FAQ
What is the bolt pattern on a Chevrolet Avalanche?
The Chevrolet Avalanche uses a 6x139.7 bolt pattern with a 78.1mm center bore across every Avalanche variant in our database (2 guides, 2002–2007).
What is the Chevrolet Avalanche center bore?
The hub-centric center bore is 78.1 mm. Aftermarket wheels should match this bore or use hub-centric rings so the hub, not the bolts, carries the load.
Do all Chevrolet Avalanche years share the same wheel fitment?
The bolt pattern and center bore are the same across the years we cover, but OE wheel width and offset differ by trim, so check the exact model line before choosing an aftermarket size.
Which forged wheels fit the Chevrolet Avalanche?
Any wheel drilled 6x139.7 with a 78.1mm hub bore in the offset range shown on the model guide. ANKUSI forges wheels to order for this exact specification, in 14–24 inch diameters, so no adapters or hub rings are needed.
