Through years of research and development Demon Powersports has developed a Race Ready Ultimate Performance axle that doesn't burn a hole in your pocket and adheres to the highest quality standards. These axles are bigger, beefier, and stronger. Demon X-treme Heavy Duty Axles are built using larger CV joints and shafts, paired with our proprietary dual heat treatment process, and 4340 Chromoly Steel material for all its components such as shaft, housing, cage, race, balls. This gives the axles the edge it needs for superior strength and longevity. We re-engineered our cage design to enhance durability and use Molybdenum grease to lubricate the internal components. The axle's inner components are micro-polished so the CVs don't heat up like the competitor's products. The axles are Hell Rated The Xtreme axles are tailor made for specific long travel kit manufacturers (+3,+3.5, +4, +4.5) and tailor made for specific lift kit manufacturers (+5, +6, +8).
