Wheel Spacers Adapter 4x100 and 4x114.3 to 4x108 Bore 71 mm 20 mm

4x100 and 4x114.3 to 4x108 adapter wheel spacers: fit 4x108 wheels on your car

This adapter wheel spacer converts a 4x100 or 4x114.3 hub to a 4x108 bolt pattern. Sold as a pair in 20 mm, it allows you to fit 4x108 wheels (a typical fitment for Peugeot, Citroën, or older generation Ford vehicles) on a car that does not have this bolt pattern from the factory, while slightly widening the track.

Why choose this 4x108 bolt pattern adapter

• Dual hub-side bolt pattern: the same spacer accepts a 4x100 or 4x114.3 hub, covering a large number of small city cars and compact cars.
• 4x108 output: four pressed studs at the correct bolt pattern to accept a 4x108 wheel.
• 71 mm bore: a large center hole that fits most hubs in this family.
• Machined 6061-T6 aluminum: lightweight and strong, with a raw silver finish.
• Class 10.9 studs: M12x1.5 pressed studs, supplied with open-ended nuts.

4x100 to 4x108 wheel adapter: what is it used for

A bolt pattern adapter is a wheel spacer where the two sides have different bolt patterns. It is used to reuse wheels from another vehicle, for example 4x108 wheels on a 4x100 car, without having to re-drill them. It meets searches for "4x108 wheel spacer", "4x100 wheel spacer", and "4x100 to 4x108 wheel adapter". Since it does not center the wheel on its own hub, the use of wheel-specific centering rings is recommended.

Technical specifications

Vehicle side: 4x100 or 4x114.3 bolt pattern. Wheel side: 4x108 bolt pattern. 71 mm bore. M12x1.5 class 10.9 studs, nuts included. 20 mm thickness per adapter. Material: machined 6061-T6 aluminum, silver finish. Packaging: 2 adapters.

Installation and safety

If the hub studs protrude beyond the thickness of the adapter, they must be shortened so that the wheel sits flush. Tighten the adapter onto the hub with the supplied nuts, then the wheel onto the adapter, to the manufacturer's torque and in a star pattern; re-tighten after 50 to 100 km. Check wheel compatibility (bore, offset, lug seat) and ensure the tires do not protrude, as noted during the technical inspection. No approval is stated; professional installation is strongly recommended.

Frequently asked questions

Can I fit 4x108 Peugeot wheels on a 4x100 car?
Yes, that is what this adapter is used for, provided that the wheel offset and diameter remain compatible with your fenders and brakes.

Are centering rings required?
They are recommended: the 71 mm bore does not center the wheel, and the rings reduce vibrations.

What thickness?
20 mm per adapter, meaning 40 mm of extra track per axle.

Are the nuts supplied?
Yes, M12x1.5 open-ended nuts, suitable for pressed studs.

Reuse your 4x108 wheels without re-drilling: order the pair of 20 mm adapters.
