Why these outperform generic spacers

Stronger than Cast — Machined from 6061-T6 Billet

  • 6061-T6 aluminum: Toughness and fatigue resistance suited for working trucks.
  • True hub & wheel centering: 116.7→121.2 mm piloting reduces vibration and shares load correctly.
  • Precision machining: Tight runout/concentricity for highway-speed stability.
  • High-strength hardware: Premium studs and nuts spec’d to meet or exceed OEM grade.
  • OEM geometry preserved: Same-pattern 8×6.5″ keeps correct mating alignment.
Install Notes
  1. Verify fitment: Confirm 8×6.5″ (8×165.1 mm) PCD, M14×1.5 studs, and 116.7 mm hub bore on your vehicle.
  2. Confirm wheel bore: Ensure your wheels have a 121.2 mm (≈121.2–121.3 mm) center bore to seat on the adapter lip.
  3. Prep hub: Safely lift/secure vehicle; remove wheel. Clean hub face and center bore of rust/paint/debris.
  4. Test-fit adapter: Slide adapter onto hub; verify full, even seating (no gaps).
  5. Secure adapter: Install nuts on factory studs; tighten in a star pattern to the manufacturer’s torque spec.
  6. Mount wheel: Place wheel on adapter studs; install lug nuts and tighten in a star pattern to spec.
  7. Spin & clearance check: Rotate by hand to verify no contact with calipers, suspension, or fenders.
  8. Re-torque: After 50–100 miles, re-torque adapter and wheel nuts to spec; check periodically.

Follow the torque specs and seat style (cone/flat) required by your wheels and owner’s manual.

Fits my 2026 civic sport perfect!
Size: AF151
No issues, fitment is perfect. Great quality for an excellent price. Dealer wanted like $24 for a basic one. Nah I'm good I'll just go on Amazon and get it for $8. Took 30 seconds from start to finish can't get any easier.

Fits well and installs easily.

This filter looked about the same as the OEM filter. It installed in about a minute. The quality appeared to be fine. It was protected in a cardboard box. It fit my 2014 Subaru Outback perfectly. I just installed it an hour ago so I don’t have any long term observations about longevity or effectiveness. I can’t see any reason why it would not work as well as the original, it seemed identical.

Great fit and quality
Size: AF113
Not a complicated product, but after going to 2 different auto parts stores and this not being in stock, Amazon to the rescue. Arrived the next day and the quality is definitely on par with “store brand” ones from retailers. Definitely cheaper as well.
