D20B Dually Inner

Gear Off Road D20B Dually Inner: the rear inner wheel for your dually build

The Gear Off Road D20B Dually Inner is the inner half of a dually rear setup, built to sit behind the outer wheel on a one-ton truck so the pair reads as a matched set. It's a monoblock wheel with a deep-offset dished face designed to tuck inside the fender and mate cleanly to its outer counterpart. If you're running a dually and need the hidden inner to finish the look, this is the piece that does it. It sits within the broader Gear Off Road lineup of truck and off-road wheels.

Sizes and fitments stocked

This wheel is stocked in a single, focused spec built for dually rears. Every version is 20x8.25 at +115 offset — the high offset is what pulls the inner wheel into position on a dual-rear axle. Bolt patterns cover the common heavy-duty layouts:

Match this inner to your outer wheel and confirm the numbers against your truck with the fitment calculator.

Finish

The D20B Dually Inner comes in Gloss Black, which keeps the hidden inner discreet and consistent with a blacked-out dually stance. You'll find more dark options across the black Gear Off Road wheels selection.

Price and who it suits

Pricing runs from about $296 to $297 per wheel, so it slots in as the inner component of a dually package for anyone building out a 3500- or 450-class truck. It's aimed squarely at dually owners — not a standard single-rear-wheel fitment.

If a single inner isn't what your build needs, look at the standard off-road faces in the same family: the one-piece 774SB, the milled-accent 773MB and its plainer 773B, the 772MB and 772B pair, or the 770B for a simpler black face. These are single-rear designs rather than dually inners.
