H&R 50555573 TRAK+ Wheel Adapter 5x112 / 66.5mm Center Bore / M12x1.5 (Pair)

The H&R TRAK+ 50555573 is a hubcentric wheel adapter designed to fit Mercedes-Benz hubs featuring a 5x112 bolt pattern, 66.5mm center bore, and M12x1.5 thread pitch. Sold as a pair, these adapters allow wheels with a different bolt pattern to be fitted to the vehicle hub, expanding your wheel fitment options while maintaining a proper, factory-quality hub interface. Each adapter adds 25mm of track width per side (50mm total per axle), improving stance and stability.

Part of H&R's renowned TRAK+ lineup, these adapters are engineered and manufactured in Germany to the highest quality standards. Like all TRAK+ products, the 50555573 uses the DRA system, which bolts securely to the hub using supplied attachment hardware, with wheels then mounted using existing wheel bolts.
