Is it time to replace your race suit? Let’s get you track-ready. 
Fitting an aftermarket wheel needs a hub, and this Momo Alfa Romeo Giulietta Steering Wheel Boss is the vehicle-specific part for the job. The splines match the column on this model, and the depth sets the wheel where it should sit relative to the stalks and the dash.
Machined from aluminium by MOMO, drilled for 6x70mm PCD wheels, and supplied with the fixings required to complete the installation.

What a boss kit does
An aftermarket steering wheel will not bolt to a car’s column on its own. The hub sits between the two, matching the column splines on one side and the wheel bolt pattern on the other. It also sets how far the wheel sits from the dash, which affects your reach to the stalks and the clearance to your knees.
This one is a collapsible design. A collapsible hub keeps the column’s designed collapse behaviour, which is the safer choice for a car that still sees regular road use.
If the car has a driver airbag, that airbag is lost when the standard wheel comes off. Disconnect the battery and leave the system to discharge before you start, and get the airbag handled properly rather than leaving it hanging off the column. Tell your insurer the car has been modified.
Fitting the Momo Alfa Romeo Giulietta Steering Wheel Boss
Centre the road wheels before you take the old wheel off and mark the column so the new wheel goes back on straight. The hub bolts to the column first, then the wheel bolts to the hub. Torque the centre nut properly, it is the only thing holding the wheel on.
The horn connection carries through the hub. Wire it before you bolt the wheel on, because getting to it afterwards means taking the wheel back off.
Once it is together, check the wheel clears the indicator and wiper stalks through full lock in both directions, and that nothing catches on the way round.
Momo Alfa Romeo Giulietta Steering Wheel Boss questions
Does the Momo Alfa Romeo Giulietta Steering Wheel Boss come with fixings?
Yes. The kit is supplied with the screws needed to mount the wheel to the hub. You will reuse the column nut from the standard wheel.
Will the Momo Alfa Romeo Giulietta Steering Wheel Boss fit any steering wheel?
It takes wheels on a 6x70mm pattern. Check the back of your wheel before ordering if you are not sure which you have.
Do I lose the airbag?
Yes. Removing the standard wheel removes the driver airbag on any car fitted with one. Disconnect the battery first, have the airbag dealt with properly, and let your insurer know the car has been modified.
Will the horn still work?
The horn contact carries through the hub, so it works with a wheel that has a horn push. Wire it up while the wheel is off.
Is this the right hub for my Alfa Romeo Giulietta (1981 Onward)?
It is machined for this application. If your car sits near a model year change or has had a column replaced, send us the registration and we will check it before you order.
