This Yukon GM 14-Bolt nodular iron rear differential cover is for housings using metric 8mm cover bolts found in heavy-duty Chevrolet and GMC trucks, SUVs, tow rigs, and off-road builds.Constructed from thick-wall nodular iron, this cover improves housing rigidity during towing, hauling, high-torque applications, and aggressive off-road use.
Internal oil-flow shaping helps improve lubrication circulation and cooling, while the black powder coat finish and stainless hardware provide long-term durability and corrosion resistance. Designed for heavy-duty use where factory stamped covers are vulnerable to impact damage and deflection.

Tech Insight
The GM 10.5" 14 Bolt rear axle is one of the most durable factory truck axles ever produced and is commonly used in towing, work trucks, diesel applications, rock crawlers, and heavy off-road builds. As tire size, torque output, and vehicle weight increase, differential housing rigidity becomes more important for maintaining stable ring and pinion alignment.
A heavy nodular iron differential cover helps reinforce the housing while protecting the ring and pinion assembly from impacts that can crack or deform thin factory covers. This added rigidity can also help reduce housing flex during heavy towing and aggressive off-road driving.
