KDN Performance Shift-Cut Knob

Fast. Precise. Affordable.

The KDN Shift-Cut Knob is the perfect entry point into clutchless shifting for dogbox and sequential transmission setups. Designed to deliver the same function as a strain-gauge knob, it triggers igniton or fuel cuts through your ECU, but at a fraction of the cost.

Built in-house and engineered for wide-open throttle (WOT) shifts, the knob uses a dual microswitch system that activates instantly when you apply force during a shift. This signal momentarily cuts torque, allowing for smooth, clutchless upshifts without lifting off the throttle.

This microswitch-based design offers rock-solid reliability, simple wiring, and consistent performance, all in a CNC-machined aluminum housing made to withstand years of hard racing.

Features:

• Dual internal microswitches for reliable, redundant signal activation

• Enables clutchless upshifts under full throttle

• CNC-machined from aluminum, no plastic components

• 100% Canadian-made

• Includes Deutsch connector with 6" pigtail

• Compatible with standalone ECUs and KDN Shifters

• M12×1.75 , M10X1.50 AND 3/8-16 thread pitch are available

• Available in plain or knurled finish

Wiring Guide:

• Pin 1: Signal IN – accepts Ground, 5V, or 12V input (do not exceed 12V; 16V will damage the switches)

• Pin 2: Signal OUT – connects to ECU trigger input
  (Switches are wired in parallel for redundancy and can be used in either direction depending on ECU setup.)

Built in-house. Built to perform.
