Labwork 14-Bolt 10.5" Rear Differential Cover for 1973-2000 Chevy GMC

Key Features

• Exceptional Strength & Structural Protection: Engineered with a reinforced design and heavy-duty structural composition to act as an armor shield, protecting your differential gears from rocks, debris, and harsh off-road impacts.

• Advanced Heat Dissipation: Designed to optimize thermal conductivity, keeping your gear oil cool and preventing oil degradation even during intense heavy towing, hauling, or high-load conditions.

• Enhanced Gear Lubrication: Features an optimized internal cavity that improves gear oil circulation, effectively reducing internal friction and heat buildup to prolong the service life of your differential system.

• Precision Vehicle Integration: Formulated with precise dimensions and professional engineering to guarantee a perfect seal and a seamless, leak-free bolt-on installation.

• Refined Styling: Adds a rugged, sophisticated aesthetic to your vehicle’s chassis while significantly decreasing the risk of expensive mechanical maintenance.

Crucial Fitment & Buyer Notice

Please Read Before Purchasing: To ensure proper installation and avoid return shipping fees, you must physically inspect your vehicle's rear axle before ordering.

• Axle Requirement: This cover fits ONLY models equipped with a FULL FLOATING AXLE. Some 2500 and 3500 series trucks are equipped with semi-floating axles, which are not compatible.

• Ring Gear Verification: Visually confirm that your rear end is a 14-Bolt differential with a 10.5" Ring Gear. This cover WILL NOT FIT the smaller 14-Bolt 9.5" variant or the larger 14-Bolt 11.5" variant.
