Fitment, Shipping & Product Support
Is This for You?
- You're running a Jeep Wrangler, Gladiator, Grand Cherokee, or Ram 1500 Classic on a 5x127 or 5x139.7 bolt pattern and want a 20x10 8-spoke wheel at -19mm offset in gloss black with milled spoke accents — the M28 GBML 5-lug is dual-drilled for 5x127 and 5x139.7, covering Jeep and legacy Ram 1500 platforms in a single SKU.
- You want exposed lug hardware as a design element — the M28 GBML features exposed lugs, which requires spline-drive or hex cap lug nuts designed for exposed-lug applications. Standard conical or ball-seat lug nuts are not compatible. Verify lug hardware before ordering.
- You need to confirm your Jeep's trim level before ordering — Wrangler JL and Gladiator Rubicon trims use 5x139.7, not 5x127. Sport and Sahara use 5x127. Both patterns are covered by this dual-drilled wheel.
The Result
- 20x10 at -19mm offset — moderate negative offset producing 4.75" backspace. Wheel face sits outboard of the hub centerline for a wider stance on lifted and leveled builds running 33–35" tires.
- Dual-drilled 5x127 and 5x139.7 — covers Jeep Wrangler JK/JL Sport/Sahara, Gladiator Sport/Sport S (5x127), Wrangler JL Rubicon, Gladiator Rubicon, and Ram 1500 Classic DS (5x139.7) in a single wheel.
- 78.10mm hub bore — hub-centric rings required for Jeep platforms (71.5mm hub OD) and most other applications. Verify your hub OD and source the correct ring size before installation.
The M28 GBML features exposed lug pockets — the lug nuts are visible through the wheel face rather than recessed behind a cap or cover. This design requires lug nuts specifically engineered for exposed-lug applications: spline-drive or hex cap style lug nuts that seat correctly in the exposed pocket geometry. Standard conical or ball-seat lug nuts will not seat correctly and must not be used. Verify lug nut seat type and thread pitch for your specific vehicle before ordering hardware. The dual-drill 5x127/5x139.7 configuration covers the two primary 5-lug Jeep and legacy Ram bolt patterns. The 5x127 pattern is used on Wrangler JK (all trims), Wrangler JL Sport and Sahara, Gladiator Sport and Sport S, Grand Cherokee (most trims), and Commander. The 5x139.7 pattern is used on Wrangler JL Rubicon, Gladiator Rubicon, and Ram 1500 Classic (DS body, 1994–2024). The Ram 1500 Classic DS body ended production in 2024 — 2025 and 2026 Ram 1500 is the New Body (DT) platform using 6x139.7, which does not fit this wheel. Hub-centric rings are required for Jeep applications (71.5mm hub OD). TPMS sensors are sold separately. Once tires are mounted, wheels are non-returnable.

Installation Notes
- Exposed lug design — standard lug nuts are NOT compatible. Use spline-drive or hex cap lug nuts designed for exposed-lug applications. Verify lug nut seat type and thread pitch before ordering hardware.
- Hub bore is 78.10mm. Hub-centric rings are required for Jeep platforms (71.5mm hub OD) and most other applications. Verify your hub OD and source the correct ring size before installation.
- Verify brake caliper clearance before mounting tires. -19mm offset on a 10" wide wheel produces 4.75" backspace.
- Wrangler JL and Gladiator: confirm trim level before ordering — Sport/Sahara uses 5x127 holes, Rubicon uses 5x139.7 holes.
- TPMS sensors sold separately.
- Once tires are mounted, wheels are non-returnable.
Engineering Question: What is your vehicle's year, make, model, and trim level, and what is your current lift height and tire size? Confirm your hub OD — hub-centric rings are required for Jeep (71.5mm) and most 5-lug applications. Also confirm your lug nut seat type — this is an exposed-lug wheel and standard lug nuts are not compatible. For Wrangler JL and Gladiator, confirm Sport/Sahara (5x127) or Rubicon (5x139.7).
