Meet the X-Treme Heavy Duty Axles

If you're looking for axles that can handle the rough stuff, you've found them. Our X-Treme Heavy Duty Axles are built for the real deal—whether you're tearing through the desert, splashing through mud, or climbing rocky trails, these axles are ready to take on whatever you throw at them.

We’ve spent years fine-tuning these bad boys, and let me tell you, they're our strongest axles yet. Forget about those flimsy stock parts; these are designed for serious performance without draining your wallet. Our quality control is no joke, and we put each axle through rigorous testing before it ever hits the market.

Built Tough with 4340 Chromoly Steel

What makes these axles stand out? They’re made entirely of 4340 Chromoly steel, which is not only tougher but also more elastic than standard materials. This means they flex under pressure, absorbing stress and keeping it away from your drivetrain. You won't have to worry about breaking parts or losing power when you're pushing your ride to the limit.

We’ve beefed up the CV joints and shafts, and we’ve even re-engineered the cage design for added durability. Plus, we use a special dual heat treatment process that makes these components even stronger. They’re packed with Molybdenum grease, which keeps everything running smoothly and cool—no more overheating CVs!

Perfect for Long Travel Kits

These axles are not just strong; they’re also made to fit with all the major Long Travel Suspension Kits and Lift Kits. If you’re hitting the dunes or racing through the desert, these axles are optimized for heat management, so your CVs can keep their cool and last longer. Just ask any of our racers in BITD, SCORE, or DAKHAR—they trust these axles to get them through the toughest conditions.

Whether you’re running Cognito Motorsports, Extreme Performance, Fireball Racing, or any of the other top brands, our axles are designed to fit right in.
