Demon Powersport PAXL-8019XHD-3C 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 "Hell Rated" axle delivers uncompromising strength and durability for the most demanding terrain.

Premium 4340 Chromoly Steel Construction:

Unlike conventional axles that use mixed materials, the X-Treme Heavy Duty Axle is constructed entirely from 4340 Chromoly Steel—including the shaft, housing, cage, race, and balls. This elite material choice provides superior elasticity, allowing the axle to absorb stress internally rather than transferring it to your differential and drivetrain, helping preserve other critical drivetrain components.

Race-Proven Performance Features:

• 20-30% larger CV joints and shaft components compared to heavy duty alternatives
• Proprietary dual heat treatment process for enhanced strength and longevity
• Re-engineered cage design for improved durability under extreme loads
• Micro-polished internal components to reduce heat buildup and friction
• High-performance Molybdenum grease for superior lubrication
• Unique boot design for better protection and sealing
• Larger swing angles up to 47 degrees for extended travel applications
• Available with 300M shaft material for select applications

Long Travel Suspension Compatible:

These axles are specifically engineered to work with major long travel suspension kits and lift kits from manufacturers including Cognito Motorsports, Extreme Performance, Fireball Racing HCR, NXS Designs, Madigan Motorsports, SF Raceworks, LSK, Lone Star Racing, Fifty6 Industries, FabWerx, Grounder 4, UTV Wolfpack, Reflex, and Long Travel Industries. The optimized heat management design keeps CVs running cooler for extended life even under aggressive racing conditions.

Trusted by Professional Racers:

Demon X-Treme Heavy Duty Axles are race-tested and proven in professional competition series including BITD, SCORE, SNORA, and Dakar, giving you confidence that these axles can handle whatever punishment you throw at them.

Industry-Leading Warranty:

Backed by an industry-first 2-year limited warranty, demonstrating Demon Powersport's confidence in their engineering and manufacturing quality.

Whether you're running high horsepower builds, oversized tires, or pushing the limits in extreme terrain, the Demon X-Treme Heavy Duty Axle provides the strength and reliability to keep you moving forward when lesser axles would fail.
