Early trucks all came with 6 lug axles. Not only does this limit your wheel choices, but it restricts your options on brakes as well. BROTHERS Trucks is here with the solution with our 5 lug axle conversion kits. These kits include axles, drums, differential cover gasket, and wheel studs. The axles are made from a high-strength alloy for strength and durability. This kit is designed for 1970 rear axles featuring 11-inch drums, 1/2-inch studs, a 5x5 lug pattern, and are 31-1/2-inch in length.
