Pure Drivetrain Solutions GR Supra 8HP51 Transmission Hard Parts Kit - Stage 2

Overview

The Stage 2 Hard Parts Kit (HPK) from Pure Drivetrain Solutions is a premium performance strengthening kit engineered to dramatically enhance the durability and holding capacity of ZF 8-speed automatic transmissions (8HP series) used in high-power street and race applications.

Designed and manufactured in the USA, this kit upgrades critical internal components with high-strength, performance-focused hardware for enthusiasts and builders pushing their vehicles beyond stock limits.

Key Features & Benefits

This Stage 2 HPK builds upon the foundational upgrades of Stage 1 with additional components to increase strength, improve hydraulic performance, and boost overall transmission reliability under elevated power and torque loads:

• Billet 7075 E-Hub and C-Hub – Heat-treated and hard-anodized hubs designed to correct OEM weak points and enhance fluid flow, cooling, and structural integrity.

• Super-Alloy Clutch Pressure Plates (A/B/D) – High-strength plates engineered for improved torque capacity and longevity.

• Pure FSR Friction Plates (All Clutch Packs) – Proprietary friction material developed for consistent engagement and wear resistance under high load.

• Pure C6X Steel Plates – Industry-leading steels that enhance clutch pack durability and heat tolerance.

• Increased Friction Counts – Optimized across most clutch packs to handle higher holding demands.

Stage 2 Kit Contents

Stage 2 expands beyond core clutch hardware to include a full set of rebuild and reinforcement parts, making it ideal for performance builds, track use, or heavily tuned engines:

• Transmission Pan & Filter – New fluid path components to support clean, efficient operation.

• Comprehensive Gasket & Seal Kit – Full sealing hardware to ensure proper reassembly and leak-free operation.

• Custom PDS D-Piston – Upgraded piston design for improved hydraulic actuation and clutch application consistency.
