31-Spline Differential Upgrade
The Tenaci Chromoly axle shaft features 31 splines on the differential side, providing increased torque capacity compared to smaller factory spline configurations.
The larger spline design offers improved load distribution and increased strength, making it ideal for high-performance Volvo applications.
Important: A compatible 31-spline differential or matching 31-spline side gears are required. These axle shafts are not a direct replacement for standard 27-spline differential configurations.
Not recommended for welded differentials due to the extreme shock loads and increased risk of axle shaft failure.
