5x114.3 to 5x120 Hubcentric Wheel Adapters 20mm for Honda Odyssey Pilot Acura MDX CL, M12x1.5 Studs, 64.1mm Hub Bore, Set of 2

5x114.3 to 5x120 Hubcentric Wheel Adapters for Honda and Acura – 20 mm, Set of 2

These BDFHYK hubcentric wheel adapters convert a compatible 5x114.3 Honda or Acura vehicle hub to a 5x120 wheel-side pattern. Each adapter is approximately 20 mm thick, so the wheel mounting surface moves outward by 20 mm per side. The design is intended for selected applications using a 64.1 mm vehicle-side hub bore and M12x1.5 hardware, including applications listed for Odyssey, Pilot, MDX, and CL.

The conversion pattern is only one part of fitment. Before ordering, confirm the exact model year, hub diameter, wheel center bore, thread pitch, lug-seat style, wheel offset, brake clearance, wheel-pocket depth, and available fender space. Measure both axles when correcting only the front or rear because wheel position and available clearance can differ.

Vehicle-Side and Wheel-Side Fitment

• Vehicle-side bolt pattern: 5x114.3.
• Wheel-side bolt pattern: 5x120.
• Adapter thickness: approximately 20 mm per side.
• Vehicle-side bore: 64.1 mm as listed.
• Thread configuration: M12x1.5.

Common Fitment Scenarios

The 20 mm adapter may be used to mount a compatible 5x120 wheel on a verified 5x114.3 hub without replacing the hub assembly. It may also create additional inner clearance around a strut, coilover, upper control arm, brake component, or inner tire area. Because the wheel moves outward, outer fender and liner clearance become tighter. Full-lock steering and suspension-compression checks are required before the vehicle is driven normally.

Construction and Package

• Forged 6061-T6 aluminum construction.
• Black anodized surface for corrosion and wear resistance.
• Grade 10.9 mounting hardware as listed.
• Two adapters for one axle, plus listed installation accessories.

20 mm or 1 Inch?

The 20 mm option keeps the wheel approximately 5.4 mm farther inward per side than the 1 inch version. It is generally the better starting point when less outward movement is needed, but it still requires sufficient room for the wheel, brakes, studs, and hardware. Neither thickness guarantees that a specific wheel or tire will clear the fender or suspension.

Fitment Checks Before Ordering

• Confirm a 5x114.3 vehicle hub, 64.1 mm hub diameter, and M12x1.5 hardware.
• Confirm the intended wheel is 5x120 and fits the wheel-side centering lip.
• Measure wheel offset and calculate the new outward wheel position.
• Check rear wheel-pocket depth and any original stud protrusion.
• Verify lug-seat style, brake-caliper clearance, fender clearance, and tire clearance at full lock and compression.

Installation and Maintenance

Clean the hub face and remove rust or debris before installation. The adapter must sit completely flat with no gap. Tighten the adapter hardware in a star pattern with a calibrated torque wrench, then mount the wheel using the correct seat style and torque specification. Do not stack adapters or spacers. Recheck torque after the initial driving period and inspect the assembly whenever the wheels are removed.
