Grid Off-Road Center Cap Buying Guide

Grid Off-Road wheels are built for truck and SUV owners who want serious off-road capability with a clean, modern aesthetic. Their caps are exclusively black — available in both gloss and matte — and use a straightforward "GD" part numbering system that makes finding replacements easy.

Grid Off-Road Cap Part Numbers

Grid caps follow a "GD-[model]-CAP" naming convention with a cross-reference code that encodes the bore size and outer diameter:

  • GD-8-CAP / C8046L213 (Gloss Black) — Gloss black cap for Grid model 8 series wheels, 80mm bore, 46mm depth, 213mm outer diameter.
  • GD-8-CAP / C8046L213 (Matte Black) — Same dimensions as the gloss version, matte black finish.
  • GD-56-CAP / C6020L197 (Gloss Black) — Gloss black cap for Grid model 56 series, 60mm bore, 20mm depth, 197mm outer diameter.
  • GD-56-CAP / C6020L197 (Matte Black) — Matte black version of the GD-56 cap.

Pro tip: The cross-reference code (e.g., C8046L213) encodes the bore size as the first two digits after "C" — "80" = 80mm bore, "60" = 60mm bore. This makes it easy to verify fitment by bore size alone.

Gloss Black vs. Matte Black Grid Caps

Grid Off-Road offers both gloss and matte black across their cap lineup. Gloss black suits builds with polished or two-tone accents, while matte black is the more popular choice for all-black or stealth truck builds. Both finishes use the same snap-in retention system and bore dimensions — the only difference is the surface finish.

How to Find the Right Grid Cap

  1. Identify your Grid wheel model — Grid model numbers are typically 2-3 digits (e.g., GD-8, GD-56). Check the back of the wheel or your purchase receipt.
  2. Choose gloss or matte black — Match your existing wheel finish.
  3. Verify the bore size — Use the cross-reference code or measure the center bore in millimeters.
  4. Check the outer diameter — Grid caps vary in outer diameter (197mm vs. 213mm). The outer diameter affects how the cap sits flush with the wheel face.
