H&R 506556013 TRAK+ Wheel Adapters 5/112 to 5/112 Mercedes 66.5mm CB 14x1.5 (Pair)

The H&R 506556013 TRAK+ Wheel Adapters are hubcentric wheel adapters designed specifically for Mercedes-Benz applications, featuring a 5/112 bolt pattern, 66.5mm center bore, and 14x1.5 thread pitch. Sold as a pair, these adapters allow fitment of wheels with a different bolt pattern by changing the vehicle's bolt pattern on the wheel side of the spacer — making non-standard wheel fitment possible while maintaining a precise, hubcentric fit.

Unlike standard wheel spacers, TRAK+ Wheel Adapters mount to the vehicle hub exactly like a traditional spacer but present a different bolt pattern on the outboard face. This hubcentric design ensures the adapter seats directly on the vehicle hub for a secure, vibration-free fit. Available in thicknesses from 20mm to 25mm, these adapters also widen the vehicle's track for improved stance, handling, and lateral stability.

Key Features:

• Hubcentric design — seats precisely on the vehicle hub for a secure, wobble-free fit
• Bolt pattern: 5/112 vehicle side | 66.5mm center bore | 14x1.5 thread
• Sold as a pair (two adapters included)
• Proprietary aluminum/magnesium alloy construction — up to 70% lighter than comparable steel products
• Hard anodized finish for long-lasting durability and corrosion resistance
• Maximizes track width for improved lateral stability and lowered roll center
• Suitable for use with winter snow tire and wheel setups

Wheel Bolt Safety Guidelines:

When ordering replacement wheel bolts for use with these adapters, new bolts must be longer than the originals by the width of the adapter. The bolt head style must match your existing bolts. Use the following minimum engagement reference:

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

Always verify that wheel bolts do not contact or damage ABS sensors or other brake components. Rotate the wheel by hand after installation to confirm full clearance. Note: maximum tolerance on some vehicles (such as Mercedes rear axles) may be as little as 2mm.

Bolt Head Type Reference (when ordering bolts):

• Taper 60° seat — 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 for Porsche OE wheels M14 x 1.5 — end digit 06
