CD009/A Straight-Cut Gearset

The ADOPT CD009/A reinforced, straight-cut motorsports gearset is engineered for the Nissan CD009/A 6MT transmission, suitable for all applications, including conversions. This gearset features high-strength straight-cut spur gears and reinforced input shafts, offering a significant upgrade over the OEM standard gearset. The Dogbox versions are anticipated for market release in July 2026, with the first orders shipping in October 2026. Multiple gear ratio sets are offered, including the S1 Synchro Sports set designed for road and dual-use cars, featuring taller 1st and 6th gears for improved drivability and economy, with more tightly grouped 2nd-4th gears. The R1 Dogbox offers enhanced durability for severe use, while the R1C Cross/close-ratio dogbox is a dedicated circuit specification with optimized gearing for track speeds. Custom bespoke gearing is also available upon request. Additionally, ADOPT offers various gear packs, such as a complete 1st-6th replacement (including a reinforced input shaft) with options for straight-cut or helical-cut 6th gears, a 1st-4th multipack for those who wish to retain OEM 5th and 6th gears, a budget-friendly 3rd-4th pack, and a 1st-2nd close-ratio pack. The product is manufactured in Australia and has an estimated lead time of 3.5 months, with a projected market ETA of July 2026.
