H&R 406556013 TRAK+ Wheel Adapter Set for Mercedes 5/112 Bolt Pattern (Pair)

The H&R 406556013 TRAK+ Wheel Adapters allow you to fit wheels with a different bolt pattern to your Mercedes-compatible hub (5/112, 66.5mm center bore, 14x1.5 thread). Sold as a pair, these hubcentric adapters change the vehicle's bolt pattern on the wheel-facing side, enabling non-standard wheel fitment while maintaining the precise, hubcentric fit H&R is known for. Available in thicknesses ranging from 20mm to 25mm.

What Are TRAK+ Wheel Adapters?

H&R TRAK+ Wheel Adapters mount to the vehicle hub just like a standard TRAK+ spacer, but feature a different bolt pattern on the outboard (wheel) side. This allows wheels from a different vehicle make or model to be properly fitted. Like the DRM Series spacers, these are hubcentric — meaning they locate precisely on the hub for a secure, rattle-free fit.

Key Features:

• Hubcentric design — seats precisely on the vehicle hub for proper centering and vibration-free fitment
• Bolt pattern adaptation — changes the outboard bolt pattern to allow non-OEM wheel fitment
• Mercedes-specific specs — 5/112 bolt pattern, 66.5mm center bore, 14x1.5 thread pitch
• Sold as a pair — includes two adapters per set
• Proprietary aluminum/magnesium alloy construction — up to 70% lighter than a comparable steel product
• Hard anodized finish — provides a tough, corrosion-resistant surface
• Maximizes track width — improves lateral stability and lowers roll center for enhanced handling
• Suitable for winter use — compatible with snow tires and dedicated winter wheel sets

Wheel Bolt Guidelines (when ordering replacement bolts):

• New bolts must be longer than originals by the thickness of the adapter used
• Bolt head style must match existing hardware — verify taper or round head type before ordering
• Taper 60° — end digit 01
• Round head M12/d24mm or M14/d28mm — end digit 02
• Round head M12/d26mm (e.g. OE VAG wheels) — end digit 03
• Flat head Porsche OE M14×1.5 — end digit 06

Minimum Wheel Bolt Engagement (Safety Requirements):

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

After installation, always rotate the wheel by hand to confirm clearance on the inside of the hub. Ensure wheel bolts do not contact any brake components or ABS sensors. Note: maximum tolerance on some vehicles (e.g. Mercedes rear axle) may be as little as 2mm.
