Rancho rockGEAR Differential Cover

1997–2018 Jeep Wrangler TJ, JK

RS6209

Overview:

The Rancho rockGEAR differential cover is engineered specifically for Jeep Wrangler TJ and JK models from 1997 through 2018. Designed to provide robust protection for your vehicle’s differential, this cover shields the axle and internal gears from damage caused by rocks, debris, and other trail obstacles encountered during off-road adventures. Ideal for off-road enthusiasts and Jeep owners who demand durability and reliability, the Rancho differential cover enhances the longevity of your drivetrain components while maintaining ease of maintenance.

Whether you’re tackling rugged trails, rock crawling, or trail riding, this differential cover offers peace of mind by reinforcing one of the most vulnerable parts of your axle assembly. Its rugged construction and thoughtful design make it a trusted upgrade for serious Jeep owners.

Key Features:

Built to withstand the harshest off-road conditions, the Rancho rockGEAR differential cover combines strength, functionality, and corrosion resistance. Key features include:

• Heavy-Duty Construction: Made from high-strength nodular iron (ductile iron steel) for superior impact resistance and durability.
• Ribbed External Design: Reinforced ribs provide extra structural strength to protect against rocks and trail hazards.
• Off-Set Oversized Fill Plug: Allows for increased fluid capacity and simplifies the process of filling and checking differential fluid levels.
• Corrosion Resistant Finish: Finished with a durable red powder coat that resists rust and corrosion, ensuring long-lasting protection.
• Direct Fitment: Designed to mount precisely on Dana 44 differentials found in Jeep Wrangler TJ and JK models.
• Limited Warranty: Backed by Rancho’s limited one-year warranty for added confidence in quality and performance.

Construction & Design:

The Rancho rockGEAR differential cover is crafted from nodular iron, also known as ductile iron steel, which offers excellent toughness and impact resistance compared to standard cast iron. This material choice ensures that the cover can absorb and deflect impacts from rocks and trail debris without cracking or deforming. The ribbed external design further enhances structural integrity, distributing stress evenly across the cover’s surface.

Its red powder-coated finish not only provides a visually appealing look but also serves as a protective barrier against rust and corrosion, which is essential for vehicles exposed to mud, water, and harsh environmental conditions. The offset oversized fill plug is strategically positioned to increase fluid capacity and facilitate easier maintenance, reducing downtime on the trail.

Installation & Fitment:

Installation of the Rancho rockGEAR differential cover is straightforward and requires no modifications to your Jeep’s axle assembly. It is designed to fit Dana 44 differentials on Jeep Wrangler TJ models from 1997 to 2017 and JK models from 2018. The cover replaces the factory differential cover using existing mounting points and hardware, making it a direct bolt-on upgrade.

For best results, it is recommended to drain the differential fluid before installation and refill with the appropriate gear oil after the cover is securely mounted. This ensures optimal lubrication and protection of your differential components.
