Product Description

The Haltech HT-039067 Tube Mount Kit is purpose-built for mounting the Nexus R3 (or similarly sized Nexus ECUs such as S2/S3) securely to 1.625" (41.275 mm) tubing in custom or motorsport builds. Crafted from CNC-machined 6061 aluminum and finished in black anodizing, this mounting kit combines precision, strength, and aesthetics. It provides a clean, robust solution for roll cages, chassis rails, or structural tubing where conventional flat mounting isn't possible or desired.

The kit includes two tube clamps that cinch to your chassis tubing and a base bracket sized to hold the ECU firmly, allowing you to route wiring efficiently while maintaining vibration resistance. It supports multiple orientations for flexibility in cable exit paths. This mount is ideal for race cars, drift builds, engine swaps, roll cage setups, or any custom environment where a traditional chassis mounting point is unavailable.

Ensure your vehicle's tubing matches the 1.625" (41.275 mm) specification before purchasing. For other tube diameters, Haltech offers alternate kits (e.g. HT-039065 for 1.25"). Use in conjunction with appropriate wiring and environmental protection to maintain ECU reliability over time.
