Why go with a roller bearing slip yoke?

Slip yokes found in many common applications run on a bushing inside the transmission tail housing. High-horsepower builds often use a roller bearing instead, so upgrading to a roller bearing yoke is a must — not only for proper fitment, but to guarantee the barrel is hard enough to avoid damage from the bearings. Plus, once you’ve reached that power level, you want a rugged yoke designed to handle it, not a bushing-style yoke that becomes a weak link in your driveline.
