Spool Performance 8HP45, 8HP50, 8HP51 Stage 2 Upgraded Transmission
After over a year of rigorous testing, Spool Performance proudly presents our Stage 2 Transmission Kits for the 8HP45, 8HP50, and 8HP51 series transmissions. Engineered to surpass the limitations of stock components, these kits deliver an exceptional torque capacity of over 1000 ft-lbs. This comprehensive upgrade features advanced friction materials developed in-house, billet 7075 heat-treated and hard-anodized custom-designed C and E hubs, bespoke pressure plates, apply plates, and increased clutch counts for every clutch pack.
Advanced Hub Design
The C and E clutch hubs in the 8HP series are critical points of failure due to their OEM construction from weak, cast A380 aluminum. These components are prone to shearing or breaking of the lock splines, and the steel clutch plates can dig into the splines, causing hang-ups and burnouts.
Key Upgrades:
- Material: Re-engineered using 7075 series aluminum, one of the highest grades of billet aluminum.
- Treatment: Heat-treated and hard-anodized to enhance strength and surface hardness, providing superior resistance to shear forces and wear from steel disc engagement.
- Design Enhancements: Improved clutch cooling paths, oil evacuation, and increased clutch pack area for optimized performance.
Superior Friction Materials
Our FX-RT frictions, developed in-house, offer significantly higher friction coefficients than OEM materials. These frictions ensure performance and durability without compromising engagement and overall drivability.
Features
- Upgraded Friction Materials: In-house developed for higher friction coefficients and enhanced durability.
- Billet 7075 Hubs: Heat-treated and hard-anodized for superior strength and wear resistance.
- Custom Pressure and Apply Plates: Ensure optimal performance and ease of installation.
- Increased Clutch Counts: Enhanced torque handling capacity for every clutch pack.
Spool Performance Billet Aluminum 8HP Transmission Oil Pan
The Spool Performance Billet Aluminum 8HP Transmission Oil Pan is a high-quality upgrade engineered for drivers who demand the best from their vehicles. Designed specifically for ZF 8HP automatic transmissions, this oil pan is crafted from billet aluminum, offering superior durability and thermal efficiency compared to traditional plastic or stamped steel alternatives. The precision-machined construction ensures a perfect fit and integrates seamlessly with your transmission for improved performance and reliability.
Key Benefits:
- Enhanced Oil Capacity: The Spool Performance transmission oil pan increases oil capacity, allowing for better lubrication and more stable transmission temperatures. This added volume helps extend the life of transmission components by reducing the risk of overheating under demanding conditions.
- Improved Heat Dissipation: Billet aluminum is highly effective at dissipating heat, which helps maintain optimal transmission temperatures during high-performance driving. This results in more consistent transmission behavior and reduces the likelihood of overheating, even under heavy loads.
- Increased Durability: Unlike plastic or stamped steel oil pans, the billet aluminum construction of this oil pan offers superior strength and resistance to impacts from road debris. It is also more resistant to warping and cracking over time, ensuring long-lasting reliability.
- Direct Fitment: Engineered for a perfect fit with ZF 8HP transmissions, the Spool Performance Billet Aluminum Transmission Oil Pan allows for straightforward installation without modifications, making it an ideal upgrade for enthusiasts and daily drivers alike.
