TeraFlex Adventure series axles can be built in virtually any configuration. Stock Jeep knuckles can be used to retain Stock style unibearing assemblies, or can be built using the larger and more desirable Dana 60 knuckles and axle shafts (recommended). This creates a hybrid axle that has a smaller center section for minimum space and maximum ground clearance with the outer strength Dana 60 axles. The Adventure 44 offers Jeep vehicles an upgrade from Dana 30, 35, and 44 stock axles. The Trail 44 can be made to order with 30, 33, or 35 spline shafts, Call for more details.
