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. Hurst Engineering is here with the solution of our 5 lug axle conversion kits. These kits include axles, limited slip differential, and drum brake assemblies. The axles are made from 1541H alloy for supreme strength and durability. This kit is designed for the 8.875 12-Bolt rear end with 3.42-lower ratio. Included are the axles featuring 30 spline ends, a 5x5" lug pattern, and are 30-3/4" in length. Look to Hurst Engineering for your truck axle needs.
