Description

Haltech Driveshaft Split Collar 2.125 Inch / 53.98mm ID 8 Magnet

This 8 magnet split collar is the clean way to add driveshaft RPM measurement to a drag or race car. It clamps around a 2.125 inch (53.98mm) driveshaft, rear-end yoke, or coupler and works with a hall effect sensor to feed accurate driveshaft speed into your ECU. The two-piece split design means no driveshaft removal: it bolts around the shaft in place using the included Allen key.

Driveshaft RPM is the input that unlocks serious race control strategies, most notably Advanced Torque Management on the Haltech Elite 2500 T and Nexus platforms, plus wheel slip based traction control and data logging for chassis tuning.

Key Features

  • 8 evenly spaced magnets for a high resolution driveshaft speed signal
  • Two-piece split collar design installs without removing the driveshaft
  • Machined for balance and secure clamping at drag racing shaft speeds
