Designed and developed by our engineering and race team, this gear differential offers several great improvements over the ball differential design. - Consistent and easy setting with less frequent maintenance, with very little change from race to race. - Improved handling ability with more stable cornering entry, and improved mid and particularly exit rotation. - Fully ball raced for high precision, performance and lower maintenance. - Steel axle for strength and reliability. - 60T 48dp spur included. - The oil viscosity can be adjusted, to offer greater tunability than the ball differential. (700cSt-2000cSt) suited to low grip conditions. (2000cSt-5000cSt) suited to medium grip conditions. (5000cSt-15000cSt) suited to high grip conditions. - The (removed kit) ball differential may still be used when the track grip is low, but in other conditions this gear differential should always offer more potential. Ball Diff – Easiest to drive – best for low grip tracks. Gear Diff – Moderate to drive – best for all round conditions with tunability with the correct oil. - U8353 Optional carbon axle available for ultimate performance, 8g lighter.
