Upgrading to a 40-spline wheel bearing setup is a significant strength increase over stock axle configurations. The larger spline count allows for thicker, stronger axle shafts that can withstand higher torque loads and harsh off-road abuse. By pairing this with Timken bearings and precision machined components, Crane Axle ensures a more reliable, longer lasting wheel end assembly that’s built to thrive under race and rock bouncing conditions.
