Longfield gun drilled birfields are 100% chromoly, polished to remove stress risers, with dual heat-treated 4340 chromoly internals. A grease passage drilled through the birfield feeds an M8 zerk on the stub shaft, so the joint can be serviced without tearing down the axle. This kit fits the Y60 Nissan Patrol front axle.
