31 Spline axles are fine. The 35 splined axles with an ARB require the axles to be shortened, due to the large ARB cross-shaft. The note is only for 35 splined axles.
Hello I have ID'd my housing as a 76-77 11X21/4. I will be running an ARB AIR locker and see the following note: NOTE: please choose 35 W/ARB if you plan to run an ARB air locker. Can I get 31 spline that will work with an ARB since I will not be upgrading the housing? <br><br>Thanks,<br>SP Ford 9-inch Rear Axles | 31/35-spline, Large Bearing, 11 inch | 76-77 Ford Bronco
