Dana 35 M200 Rear Differential Cover

OEM stamped covers are thin and vulnerable to rock strikes, leaks, and warping. The Spelab heavy-duty differential cover is engineered for Jeep owners who push their rigs in off-road, rocky, or muddy conditions. With reinforced strength, easy service ports, and superior sealing, this cover protects your gears and keeps you moving confidently on any trail.

Key Features

• Heavy-Duty Nodular Iron Construction – Stronger and more impact-resistant than OEM stamped steel covers.
• Reinforced Rib Design – Increases housing rigidity and reduces flex during off-road stress.
• High/Low Service Ports + Top Fill Port – Makes fluid checking, venting, and refilling easy even when lifted or angled.
• Magnetic Stainless Plugs with High-Temp Seals – Capture metal shavings while ensuring a long-lasting, leak-free seal.
• Recessed & Protected Bolts – Reduce the risk of bolt damage from rocks or debris on the trail.
• OEM Fluid Capacity & Proper Clearance – Maintains factory fluid volume without reducing ground clearance.
• Direct Bolt-On Replacement – Installs easily with no cutting, welding, or modifications required.
