Early GM 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 conversion axles. These axles are made from 1541H alloy for supreme strength and durability. Our axles made for the 8.875 12-Bolt rear end feature 30 spline ends, a 5x5" lug pattern, and are 30-3/4" in length. Look to Hurst Engineering for your truck axle needs.Sold individually.
