The welded ProRock 44 end forging and tube is shown next to a stock JK 44 axle. Again, the size and strength of the ProRock components is ever apparent. For those after even greater strength, the ProRock 44 is also available with Danaa 60 end forgings. The Dana 60 forgings permit use of larger axle shafts, U-joints, ball joints, and a true locking manual hub. Configurations such as this are made to order and sold as a custom assembly. For most JK and TJ owners the 44 end forgings will offer adequate strength.
