The 37.5° spline pressure angle provides more surface contact between the spline teeth and the mating shaft, improving torque transfer and reducing spline wear under load. Combined with the forged 4140 steel construction, this yoke maintains superior structural integrity — preventing twisting and spline deformation even under the extreme shock loads common in off-road driveline setups. In short: better torque delivery, smoother operation, and longer component life.
