Haltech Driveshaft Split Collar 2.187" / 55.55mmI.D. 8 Magnet Size: ID : 2.187" \ 55.55mm

Overview

The Haltech Driveshaft Split Collar delivers precise speed sensing for your Haltech ECU's traction control, launch control, and data logging systems. This 8-magnet design provides the resolution needed for accurate wheel speed detection in high-performance applications where factory sensors simply can't cope with big power or modified drivetrains.

Why You Need This

Factory speed sensors are the weak link in any serious performance build. They're positioned at the wheels where they're vulnerable to damage, or they're integrated into ABS systems that get deleted on track cars. The Haltech driveshaft collar solves this by moving speed sensing to a protected location on your driveshaft, giving your ECU clean, reliable signals for advanced functions like traction control and launch control.

The 8-magnet configuration provides excellent resolution for precise speed detection, crucial for responsive traction control systems on high-powered RWD builds. We see this particularly on LS-swapped drift cars, big-turbo Supras, and circuit-prepped BMWs where accurate speed sensing makes the difference between progressive power delivery and catastrophic wheel spin. The split collar design means installation without driveshaft removal — critical for cars with custom propshafts or limited access.

ECU & System Compatibility

Compatible with all Haltech Elite ECUs (550, 750, 1000, 1500, 2000, 2500) and Nexus R3/R5 systems when configured with the appropriate speed sensor input. Works seamlessly with Haltech's traction control and launch control strategies, plus provides clean speed data for logging and analysis through NSP software.
