H&R 605356652 TRAK+ 30mm DRA Wheel Adapter 5x112 to 5x108 (Pair)

The H&R TRAK+ 605356652 is a 30mm DRA Series hubcentric wheel adapter that converts a 5x112 bolt pattern (66.5mm center bore) vehicle hub to accept wheels with a 5x108 bolt pattern (63.3mm center bore) — such as those from Ford and Volvo. Sold as a pair. Thread pitch is M12x1.5. These adapters are engineered in Germany and precision CNC machined for an exact, factory-quality fit.

DRA Series Design:

The DRA Series adapter bolts directly to the vehicle hub using the included mounting hardware, and provides new threaded holes on the wheel-facing side for your wheel bolts. This self-contained design adds 30mm of track width per side while enabling the bolt pattern conversion — no separate wheel bolts or extended studs required beyond what is included.

Key Features:

• Bolt Pattern Conversion: Vehicle side 5x112 / 66.5mm CB → Wheel side 5x108 / 63.3mm CB
• Thickness: 30mm per adapter
• Thread Pitch: M12x1.5
• Series: DRA — bolts to hub with included hardware; no separate wheel bolts required
• Hubcentric design with full contact hub for even load force distribution and lateral support
• Made from a proprietary aluminum/magnesium alloy with higher tensile strength than 6061-T6 billet aluminum
• Hard anodized finish for superior surface hardness and corrosion resistance
• Precision CNC machined in Germany
• Compatible with OEM and aftermarket wheels
• Sold as a pair (two adapters) — sufficient for one axle

Wheel Bolt Safety Guidelines:

When installing, ensure wheel bolts do not contact or damage any brake system components, including ABS sensors. After installation, rotate the wheel by hand to verify full clearance on the inside of the hub. The wheel must spin freely without obstruction.

Minimum Engagement Turns by Thread Size:

• M12 × 1.25 — 8.0 turns (approx. 10mm load-bearing shaft length)
• M12 × 1.50 — 6.5 turns (approx. 10mm load-bearing shaft length)
• M12 × 1.75 — 6.5 turns (approx. 12mm load-bearing shaft length)
• M14 × 1.25 — 9.0 turns (approx. 12mm load-bearing shaft length)
• M14 × 1.50 — 7.5 turns (approx. 12mm load-bearing shaft length)
• 1/2" UNF — 8.0 turns (approx. 11mm load-bearing shaft length)

Bolt Head Type Reference (end digit of H&R bolt part number):
