To install the fifth generation (C5) Z06 wheels on your Chevy C1500 you simply need some spacer adapters to counter the wheel's offset and get from the factory truck 5 x 5" to 5 x 4 3/4" bolt pattern.

Here's the spec. I wrote for mine and provided to parts supplier.

Installing 2001 Corvette Z06 Wheels on a 1991 Chevy C1500 SS454:
• Spacer Depth = 1 1/4" (31.75)
• Vehicle Hub Flange = M14-1.5 x 5 x 5 (127)
• Wheel = M12-1.5 x 5 x 4 3/4 (120.7)
• Lug = Truck has a M14-1.5 lug size and the wheels have a M12-1.5 lug size

I actually found mine on eBay for around $125 for the set of four.

Note, however, that if you slam your truck as low as I did then the front end takes some lower A-Arm work to clear the inside lip on the wheel. You’ll either have to go with a narrower wheel, different offset (can be counted somewhat with the adapter thickness) or modifications to the lower A-Arm (trimming or replacing with tubular.

 

Awesome look! I really like those wheels.

 

Nice, those look great.

 

Those look really nice, especially with the trucks stance and color

 

Looks amazing. Beautiful truck

 

You didn't say what size the wheels are......

 

C5Z wheels were 17x9.5 and 18x10.5 from the factory..

 

I like the look!! Nice truck

 

My 02 had 19s on the back and smaller on the front. I think they were 18 but I forget.
Chrome factory though.

 

No. Not from the factory.

1) All C5 Z06 wheels were the sizes mentioned above.
2) Chrome was not a factory option on the Z06 wheels. Any chrome plating of factory wheels was done at great cost after delivery.

You had aftermarket wheels.
