Wheel Cap Fitment Guide
Wheel Cap Fitment Guide
Use this guide to find the right AWM cap based on center bore, wheel make and model, lug pattern, attachment method, and engraving requirements.
Check attachment method first: Our Set Screw caps are intended for wheels with a straight-through bore. KMC IMS and Riot replacement caps bolt onto the front face of the wheel using existing threaded holes and original hardware. These are different attachment systems; a matching bore or lug pattern alone does not establish fitment.
Step 1: Know Your Center Bore (mm)
For Set Screw caps, confirm the bore diameter in millimeters and that the wheel has a straight-through bore. Check your wheel manufacturer's specifications or measure the opening with calipers. For model-specific replacement caps, also confirm the exact wheel model and attachment system.
| Center Bore | Cap Model | Price (from) | Shop |
|---|---|---|---|
| 87.1 mm | AWM Billet Aluminum Wheel Cap – 87.1mm | $100.00 | View Cap → |
| 95 mm | AWM Billet Aluminum Wheel Cap – 95mm | $100.00 | View Cap → |
| 108 mm | AWM Billet Aluminum Wheel Cap – 108mm | $110.00 | View Cap → |
| 110 mm | AWM Billet Aluminum Wheel Cap – 110mm | $110.00 | View Cap → |
| Volk TE37-XT (Raptor-specific) | AWM Billet Wheel Caps – 17" TE37-XT Raptor Fitment | $100.00 | View Cap → |
Step 2: Match Your Wheel Make & Model
These model-specific replacement caps must match your wheel. KMC IMS and Riot caps mount to the existing threaded holes on the front face of the wheel using original hardware. They do not use our Set Screw attachment system.
| Wheel Brand / Model | Attachment Method | Compatible Models | Price (from) | Shop |
|---|---|---|---|---|
| KMC IMS | Face-Bolted: existing front threaded holes and original hardware | KMC IMS – 6x135, 6x139.7 | $100.00 | View Cap → |
| KMC Riot | Face-Bolted: existing front threaded holes and original hardware | KMC Riot – 6x135, 6x139.7 | $100.00 | View Cap → |
| Method Bead Grip | Snap-In (O-ring, retention groove) | MR701, MR703, MR704, MR705, MR707, MR708, MR708 HD | $90.00 | View Cap → |
| Volk TE37-XT (17") | Push-Through / Hub-Centric | Ford Raptor, Bronco Raptor on 17" TE37-XT | $100.00 | View Cap → |
Step 3: Confirm Your Lug Pattern
Confirm the lug pattern specified for the cap and choose the matching variant where offered. Also confirm wheel model, bore, and attachment method. A matching lug pattern alone does not establish compatibility.
| Lug Pattern | Cap |
|---|---|
| 6x139.7 or 5x139.7 | 108mm Set Screw cap, select the matching lug-pattern variant |
| 5x150 | 110mm Set Screw cap |
| 6x135 or 6x139.7 | KMC IMS and KMC Riot replacements, match the wheel model and existing front threaded holes |
For the 87.1mm and 95mm caps, confirm the requirements on the product page or contact AWM before ordering if your fitment is uncertain. Check wheel specifications for your exact lug pattern rather than relying on vehicle name alone.
Step 4: Choose Your Attachment Method
Match the cap to the way your wheel accepts and retains its center cap. Set Screw and face-bolted caps are separate designs.
| Attachment Method | How It Works | Caps Using This Method |
|---|---|---|
| Set Screw | Intended for wheels with a straight-through bore. Uses the included 3 set screws and 3 jam nuts. Does not bolt into the front-face threaded holes used by the KMC replacement caps. | 87.1mm, 95mm, 108mm, 110mm |
| Face-Bolted | Bolts onto the front face of the wheel using its existing threaded holes and original hardware. Different from our Set Screw caps for straight-through bores. | KMC IMS and KMC Riot replacements |
| Snap-In (O-Ring) | Included O-ring seats into the wheel's existing retention groove. Replacement for factory snap-in plastic caps. | Method Bead Grip replacement |
| Push-Through / Hub-Centric | Installs from the rear of the wheel. Functions as both center cap and hub-centric ring. Specific to the TE37-XT Raptor fitment. | Volk TE37-XT 17" (Raptor/Bronco Raptor) |
Step 5: Select Your Engraving Option
Most AWM caps are available in three engraving configurations. Engraving is machined directly into the cap face, not a sticker, badge, or insert.
- No Engraving / Blank – Clean face, no logo. Same price as AWM Logo on most caps.
- AWM Logo – Subtle engraved AWM mark. Standard pricing.
- Custom Engraving – Your shop logo, team mark, or build name machined into the face. Minimum order of 4 caps. Must use the custom engraving request form, rather than adding to cart directly. Pricing and a cost estimator are on that page.
Custom engraving adds $25 over standard pricing on most cap models.
