Pre-pressed head stem and bottom bearing

Whilst we always recommend that our components are installed by a qualified mechanic, all the hard work has already been done. The kit ensures that the head stem and bottom bearing are pressed on, making the installation a breeze.

We’ve also added two helicoiled mounting holes either side, along with adjustable steering stoppers to suit the needs of your build.

Excellent kit

Perfect fit and looks very good

Quality Parts and Communication

The kit itself is a great design, very high quality. Installation was made a breeze by Jax Garage, everything bolted on and was rolling within minutes. Additionally Jas worked with me to produce a few extra bits to make the kit exactly what I wanted for my build. Great parts, even better guy to work with in Jas. Can't recommend Jax Garage enough.
