WPD-10R140-SS+ Super Stock Plus Transmission 800 HP

Super Stock Plus | 800 HP Rated The WPD-10R140-SS+ Super Stock Plus transmission is engineered for up to 800 horsepower, making it the ideal solution for trucks running larger turbochargers, aggressive tuning, and increased boost levels. Designed to sit perfectly between our Super Stock and Extreme builds, the SS+ delivers significantly more holding capacity and durability without sacrificing street manners or towing capability. This package focuses on upgraded friction materials, reinforced hydraulic components, and improved cooling to ensure consistent performance under high torque and sustained load—ideal for high-horsepower street trucks and hard-working tow rigs. Performance & Power Capability: 800 HP rated for high-output diesel applications Designed for larger drop in turbos and stock/small injectors Increased clutch holding capacity to manage elevated torque Firm, controlled shifts under load with smooth daily drivability Enhanced cooling for towing and high-boost operation Key Components & Upgrades: Raybestos GPZ Frictions with add capacity for superior torque capacity Raybestos Steel Module for increased durability match to the surface finish paired with the GPZ clutch stack. Seal Kit to maintain hydraulic integrity at elevated power levels with updated seals WPD Performance Valve Body for optimized shift control Updated CDF Drum to address known OEM failure points that fixes the “walked” bushing. Deep PPE Transmission Pan for increased fluid capacity and improved cooling with case rigidity as well as sediment separation from the filter pick up. New Main Pump for consistent line pressure at high horsepower Upgraded C-Clutch Hub for increased torque capacity OEM Internal Wiring Harness OEM Transmission Cooler to verify there is no left over contaminants in the cooler system. WPD 10R140-HD Torque Converter built to withstand increased power and boost with updated sprag oiling features and custom stalls available. This is not a billet front cover torque converter. Ideal Applications: High-horsepower builds with larger turbocharger Trucks pushing beyond super stock power levels Performance street trucks that still tow or work Customers wanting extreme-level strength without a full race build The WPD-10R140-SS+ Super Stock Plus offers the perfect balance of high-horsepower capability, durability, and real-world usability, making it the go-to transmission for serious builds that aren’t quite extreme—but demand more than super stock We do require a WP Developments approved TCM file to get full drivability and longevity out of the Super Stock 10R140.
