SPE Motorsport 10.25 and 10.5 Sterling Rear Differential Cover for Ford (1985-24) 6.7L Super Duty

•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 powder-coated 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.
