Are they a bolt on deal for our trucks? anyone know or done it?

 

I know with the H2 wheels guys run you have to machine the center bore to clear the hubs. I would think any other GM wheel would require the same.

 

Machining the bore will make a safer wheel than having too large a bore though. On the stock wheel the weight is carried and the wheel centered at the bore/register face, and the lugs only hold the wheel tight to the hub and transmit power.

 

i put H2's on my first gen and I had to buy 1.5 in adapters and bore the centers out.

 

These are off of an '08 I was told. Machine out the center and away you go. I think they look better on a dually front axle...

 

anyone know what size the lugs are? are they 1/2" like our trucks or are they bigger like 9/16" or 5/8"?
