Longfield FJ80 Gun Drilled 30-Spline 4340 Chromoly Super Set

The Longfield™ FJ80 Gun Drilled 30-Spline 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 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 FJ80 Gun Drilled 30-Spline 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 stub shaft of the Birfield has dual snap ring grooves to accommodate FJ80s with short and long drive flanges.

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

Included in this kit is a set of new FJ80 ABS Tone Rings. This will allow you to install the Longfield™ FJ80 Gun Drilled 30-Spline Super Set on both ABS and Non-ABS FJ80 applications. No other kit on the market can compare.

Note: Included is the FJ80 Extended Dust Caps for 1990-1993 models that use short drive flanges.

A new, innovative, never before seen product, our Longfield™ Studless Hubs set the bar in quality and performance. The Longfield™ Studless Hub replaces the weaker, prone-to-breaking locking hubs, hub gears, and hub studs by utilizing a stud-less hub design and inner locking puck. Chances are, if you were to break the studs in your hub, the threads would be damaged and the hub would need to be replaced. With the Longfield™ Studless Hubs, you will never again need to worry about your hubs, hub gears, and hub studs breaking on the trail.

The Longfield™ Studless Hub and Inner Locking Puck are both constructed out of chromoly steel for superior strength and quality. The Longfield™ Studless Hubs are stronger than the OEM locking hubs and are designed to handle even higher torque loads than our Creeper Drive Flanges. The Longfield™ Studless Hubs will also include a full set of front wheel bearings to replace your old, worn out bearings.

We are so confident with the quality and strength of our new, innovative Longfield™ Studless Hubs.
