Sterling 10.5"/10.25" Rear Differential Cover

The SPELAB differential cover is a rear differential cover specifically engineered for Ford Sterling 10.5"/10.25" 12-bolt differentials. Crafted from durable aluminum alloy and finished with a black wrinkle paint for rust resistance, this cover is built to enhance both performance and longevity. This differential cover incorporates an external heat sink design to maximize heat dissipation by increasing contact with surrounding air, coupled with internal diversion grooves to optimize lubrication flow. This superior cooling capability, compared to traditional iron materials, ensures consistent performance, especially under demanding conditions like heavy towing or off-road use. A key feature is the external observation mirror with a built-in floating ball, allowing for easy and reliable oil level monitoring, even if the mirror surface becomes clouded over time. The SPELAB differential cover is designed to fit 2011-2024 Ford F250, F350, and F450 models equipped with the 6.7L Powerstroke engine. It is compatible with the Ford Sterling 10.5"/10.25" 12-bolt differential. The product is backed by a 12-month warranty and a 30-day return policy.
