Скачать или смотреть The Ultimate Axle Upgrade: Why We’re Running 40-Spline RCV Shafts in Our Jeep Rock Bouncer Build

When you’re building a Jeep/Rock Bouncer hybrid, you can’t skimp on drivetrain strength—and that’s why we’re going all-in with RCV Performance 40-spline axles on Build For Off Road.

In this episode, we break down the science behind RCV constant velocity (CV) joints and why they’re the strongest, smoothest axles you can put under your rig. From massive 14-bolt and Dana 60 housings to big bell RCVs, this setup is built to take abuse on the rocks, in the mud, and everywhere in between.

Here’s what makes RCV axles the go-to for serious off-roaders:
✅ Constant Velocity Design – Six points of contact for smoother power delivery
✅ Stronger than U-joints – Reduces driveline shock and wheel hop
✅ Lifetime Warranty – Coverage up to 43” tires (and unlimited for 40-spline Big Bells)
✅ Built in the USA 🇺🇸
✅ Optional 300M Material for ultimate strength
