Rancho rockGEAR Differential Cover

The Rancho rockGEAR Differential Cover delivers trail-proven drivetrain protection for off-road enthusiasts who won't compromise on durability. Engineered as a direct bolt-on replacement for the factory stamped steel cover, each rockGEAR differential cover is built from high-strength nodular ductile iron — a material chosen for its exceptional ability to withstand rock strikes, impacts, and debris that can crack or deform a stock unit. The result is a rugged, purpose-built cover that safeguards your ring gear, pinion, and internal differential components on the harshest terrain.

Key Features:

• High-Strength Nodular Iron Construction — Superior impact resistance and long-term durability that far exceeds factory stamped steel, protecting internal gear components from direct trail contact
• Ribbed External Design — Structural ribbing reinforces the cover while also optimizing approach and departure angles, allowing the cover to glide over obstacles more smoothly than flat-profile stock units
• Offset Oversized Fill Plug — Engineered to ensure optimum housing fluid levels with easier, quicker access for routine fluid changes
• Increased Fluid Capacity — Greater differential fluid volume helps manage operating temperatures and extend the service life of internal drivetrain components
• Durable Powder-Coat Finish — Corrosion-resistant finish protects against rust for lasting appearance and performance in harsh off-road conditions
• Direct Bolt-On Installation — Replaces the factory cover using existing mounting points for a straightforward, no-modification install
• Limited Warranty Coverage — Backed by Rancho's structural warranty against defects
