Yet another CALMINI exclusive. No longer do you have to worry about breaking rear axles while running large tires off-road! Our completely new forged axles are 30% stronger than the stock. Made from 4140 alloy steel, their redesigned input spline area greatly reduces the chance of them shearing or breaking. If you are running oversize tires and a locker, these axles are a necessity. Axles are the 4-bolt style and might require the early model brake backing plate for the later model 5-bolt style equipped vehicle.
