When going long travel on your four-wheel drive 1996-2004 Tacoma and 1996-2002 4-Runner you will need longer front axles to compensate for the increased trackwidth and allow for the increased wheel travel. We use these OEM Toyota complete axle assemblies that are not only the correct length for our kit but are also considerably stronger with their high angle CV’s. They are fully assembled and ready to be installed. These are not cheap remanufactured or lesser quality aftermarket versions you would get from an auto parts store. If your vehicle has manual locking front hubs, you will need to have custom axle shafts made as these are not compatible.
