Hub Bore and Bolt Pattern Adapter System 4B – Fixed System with Dual Centering and Threaded Inserts
Adapters from System 4B are firmly bolted to the vehicle and ensure optimal driving performance thanks to their dual centering. The adapters are mounted to the vehicle using the supplied mounting hardware. The wheel is then mounted using the original wheel bolts in the threaded inserts of the adapter. In System 4B, the threads are reinforced with steel thread inserts to reduce wear. No longer bolts are required for System 4B spacers – in most cases, the system is plug-and-play.
- Spacer thickness: Indication in mm per wheel
- Packaging unit: 2 pieces (= 1 axle)
- Mounting material included
- Price: in EUR incl. stat. VAT
