Nexus R3 / S3 / S2 Tube Mount Kit – 41.275mm (1.625″) Diameter: 41.275mm (1.625″)

Structural Integration: Nexus Tube Mount Kit (1.625″)

Securely mounting your VCU is as critical as wiring it. The Nexus R3 / S3 / S2 Tube Mount Kit is a precision-engineered billet mounting solution designed to integrate your Haltech Nexus unit directly onto the vehicle’s roll cage or tubular chassis structure. Specifically machined for 41.275mm (1.625-inch) tubing—a standard size for roll bar main hoops and cross-bracing in drag racing and circuit cars—this kit eliminates the need for zip ties, double-sided tape, or custom-fabricated sheet metal brackets. By providing a rigid, vibration-damped mounting point, it ensures that the internal accelerometers and gyroscopes within the Nexus unit operate with maximum accuracy, free from the resonance and flex of inferior mounting methods.

Engineering & Materials

The kit components are CNC-machined from high-strength 6061 Aluminum, chosen for its excellent strength-to-weight ratio and corrosion resistance. The brackets are finished in a durable black anodizing, providing a sleek, professional appearance that blends seamlessly with modern chassis coatings. The clamps are designed with a split-shell architecture, allowing them to be installed on existing cage bars without cutting or welding. The mounting plate is drilled specifically to match the footprint of the Nexus R3, S3, and S2 units, acting as a heat sink and a structural brace for the ECU body.

Operational Benefits

• Vibration Control: Rigidly secures the ECU to the chassis mass, reducing high-frequency vibration damage to internal components.
• Sensor Accuracy: Provides a stable reference plane for the ECU’s onboard 6-axis IMU (Inertial Measurement Unit), essential for traction control and datalogging.
• Professional Aesthetics: Replaces messy ad-hoc mounting with a factory-look billet solution.
• Ease of Service: Allows for quick removal of the ECU for bench programming or inspection.
