Trail-Gear 304097-3-KIT Features:

The Longfield Suzuki JB33/JB43 33-Spline Front Axle shafts are made out of 4340 chromoly steel. The Longfield birfields are made out of 100% chromoly and are precision polished to remove any imperfections that may cause stress risers. The internals of our Longfield birfields are made out of 4340 chromoly steel and then dual heat-treated for superior strength. The shafts are 22-splines on the differential side. The Birfield side of the axle shaft and the inner race of the Birfield have been upgraded to 33-splines to better distribute the torque loading.

Using 4340 chromoly steel, dual heat-treating the internals of our birfields, and upgrading the spline count to 33-splines, this kit is now 60% stronger than stock!
