⚙️ New Product Drop from 3J Driveline ⚙️
We’ve been busy behind the scenes and this one has been earning its keep for a while...
Introducing our newly manufactured 3rd/4th gear synchro rings for the Ford Type-E / Rocket gearbox—now upgraded with a carbon fibre friction layer.
What does that mean for you?
👉 Improved durability
👉 Smoother, more precise shifts
👉 Built to handle serious use
These aren’t fresh off the drawing board either—
They’ve been tried and tested in rally gearboxes for the past two years, so they are well past the prototype stage and proving themselves where it really counts. 🏁
Now available from the 3J Driveline webshop. ➡ https://www.3jdriveline.com/webshop/spares-and-accessories/gear-selection/3rd-4th-ford-rocket-type-e-synchro-ring-with-carbon-layer/
