Why You Need This

Race cars demand bombproof ECU mounting, and dashboard mounting simply isn't an option when space is at a premium or regulations dictate otherwise. This tube mount kit transforms standard 1.625" roll cage tubing into a secure ECU mounting point, keeping your Nexus perfectly positioned for wiring access whilst protecting it from vibration and impact damage.

We've fitted these across everything from stripped-out track day cars to full competition builds — hillclimb specials with complex cage work, circuit racers where every inch of dashboard real estate matters, and drag cars where the ECU needs protection from extreme launch forces. The precision fit eliminates the flex and movement that kills connectors over time, whilst the anodised finish withstands years of abuse. Without proper mounting, ECUs work loose, connections fail, and expensive race weekends turn into DNFs.

ECU & System Compatibility

Designed specifically for the Haltech Nexus R3 ECU, with compatibility extending to S3 and S2 variants. The mounting geometry ensures perfect alignment with all connector positions and maintains full access for tuning and diagnostics.
