Demon Powersport PAXL-3001XHD X-Treme Heavy Duty ATV/UTV CV Axle Shaft

The Demon Powersport PAXL-3001XHD is the brand's top-tier X-Treme Heavy Duty (XHD) CV axle, engineered for riders who demand maximum performance in the most punishing off-road conditions. Designed as a significant step up from the standard Heavy Duty line, this axle is built to withstand the rigors of desert racing, sand dunes, mud, rocks, and short-course competition.

Full 4340 Chromoly Steel Construction

Every component of the PAXL-3001XHD — including the shaft, housing, cage, race, and balls — is manufactured from 4340 chromoly steel and subjected to a proprietary dual heat treatment process. This material provides an excellent strength-to-weight ratio and greater elasticity, allowing the axle to absorb drivetrain stress rather than transferring it to the differential and surrounding components.

Key Features:

• Full 4340 chromoly steel construction throughout — shaft, cage, race, housing, and balls
• Proprietary dual heat treatment process for superior hardness and durability
• Re-engineered CV cage design for enhanced strength and range of motion
• 20–30% larger components compared to the standard Heavy Duty line
• Inboard joint allows up to 40° of articulation; outboard joint swings up to 45–47° depending on fitment
• Micro-polished internal components to reduce heat buildup during operation
• High-quality Molybdenum (Moly) grease lubrication on all internal components
• TPEE (thermoplastic polyester elastomer) boots for tear resistance and dynamic flex across temperature ranges
• Available in 300M shaft material for select fitments
• Compatible with major long travel and lift kit brands including Cognito Motorsports, HCR, Lone Star Racing, Long Travel Industries, and more
• CNC-machined for precise fitment and consistent quality

Long Travel Compatible

The PAXL-3001XHD is designed to work with all major long travel suspension and lift kits straight out of the box, with no additional modifications required. The wider swing angles and heat-optimized design make it an ideal solution for lifted and long-travel builds running larger tires or higher-output powerplants.

2-Year Limited Warranty

This axle is backed by Demon Powersport's 2-year limited warranty. Within the first year of purchase, Demon will ship a replacement axle at their discretion for covered failures. For failures occurring in year two, a replacement is available for a flat fee of $100. Note: the warranty covers the axle assembly and does not extend to CV boots and clamps.
