Pure Drivetrain Performance Built for High-Power Transmissions
1st Sep 2026
Adding horsepower is only part of building a serious performance vehicle.
As engine output and torque increase, the transmission and drivetrain have to handle significantly greater loads. A factory transmission may perform well at stock power levels, but high-horsepower builds can place substantially more stress on torque converters, clutches, internal components, and fluid systems.
Pure Drivetrain Solutions develops performance transmission components designed to address those demands, with a strong focus on high-performance automatic transmissions and torque converters.
At XPH, Pure Drivetrain products are available for enthusiasts building stronger, more responsive drivetrains around platforms including the widely used ZF 8HP transmission family.

Built Around the ZF 8HP Platform
The ZF 8HP has become one of the most widely used automatic transmissions in modern performance vehicles.
Its combination of fast shifting, efficiency, and broad application range makes it a popular foundation for modified vehicles. Once engine power is increased substantially, however, the transmission must be capable of reliably transferring that additional torque.
Pure Drivetrain offers components covering multiple 8HP variants, including applications for transmissions such as the:
- ZF 8HP45
- ZF 8HP50
- ZF 8HP51
- ZF 8HP55
- ZF 8HP70
- ZF 8HP75
- ZF 8HP76
- ZF 8HP80
The specific components and configurations vary by transmission and drivetrain layout, making proper transmission identification essential when selecting parts.
Billet Race Torque Converters
One of the key products in the Pure Drivetrain lineup is its range of billet race torque converters.
These converters are designed for high-output applications where the factory torque converter may become a limiting factor.
Pure Drivetrain offers different stator configurations depending on the transmission and intended application. Configurations such as 20/65, 22/60, and 26/50 are designed around different combinations of stall characteristics and torque multiplication.
The goal is straightforward: improve how the engine's power is converted into usable acceleration while maintaining reliable operation under increased torque loads.
Improving Launch and Power Transfer
For turbocharged performance vehicles, torque converter characteristics can have a significant effect on launch behavior and turbo spool.
A properly matched high-performance converter can help the engine reach a more effective operating range before and during launch, while reducing unwanted slippage once power is being transferred through the drivetrain.
This makes Pure Drivetrain converters particularly relevant for:
- drag racing
- roll racing
- high-horsepower street cars
- AWD performance builds
- track applications
- heavily modified turbocharged vehicles
The correct converter configuration depends on the transmission, drivetrain layout, engine characteristics, turbo system, and intended use.
Billet Construction for Increased Durability
High-power applications place considerably greater stress on drivetrain components than factory configurations.
Pure Drivetrain torque converters use precision-machined billet components and reinforced internal assemblies designed to withstand increased torque and heat.
Depending on the specific application, features can include upgraded internal components, reinforced stators and covers, improved lock-up clutch capacity, and precision balancing.
These upgrades are designed to provide more consistent power transfer under demanding conditions while improving durability compared with standard components.
Transmission Components Beyond the Torque Converter
Pure Drivetrain's product range extends beyond torque converters.
The company also develops transmission components designed to improve the reliability and performance of complete transmission systems.
For example, Pure Drivetrain offers transmission pans for ZF 8HP applications. Its 8HP50 RWD transmission pan is designed to provide durable construction and improved fluid management for both performance and maintenance applications.
This type of supporting hardware becomes increasingly important when building a drivetrain intended to operate under higher temperatures, increased torque, and repeated hard use.
Designed for Serious Performance Builds
Pure Drivetrain products are aimed at vehicles where drivetrain performance is an important part of the overall build.
Whether the goal is faster launches, improved power transfer, or greater transmission durability, upgrading the components responsible for transferring engine torque can help create a more complete performance package.
The brand's catalog covers a wide range of ZF 8HP configurations and drivetrain layouts, including both RWD and AWD applications.
That makes Pure Drivetrain particularly relevant for modern BMW performance builds and other high-output vehicles using ZF automatic transmissions.
Where Pure Drivetrain Fits in a Build
Pure Drivetrain is a natural choice for builds focused on:
- high horsepower and torque
- improved launch performance
- stronger automatic transmissions
- ZF 8HP upgrades
- drag and roll racing
- high-performance street driving
- AWD performance applications
- drivetrain reliability under increased power
The engine may make the power, but the drivetrain is responsible for putting it to the ground.
