The long awaited Ford C4 linear sensor gear position kit is back and in stock.

Until now there’s been no kit to fit the linear sensor to the Ford C4 automatic gearbox. I myself have a C4 in my turbo Barra XP falcon, I use the Haltech ecu and IC7 gauge display. The IC7 has a function where it can display the gear position on the screen. Having a gear shift input into the e

Have you done a Barra engine conversion and not running power steering in your project?  I actually built this kit of mine 6-7 years ago when putting the Barra into my XP Falcon and of course the internet experts said it wouldn’t work…😂 My kit has worked flawlessly all these years so tho

Looking for a linear sensor but I don’t make a bracket kit to suit your particular gearbox?
Because in reality I don’t really have the time to source every model of gearbox just to fab brackets.
Ideal for racers who want to log and analyze the linear position of moving components like suspension travel, steering angle or gearbox position.

Now most car builders, enthusiasts and tuners are a creative bunch and aren’t afraid to fab some simple brackets.
I’m now offering the linear sensor and harness by itself to purchase.

Kit includes:
Linear position sensor -
13mm diameter, 50mm travel.
167mm closed between mounting holes.
DTM Deutsch connectors.
+ 600mm of additional harness.

Suits all ecu’s with a spare AVI.
Ingress protection rating of IP65

$155 plus $15 postage.

Replaces your now rotten old paper cone speaker.

Speaker installs from the top which means you don’t have to disassemble your dash in order to install.
Speaker is a 160w max, 4x6”, 4ohm, 3 way coaxial speaker, a lot better than your original 20 watt speaker!!
