Upgrading to a 40-spline drive flange setup is one of the most effective ways to bulletproof a 14-bolt axle for off-road racing or hardcore trail use. The increased spline count offers a larger shaft diameter, distributing torque more evenly and reducing the likelihood of twisting or shearing under load. Crane Axle’s precisely machined drive plates and billet caps ensure a tight fit, proper sealing, and long term serviceability even under punishing conditions.
