The XRAY 364913 Composite Center Gear Differential Adapter is tailored for the XB4 2020 platform, adding a larger internal cavity that helps the car stay composed through fast straights and aggressive turns. This upgrade targets smoother weight transfer and more predictable mid-corner behaviour.
Manufactured from a high-strength composite formulation, the adapter balances toughness with precision. The material resists fatigue and keeps the gear assembly aligned during repeated loading at race pace.
Engineered to match the XB4 2020 mounting points, this adapter installs without chassis modification and works as a direct replacement or performance upgrade. It is suitable for racers wanting improved handling and long-term durability.
