H&R 1655571665 TRAK+ DR Series Hub Adapter 8mm 57.1 to 66.5 Center Bore Pair

The H&R TRAK+ DR Series Hub Adapter (MPN: 1655571665) is an 8mm hubcentric wheel adapter sold as a pair, designed to convert a 57.1mm vehicle center bore to a 66.5mm wheel center bore. This allows fitment of wheels with a larger center bore while maintaining proper hub-centric alignment for smooth, vibration-free operation.

Drilled for both 5x100 and 5x112 bolt patterns, these adapters are built from H&R's proprietary high-grade aluminum alloy — engineered to exceed the tensile strength of standard 6061-T6 billet aluminum while remaining significantly lighter. Each adapter features a full-contact hubcentric design that mirrors the factory hub, ensuring even load force distribution and lateral support under all driving conditions.

Key Features:

• Converts 57.1mm vehicle center bore to 66.5mm wheel center bore
• 8mm thickness per adapter — sold as a pair (two adapters)
• Compatible with 5x100 and 5x112 bolt patterns
• Hubcentric design for precise fit and elimination of vibration
• Manufactured from proprietary high-strength aluminum alloy
• Hard anodized finish for corrosion resistance and durability
• 100% made in Germany
• Note: Lug bolts are not included and must be purchased separately. Add the adapter thickness to the OE bolt length to determine the required bolt length (e.g., 27mm OE bolt + 8mm adapter = 35mm minimum bolt length)

The DR Series is part of H&R's TRAK+ line of wheel spacers and adapters, offering 10–40mm of track widening. DR Series adapters fit between the wheel and hub and require longer wheel bolts ordered separately — verify bolt seat type (taper or round) and shaft length before ordering.
