Nexus R3 / S3 / S2 Tube Mount Kit – 31.75mm (1.25″) Diameter: 31.75mm (1.25″)

Structural Integration: Nexus Tube Mount Kit (1.25″)

The Nexus R3 / S3 / S2 Tube Mount Kit (1.25″) brings the same aerospace-grade mounting precision to smaller diameter tubing applications. Designed for 31.75mm (1.25-inch) tubes, this kit is ideal for mounting your Haltech Nexus unit to intrusion bars, dash bars, or exoskeleton frames often found in off-road buggies, ATVs, and lightweight tube-chassis vehicles. By utilizing a solid billet aluminum construction, this mount ensures that your engine management system remains securely anchored even under the severe shock loads of rally, drift, or off-road racing.

Engineering & Materials

Precision CNC-machined from 6061 Aluminum and finished with a hard-wearing black anodized coating, this kit is built to survive in exposed cabin environments. The 1.25″ clamps are engineered with a tight tolerance to prevent rotation or sliding once torqued, ensuring the ECU remains in its optimal orientation. This is particularly important for the Nexus series, which utilizes internal accelerometers; a loose mount leads to noisy G-force data and compromised traction control strategies. The mounting plate acts as a sturdy backbone for the ECU, protecting it from torsional stress.

Operational Benefits

• Rigid Stability: Ensures the ECU’s internal IMU receives clean data by coupling the unit solidly to the chassis.
• Versatile Mounting: 1.25″ size is common for dash support bars and side intrusion bars.
• Durability: Anodized aluminum resists corrosion and wear in open-cockpit environments.
• Complete Solution: Includes all necessary brackets and hardware for a bolt-on installation.
