Demon Powersport PAXL-8019XHD-4C X-Treme Heavy Duty ATV/UTV Axle Chromoly - 4340

The Demon Powersport X-Treme Heavy Duty Axle delivers race-proven performance for extreme off-road conditions. Engineered for desert racing, sand dunes, mud, rock crawling, and short course competition, this "Hell Rated" axle represents the strongest option in Demon's product line.

Complete 4340 Chromoly Steel Construction:

Unlike conventional axles that use chromoly only in the shaft, this X-Treme Heavy Duty axle features 4340 chromoly steel throughout every component—shaft, housing, cage, race, and balls. The material's elastic properties absorb stress within the axle itself, preventing stress transfer to your differential and drivetrain while preserving other vehicle components.

Enhanced Strength and Durability:

• 20-30% larger CV joints and shafts compared to standard heavy-duty axles
• Proprietary dual heat treatment process for superior strength
• Re-engineered cage design for enhanced durability
• Micro-polished internal components reduce heat buildup
• Molybdenum grease lubrication for extreme conditions
• Swing angles up to 47 degrees for maximum articulation
• Unique boot design for improved protection

Long Travel Kit Compatible:

Factory-optimized for long travel suspension and lift kits from major manufacturers including Cognito Motorsports, Extreme Performance, HCR, LSK, Lone Star Racing, and many others. The heat-optimized design keeps CVs running cooler for extended component life.

Race Proven Performance:

Trusted by professional racers competing in BITD, SCORE, SNORA, and Dakar events. Backed by a 2-year limited warranty—an industry-leading coverage that demonstrates Demon's confidence in their engineering and quality control standards.

This axle enables you to run more power and larger tires without fear of failure in demanding sand, rock, trail, or mud conditions.
