H&R 502345715 TRAK+ Hubcentric Wheel Adapters for Ford 4/108 63.3CB (Pair)

The H&R TRAK+ Wheel Adapters (502345715) are precision-engineered hubcentric spacers designed to adapt Ford wheels with a 4/108 bolt pattern and 63.3mm center bore to a different bolt pattern, allowing you to fit wheels from a different vehicle make or model. Sold as a pair, these adapters bolt to the vehicle hub just like a standard TRAK+ spacer, but feature a different bolt pattern on the wheel-facing side for non-standard wheel fitment.

Built from a proprietary aluminum alloy with higher tensile strength than 6061-T6 billet aluminum, H&R TRAK+ adapters offer a full hubcentric contact hub — mirroring the factory hub design — for even load force distribution and superior lateral support. The result is a more aggressive stance with measurable improvements in handling and stability.

Key Features:

• Hubcentric design with full contact hub for even load distribution and lateral support
• Proprietary alloy construction — stronger and lighter than standard 6061-T6 billet aluminum
• Changes vehicle bolt pattern to allow fitment of wheels from a different make or model
• Hard anodized finish for lasting durability and corrosion resistance
• Designed for both street and performance track use
• Sold as a pair (two adapters)

TRAK+ Series Overview:

• DR Series (10–40mm): Fits between wheel and hub; requires longer wheel bolts (sold separately). Verify taper or round bolt head and shaft length before ordering.
• DRS Series (10–40mm): Fits between wheel and hub; requires swapping existing wheel studs for longer ones (included).
• DRA Series (40–60mm): Bolts to hub with special wheel bolts (included); provides new threaded holes for wheel bolts.
• DRM Series (40–90mm): Bolts to hub using existing wheel studs and special nuts (included); wheel bolts to new DRM wheel studs.

Wheel Bolt Selection Guidelines:

• New bolts must be longer than the originals by at least the width of the spacer used
• Bolt head style must match the original — taper 60° (end digit 01), round head M12/d24mm or M14/d28mm (end digit 02), round head M12/d26mm OE VAG (end digit 03), or flat head Porsche M14×1.5 (end digit 06)
• Minimum thread engagement: M12×1.25 = 8.0 turns (~10mm); M12×1.50 = 6.5 turns (~10mm); M12×1.75 = 6.5 turns (~12mm); M14×1.25 = 9.0 turns (~12mm); M14×1.50 = 7.5 turns (~12mm); 1/2″ UNF = 8.0 turns (~11mm)
• After installation, turn the wheel by hand to confirm no contact with ABS sensors or brake components — maximum clearance tolerance can be as little as 2mm on some vehicles
