Demon Powersport PAXL-6114XHD-2R Xtreme Heavy Duty Race Spec Axle 300M Steel

The Demon Powersport Xtreme Heavy Duty Race Spec Axle represents the pinnacle of UTV axle engineering, designed to eliminate CV breakages and drivetrain failures in the most demanding off-road conditions. Engineered with an aircraft-grade 300M steel shaft, this axle is built to flex and absorb extreme forces while maintaining superior durability under heavy loads, oversized tires, and aggressive riding.

Advanced 300M Steel Construction:

The 300M steel shaft sets this axle apart from conventional designs. This aircraft-grade alloy is a modified, reinforced version of 4340 chromoly steel, enhanced with vanadium and increased silicon content. Vanadium—commonly found in high-speed tool steel—elevates the material's strength to exceptional levels, while the higher silicon content enhances hardness and provides superior resistance to high-temperature oxidation. The result is an axle that performs flawlessly even in the harshest environments.

Key Features:

• 300M aircraft-grade steel shaft for maximum strength and flexibility
• Engineered to flex and absorb force, reducing stress on drivetrain components
• Larger CV joints and shafts compared to standard axles
• Proprietary dual heat treatment process for enhanced longevity
• Double plunge design allowing 1.5 inches of travel on inboard joint
• High articulation angles: 40° on inboard joint, 45-47° on outboard joint
• TPEE thermoplastic polyester elastomer boots—stronger and more puncture-resistant than OEM rubber boots
• Superior fatigue resistance and temperature tolerance
• Precision CNC-machined components
• Race-ready performance at an accessible price point

Applications:

Ideal for high-horsepower UTV builds, long-travel suspension setups, oversized tire applications, and competitive racing. This axle delivers the strength and reliability needed for desert racing, rock crawling, and extreme trail riding.

Demon Powersport has developed a race-proven solution that adheres to the highest quality standards without compromising affordability. Experience unmatched performance and say goodbye to constant axle repairs.
