Why You Need This

Modern Haltech ECU functions depend on accurate vehicle speed data — from transmission shift scheduling in 4L60E and 4L80E swaps to traction control mapping in high-power builds. The split collar design eliminates the need to disconnect drivelines during installation, a massive advantage over pressed-on alternatives that require complete drivetrain disassembly. The 8-magnet configuration provides excellent signal resolution, crucial for responsive automatic transmission control and precise data logging.

This 46mm bore suits most popular driveshaft applications including Ford 9-inch rear ends, GM 12-bolt setups, and many European drivetrain conversions. Without proper VSS sensing, your Haltech ECU cannot execute transmission shift strategies, calculate gear-dependent boost or timing maps, or provide accurate speed-based traction control intervention. We regularly fit these during LS swap projects where the factory VSS location is eliminated but ECU transmission control is retained.

ECU & System Compatibility

Compatible with the full Haltech Elite and Nexus range including Elite 550, 750, 1000, 1500, 2000, and 2500 ECUs, plus Nexus R3 and R5 systems. VSS input configuration is handled through NSP software with selectable pulse-per-revolution settings to match your specific application requirements.

What's in the Box

• Installation hardware
• Technical documentation

Complete Your Build

Most customers installing driveshaft speed sensing also require a compatible Hall Effect sensor and extension loom to complete the VSS circuit back to their Haltech ECU. Our technical team can recommend the correct sensor positioning bracket and wiring components based on your specific driveline configuration. With UK stock holding and extensive experience in drivetrain speed sensing applications, we'll ensure your VSS setup delivers the accuracy your Haltech ECU demands for optimal transmission and traction control performance.
