and comprehensive 2-Year Warranty.

PR Series™ Premium Features

Anti-Cut Rubber Compound

The PR Series™ utilizes a premium all-season anti-cut rubber compound that combines natural rubber, synthetic rubber, carbon black, and performance additives to improve resistance to cuts, tearing, chunking, and premature wear.

Jointless Steel Cables

Continuous steel cables eliminate traditional splice weak points and improve long-term durability under demanding operating conditions.

X-Stream Roller Guard™ Reinforced Roller Path

The roller path is one of the most heavily stressed areas of any rubber track, constantly supporting the pressure and friction created by the machine's mid-rollers (bogies).

Grizzly's exclusive X-Stream Roller Guard™ reinforces this critical wear area to better resist cutting, deformation, and premature wear, helping extend track life and reduce downtime.

Forged Steel Inserts

Precision forged steel inserts improve strength and efficiently transfer power from the drive sprocket to the track while enhancing long-term durability.

Heavy-Duty Track Construction

The PR Series™ features a reinforced casement design that provides additional structural strength, stability, and durability throughout the entire track.

Metal Core Bars

Metal core bars provide additional structural support while helping maintain proper track stability throughout its service life.

PM Series™ Features

The Grizzly PM Series™ is an excellent option for equipment owners seeking dependable OEM-quality replacement tracks at a lower initial investment.

Features include:

• Wear Resistant Rubber Compound
• Jointless Steel Cables
• Reinforced Roller Path
• Metal Core Bars
• Forged Steel Inserts
• OEM Certified Construction
• 2-Year Warranty

Why Choose the Multi-Bar Tread Pattern?

The Multi-Bar tread pattern is engineered to provide exceptional versatility across a wide range of operating conditions. Its closely spaced tread bars provide outstanding traction while delivering a smoother ride than more aggressive lug patterns, reducing vibration and improving operator comfort throughout the workday.

The Multi-Bar design performs exceptionally well in soft ground, mud, dirt, gravel, and mixed terrain, making it one of the best tread choices for Multi Terrain Loaders like the Caterpillar 277B.

Benefits include:

• Excellent traction in mud, dirt, and mixed terrain
• Smooth ride with reduced vibration
• Excellent flotation on soft ground
• Outstanding performance on sensitive surfaces
• Long, even tread wear for extended service life
• Ideal for grading, landscaping, land clearing, agriculture, material handling, snow removal, and general construction

Why Brand Name Tracks Matter

Not all aftermarket rubber tracks are built to the same standards.

Many replacement tracks sold online are marketed simply as "Heavy Duty" without identifying the actual manufacturer. While they may fit your machine, internal construction, rubber compounds, manufacturing consistency, warranty support, and long-term availability can vary significantly.

Grizzly is an established rubber track brand built to proven specifications and backed by an extensive distribution network, consistent manufacturing standards, and a comprehensive 2-Year Warranty. When you purchase a Grizzly track, you know exactly what you're getting—and who is standing behind it.

Understanding Rubber Track Compounds

A common misconception is that "100% Virgin Rubber" automatically means a better rubber track.

In reality, premium rubber tracks are engineered using carefully balanced blends of natural rubber, synthetic rubber, carbon black, and specialized performance additives. These materials work together to provide the flexibility, abrasion resistance, strength, heat resistance, and durability required in demanding operating conditions.

The quality of the rubber compound design—not simply the percentage of one ingredient—is what determines overall performance and service life.
