The TeraFlex Dana 60 / Tera CRD60 HD Differential Cover Kit is a heavy-duty axle protection upgrade built for extreme off-road use where maximum strength and durability are critical. Constructed from over 3/8" thick high-strength ductile iron, this cover is designed to withstand serious trail abuse from rocks, debris, and obstacles while reinforcing the axle housing itself. It helps maintain proper gear alignment under heavy loads, making it a key upgrade for high-torque, large tire, and hardcore off-road builds. Designed as a direct bolt-on replacement, this cover provides a simple yet highly effective way to protect one of the most expensive components in your drivetrain. ✔ Heavy-duty differential protection for Dana 60 axles✔ Over 3/8" thick ductile iron construction for extreme strength✔ Reinforces axle housing under heavy load✔ Protects gears from rocks, debris, and trail impacts✔ Direct bolt-on upgrade with included hardware
