The Chevrolet Silverado HD’s engines use a cast iron block for durability, while the Titan XD’s engine uses an aluminum block. Aluminum engine blocks are much more prone to warp and crack at high temperatures than cast iron.
In the Chevrolet Silverado HD, the optional 6.6 turbo V8 diesel has a gear driven camshaft to prevent engine damage from a broken camshaft belt or chain. Gears don’t exert side forces against the camshaft that can wear the cam bearings. The engine in the Nissan all use chain driven camshafts.
To reliably start during all conditions and help handle large electrical loads, the Silverado HD has a standard 720-amp battery (1460 diesel). The Titan XD’s 710-amp battery isn’t as powerful.
A reliable vehicle saves its owner time, money and trouble. Nobody wants to be stranded or have to be without a vehicle while it’s being repaired. Consumer Reports rates the Chevrolet Silverado HD 3500HD’s reliability 13 points higher than the Titan XD and the Chevrolet Silverado HD 2500HD is rated 22 points higher than the Titan XD.
