Warranty Comparison

Reliability Comparison

The Ford F?Super Duty’s engines use a cast iron block for durability, while the Sierra HD’s 6.0 V8 engine uses an aluminum block. Aluminum engine blocks are much more prone to warp and crack at high temperatures than cast iron.

The F?Super Duty 5.4 V8/6.8 V10 has a standard “limp home system” to keep drivers from being stranded if most or all of the engine’s coolant is lost. The engine will run on only half of its cylinders at a time, reduce its power and light a warning lamp on the dashboard so the driver can get to a service station for repairs. The Sierra HD doesn’t offer a lost coolant limp home mode, so a coolant leak could strand you or seriously damage the truck’s engine.

The F?Super Duty 4x4 has a solid front axle with a floating power axle for durability that the Sierra HD 4x4’s independent front suspension and exposed front driveshafts don’t offer.
