SPE Motorsport Ford Super Duty  10.25 And 10.5 Sterling Differential Cover

The SPE Motorsport Differential Cover for Ford Super Dutys is designed to do the job right — simple, durable, and built with real-world performance in mind.

• Simple Maintenance: Features NPT drain and fill plugs for easy service. If you ever need to replace a plug, standard NPT fittings make it simple.

• Proper Drainage: Drain plug is positioned at an optimized angle to drain nearly all fluid cleanly into a pan without running along the axle.

• Easy Filling: Large fill port allows direct bottle insertion for faster, easier fluid fills.

• Sealed Tight: Machined O-ring main seal — no RTV mess or guesswork.

• Stainless Hardware: Corrosion-resistant stainless steel bolts included.

• Designed for Performance: Internally contoured to maintain proper fluid flow across bearings, unlike cheap square covers that cause bearing starvation.

• Built for Clearance: Clears most factory and aftermarket sway bars.

• Finish Options: Available raw or powdercoated in a durable wrinkle black finish.

• Added Capacity: Increased fluid capacity for better cooling and extended differential life.

• Strength Where It Matters: Thick cover design improves axle rigidity under load.

• Built-in Cooling: Integrated heat fins help dissipate heat but are thick enough to handle real abuse — no fragile fins here.

Designed, tested, and built to outperform the rest — whether you're towing heavy, off-roading, or just want peace of mind.
