This Tie Down Engineering integral hub and rotor combination features a Gal-V coating to protect the steel construction from corrosion. The vented disc design helps cool down the rotor at a quick rate every time braking is applied to prevent rotor warping and heat related damage. Product Features: Cast steel construction coated with a Galv-X finish for lasting durability and protection against fresh water and salt water environments Vented disc rotor dissipates heat from stopping quickly and efficiently to prevent damage to the rotor and components. Pre-pressed inner and outer race. Pre-pressed bolts. Disc brakes perform the most optimal braking for trailers and require less maintenance compared to drum brakes.
