Demon Powersport PAXL-8019XHD-3.75 X-Treme Heavy Duty ATV/UTV Axle Chromoly - 4340

The Demon Powersport X-Treme Heavy Duty Axle represents the pinnacle of performance axle engineering for ATV and UTV applications. Designed for extreme racing conditions including desert, sand, mud, rock crawling, and short course competition, this axle is built to handle the harshest terrains without failure.

4340 Chromoly Steel Construction Throughout:

Unlike conventional axles that use chromoly only in select areas, this X-Treme Heavy Duty axle features 4340 chromoly steel for every internal component—shaft, housing, cage, race, and balls. This premium alloy provides exceptional elasticity, allowing the axle to absorb stress internally rather than transferring it to your differential and drivetrain, helping preserve other vehicle components.

Key Performance Features:

• 20-30% larger CV joints and shaft diameter compared to standard heavy-duty axles
• Proprietary dual heat treatment process for maximum strength and durability
• Re-engineered cage design for enhanced longevity
• Micro-polished internal components to reduce heat buildup
• High-grade molybdenum grease for superior lubrication
• Larger swing angles up to 47 degrees for extreme articulation
• Unique boot design for improved protection
• Optional 300M shaft material available for select applications

Long Travel Compatibility:

This axle is engineered to work seamlessly with major long travel suspension and lift kits from manufacturers including Cognito Motorsports, HCR, LSK, Lone Star Racing, and many others. The optimized heat dissipation keeps CVs running cooler for extended longevity in demanding conditions.

Race-Proven Reliability:

Trusted by racers competing in BITD, SCORE, SNORA, and Dakar events, these axles deliver race-ready performance with extensive testing and quality control backing every unit. Backed by an industry-leading 2-year limited warranty, Demon Powersport stands behind the durability and performance of their strongest axle design to date.
