AMS Performance DL800 Stage 4 Dodson 9/9

The AMS Performance Gearworks Stage 4 upgrade for the DL800 transmission elevates performance and durability with the addition of a Dodson billet second gear, making it the ideal entry-level choice for R8 and Huracan owners targeting high-powered setups around the 1200 WHP range. Building on the exceptional foundation of the OEM DL800 gear set, the Stage 4 package includes the robust Dodson Billet Second Gear, providing added strength to one of the transmission’s most stressed components. With the trusted Dodson Promax clutch kit, billet baskets, and a 9/9 clutch pack, the Stage 4 maintains maximum torque-handling capabilities while preserving the smooth, stock-like drivability and sound you expect. Proprietary AMS internal modifications reinforce critical oiling system components, adding reliability under the most demanding conditions. The Stage 4 upgrade is engineered for those pushing their supercars to the edge, offering improved strength without sacrificing everyday usability.

The Dodson Promax 9/9 Plate Clutch Kit

Stepping up from a standard “street” clutch solution, the Dodson Promax clutch assembly is a complete unit with a full billet housing, making it nearly bombproof. At the heart of this clutch system are upgraded 9/9 friction disks and steels, striking a perfect balance between torque holding, NVH, drivability, and cost. This comprehensive design also includes machined billet high-grade hardened baskets, and a high-grade billet steel lid and splines with a billet turned cover. If you’re looking for the best clutch upgrade available for the DL800 transmission in your high horsepower R8 or Huracan, look no further.

Dodson Second Gear Upgrade

One of the more common failures seen when making over 1000 HP is the OEM second gear stripping teeth due to the high level of torque the engine is putting out. Because it is not caused by a driveline shock, like many other driveline failures are caused by, this can happen even to R8s and Huracans that never see the drag strip. Dodson has provided a solution with a second gear-only upgrade unit that matches your existing gearbox’s ratios. This upgrade helps make the Gearworks Stage 4 transmission one of the most robust gearboxes available.

Titanium and Billet Aluminum Upgrades for Future Servicing

The AMS Gearworks Stage 4 DL800 Transmission is fortified with key components that prioritize preventative maintenance, ensuring long-term reliability and performance. The Dodson Billet Trans Pan enhances oil flow and reduces aeration while improving heat dissipation, helping to maintain optimal transmission temperatures and preventing overheating in high-stress conditions. The AMS Performance Titanium Bolt Kit mitigates the risk of oil leaks by replacing the stretch-prone OEM hardware with reusable aerospace-grade titanium and chromoly steel bolts, providing a secure seal that withstands repeated servicing. Additionally, the AMS Billet Filter Housing eliminates the vulnerability of the OEM plastic design, with its durable 6061 aluminum construction and leak-resistant Viton O-ring seal. This design also allows for transmission fluid filter changes, whereas the OEM pan and filter is entirely non-serviceable.  Together, these upgrades proactively address common wear points, minimizing the likelihood of costly repairs and keeping your transmission running smoothly.
