We introduce an updated and advanced version of our Mononut adapter kit, that includes a hub adapter, drive pins screws, centre nut and special wrench.

The purpose of our ARS Mononut Adapter is to convert a normal 4 or 5 bolt hubs to centre lock hub. The first pattern, 4 or 5 bolts, matches the vehicle hub, while the second pattern matches the wheel centring specifications. 

The Hub Adapter and Drive Pins are machined from a high-grade steel while the Centre Nut is made from aerospace aluminium grade, combined with a hard anodization finish for the ultimate in strength and durability.

Also, the safety clips were updated to a more innovative solution: we incorporated a built-in Automatic Retaining System (ARS) that snaps into the top-crown of the nut to prevent it from loosening, and keep the wheels secured in any condition. 

After the Mononut Adapter is installed on to the hub over the rotor hat and tightened down using the bolts or nuts included on the kit, which also serve as drive pins, the wheel is fitted and tightened with the centre nut using the supplied wrench. 

Other benefits and features are:

- Quicker wheel locking than our previous adapter

- Easier installation/fixation

- Wheel Auto-centring

- Plate thickness from only 5mm

- Adaptable to any vehicle

- Compact, only 94mm protruding from mounting face, depending on the wheel specs

- 50% lighter than our previous adapter. From only 1.2Kgs
