Part #: 1C7 008 AS

Overview

The Cusco Billet Aluminum High Capacity Differential Cover is a premium upgrade designed specifically for the Toyota GR Yaris AWD (2020 and newer) and GR Corolla (2023 and newer, GZEA14H). Engineered with performance enthusiasts in mind, this differential cover enhances the durability and cooling capacity of your vehicle's differential system. Whether you're participating in spirited driving, track days, or off-road adventures, this high-capacity cover helps ensure your differential remains in optimal condition under demanding conditions.

Constructed from high-quality billet aluminum, the Cusco differential cover not only provides increased oil capacity but also offers superior heat dissipation. By maintaining proper lubrication and reducing oil temperature, it effectively protects the limited-slip differential (LSD) and gears from heat-related wear and potential failure. This upgrade is ideal for drivers who push their vehicles hard and seek reliable performance and longevity from their drivetrain components.

Key Features

The Cusco High Capacity Differential Cover is designed with precision and durability in mind, incorporating several key features that benefit performance and reliability:

• Constructed from lightweight, high-strength billet aluminum for excellent durability and heat conduction.
• Increased oil capacity compared to the stock cover, which helps to suppress oil temperature rise during aggressive driving or competition use.
• Enhanced cooling efficiency with a finned design that promotes better heat dissipation, keeping differential oil at optimal temperatures.
• Corrosion-resistant silver anodized finish that provides long-lasting protection against the elements and enhances the vehicle's aesthetic appeal.
• Precision-machined mounting surfaces for a perfect fit and easy installation using factory mounting points.
• Designed specifically for the Toyota GR Yaris AWD and GR Corolla, ensuring compatibility and optimal performance.
• Protects vital differential components by maintaining consistent lubrication and reducing thermal stress.
• Supports spirited driving, track use, and off-road conditions by improving differential cooling and oil capacity.

Construction & Design

The Cusco differential cover is crafted from high-grade billet aluminum, offering a significant upgrade over the factory stamped steel or plastic covers. Its robust construction ensures resistance to impacts and corrosion, making it suitable for both street and track use. The finned design not only adds a sporty aesthetic but also enhances heat dissipation, which is critical during high-performance driving sessions. The precision-machined mounting surfaces guarantee a secure fit, preventing leaks and ensuring reliable operation under demanding conditions. The anodized silver finish provides additional corrosion resistance and a sleek appearance that complements the vehicle's sporty character.

Performance & Benefits

By increasing the differential's oil capacity, this cover helps to keep the LSD and gears properly lubricated during intense driving, reducing the risk of overheating and wear. The improved heat dissipation capabilities contribute to more consistent differential temperatures, which is vital for maintaining optimal traction and handling. Enthusiasts will appreciate the peace of mind knowing their drivetrain components are protected during spirited driving or competitive events. The lightweight aluminum construction also helps reduce unsprung weight, contributing to improved handling and responsiveness.
