what is the bolt pattern for a 1987 Chevy silverado
no i don't think so must hummers have an 8 lug bolt pattern. Chevy 1500 has a 6 lug bolt pattern
1989 2500 6 lug 4x4 silverado chevy, whats the bolt pattern?
the bolt pattern is 8 on 6.5"
The bolt pattern on the 6 lug Silverado is 6-5.5 (6-139.7).
8x6.5
6x5.5
5/5
It is 8 x180
Im not sure it all depends on the bolt pattern. The bolt pattern depends on what axle the truck has and stuff like that. I doubt the bolt pattern is the same.
6x5.5 or 6x139
Bolt pattern? On what? The cylinder head, wheels, transmission, where are you asking about? Unless you need to know the dimensions and location of every bolt on the vehicle, in which case you're out of luck. Nobody knows that except Chevy, and for a 1999 vehicle you'd be hard pushed to get that information.
