The Longfield™ Gun Drilled Birfields are made out of 100% chromoly and are precision polished to remove any imperfections that may cause stress risers. The internals of the birfield are also made from 4340 chromoly and are dual heat treated for superior strength. The bells are 30 Spline count, Inner and outer are 30 Spline, Making them not interchangeable with stock shafts that are 24 spline at the bell. The birfield has a M8 grease zerk at the end of the stub shaft and is gun drilled through the center of the birfield to allow for grease to pass through the zerk fitting and into the internals. This will save you precious time by eliminating the need to disassemble your axle just to service your birfields.

The Gun Drilled Birfields also have a shallow relief near the splines on the stub shaft known as a Machined Spline Saver. The Machined Spline Saver eliminates stress concentrations caused by grooving from the tool that makes the splines on the stub shaft. The stress concentration from the spline groove is a common failure point on birfield stub shafts.

The axle shafts are also made out of 4340 chromoly steel.

Kit Includes: Two ABS tone Rings and Extended Dust caps for 90-93 Models with short drive flanges, 1990-1993 Consider upgrading to the later model longer drive flanges.
