Description

Upgrade your Dana 30 or Dana 44 front axle. This kit increases the distance between the inner and outer wheel bearings, reducing bearing load. Bearings ride on a forged 4140 chromoly spindle. Features an 8x6.5" wheel bolt pattern for increased strength and durability. Includes forged 4340 chromoly 35-spline stub shafts. Allows disengaging hubs for highway use or flat towing. Proprietary TeraFlex hub design seals OEM wheel speed sensors, maintaining ABS and ESP functions.
