Chevrolet Silverado 2500HD Bolt Pattern

Catalog records for the Chevrolet Silverado 2500HD use two bolt patterns: 8×165.1 for 2001–2006, 2008 and 8×180 for 2007, 2009–2023.

Yes. Catalog records show two bolt patterns: 8×180 (2007, 2009–2023); 8×165.1 (2001–2006, 2008). Choose the pattern that matches the vehicle you have.

Generation, year range, and configuration can change the hub. Catalog records for the Chevrolet Silverado 2500HD list 8×180 for 2007, 2009–2023 and 8×165.1 for 2001–2006, 2008. Do not assume later years match earlier years.

Catalog records show 8×180 for 2007, 2009–2023 (16 years).

Catalog records show 8×165.1 for 2001–2006, 2008 (7 years).

Catalog records show 8 lugs on 8×180 (2007, 2009–2023); 8 lugs on 8×165.1 (2001–2006, 2008).

8×180 means 8 lug positions on a 180 mm pitch circle. The first number is lug count; the second is the pitch circle diameter in millimetres.

8×165.1 means 8 lug positions on a 165.1 mm pitch circle. The first number is lug count; the second is the pitch circle diameter in millimetres.

Catalog records show 124.1 mm.

Catalog records show M14 x 1.5.

Catalog records for the Chevrolet Silverado 2500HD list lug nuts with M14 x 1.5 thread.

Yes. 8×165.1 and 8×6.5 describe the same bolt circle: 8 lugs on 165.1 mm (6.5 in). Use either notation when comparing wheels.

Only with a bolt-on wheel adapter from the vehicle pattern (8×180 or the other recorded pattern) to the wheel pattern. Adapters are directional. Confirm thickness, center bore, thread, stud engagement, clearance, and load rating. Hub swaps and redrilling are not equivalent shortcuts.

You need a directed adapter whose source pattern is 8×180 and whose target pattern matches the wheels. 8×180 to another circle is not the same as the reverse unless the catalog lists both directions. Pick the target on this page; thickness is not chosen automatically.

Spacers must match the vehicle bolt pattern (8×180 or 8×165.1). Choose thickness for clearance and offset. Matching the pattern is not a claim that a given spacer fits the vehicle.

Only when the wheel center bore is larger than the vehicle hub. Catalog records show 124.1 mm. Rings fill that gap. They do not fix every vibration issue and they do not change bolt pattern.

The ring is wheel center bore (outer) to vehicle hub (inner). Enter the bore stamped on the wheel. Catalog matches are exact outer and inner millimetres, not nearby sizes.

No. A hub ring only fills a wheel bore that is larger than the hub. A smaller wheel bore cannot be opened with a ring.

Match the recorded thread. Catalog records show M14 x 1.5. Fastener type: lug nuts. Seat style and length are not in this catalog — confirm those on the wheel before ordering.

Thread must match, but aftermarket wheels often need a different seat style or length. Matching thread is not enough by itself. Catalog records show M14 x 1.5.
