Longfield Jimny JB33 and JB34 Front Axle Kit The Longfield Jimny JB33 and JB34 33-Spline and 22-Spline Front Axle kit is a great alternative for those who want axles that are stronger than stock but don’t want the hassle of purchasing and installing 26-spline side gears in their front differential. The Longfield birfields are made out of 100.0 percent chromoly steel 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 4340 chromoly steel axle shafts are 22-spline on the differential side for easy installation into stock differentials. 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. This kit is 21.0 percent stronger than stock.
