PPE 01+ GM Duramax Allison 1000 Stage 4 Transmission Kit 850HP

PPE 01+ GM Duramax Allison 1000 Stage 4 Transmission Kit 850HP




Clutches fail in high performance applications due to excessive heat. Don’t get burned! For the hard core performance addicts we have developed our Stage IV transmission kit. Transmission kits include clutches that withstand higher temperatures and stress than any other clutch available. Increased clutch surface area provides for increased holding, heat absorption, shorter lock-up time and decreased “slippage.” All clutch frictions and steel plates are made from high heat, wear and fatigue resistant material to ensure your Allison 1000 transmission can handle over 850 horsepower and 1,500 ft.-lbs. of torque without damage. This kit is designed to handle a Duramax with stacked performance chips and the use of propane and/or small nitrous kits. Included in this kit are a Triple Clutch Converter, valve body recalibration kit, and a replacement of clutches and steels with High-Friction C1, C2, C3, and C4 clutches with Kolene steels.

Application: LB7/LLY/LBZ/LMM Allison™ Transmission 1000 Series
