Product Information
Overview
Introducing the HRD Honda B/K series Mainshaft Thrust Measurement Tool, an essential companion for transmission rebuilding. This tool allows you to accurately measure the main shaft thrust on your Honda's B or K series transmission, which is mandatory when swapping gearsets, especially on high-power builds with aftermarket gear sets. This is a must-have for any DIY transmission builder or professional mechanic.
Notably, our mainshaft thrust measurement tool is fully compatible with B series and K series transmissions, ensuring broad compatibility across a wide range of transmission models for any Honda enthusiast.
The increased stiffness of 7075-T6 ensures minimal deformation during measurement, providing more accurate and repeatable results with each transmission rebuild you undergo. Our material selection allows this tool to maintain its shape and dimensions better than 6061 under load. For a precision tool, dimensional stability ensures consistent readings and minimizes the need for recalibration over time.This is particularly important for a thrust measurement tool that may experience repeated contact with hard surfaces or components under significant pressure.
Please note that the dial indicator shown in the pictures is not included with our HRD Honda B/K Series Mainshaft Thrust Measurement Tool.

Technical Specs
This component is precision machined from 7075-T6 aluminum, which has a significantly higher tensile strength (about 74,000 psi) compared to 6061-T6 aluminum (about 42,000 psi). This superior strength makes 7075 better suited for tools subjected to high loads or stresses, such as those measuring mainshaft thrust, where precision under pressure is critical. The clamps are bead blasted and finished in Midnight Navy with Type II anodizing, providing both an attractive finish and added protection against wear and tear. Titan Frost Ti hardware is also included with the tool.

Dual Duty Design
The modern enthusiast asks their car to live two very different lives. It has to start every morning, survive traffic, and stay quiet enough to hold a conversation. Then, on demand, it has to feel sharp, confident and absolutely ready to hunt lap times or podiums.
At Happy Racer Development, that tension is not a problem to hide, it's the foundation of our Dual Duty philosophy. From dampers to drivetrain mounts to shifting hardware, every HRD component is engineered to operate across a wide spectrum of use, delivering real performance without sacraficing the ability to actually live with the car.
Refinement without loss of drivability is where Dual Duty truly differentiates itself. Anyone can make a part that feels extreme for a few laps; our goal is controlled, repeatable performance that you can live with every day.
