TorqueBar – Long-Grip Shifter Handle for Thrustmaster TH8S

TorqueBar transforms the compact TH8S shifter into a tall rally- and sequential-inspired control.

The extended central grip provides a large gripping area and allows the driver to choose a comfortable hand position. Its textured surface improves purchase, while the raised upper and lower guards help prevent the hand from slipping during quick shifts. The layered collars give it a distinctive machined, motorsport-inspired appearance.

Features

• Textured gripping surface

• Upper and lower hand stops

• Designed around the official Thrustmaster TH8S interface

Compatibility

This handle is designed for the Thrustmaster TH8S and uses the official TH8S adapter system.

Do not scale the mounting interface. Scaling it will alter the fit.

Recommended print settings

These are suggested starting settings and may require adjustment for your printer:

• Material: PLA+, PETG or another rigid filament

• Nozzle: 0.4 mm

• Layer height: 0.20 mm

• Perimeters: 5

• Infill: 20–30%

• Top and bottom layers: 5

For maximum strength, avoid placing a weak layer boundary across the mounting interface.

Assembly

1. Print the TorqueBar handle at 100% scale.

2. Print or obtain the official TH8S adapter.

3. Install the adapter by following Thrustmaster’s official instructions.

4. Fit the handle onto the adapter.

5. Confirm that it is fully seated and cannot rotate or wobble before use.

6. Tighten only as much as necessary; overtightening a printed part may damage it.

Because printers and materials have different tolerances, test the interface before applying significant force.
