I noticed the other day that the new colorados are 6 lug, I was wondering if anyone knew the bolt pattern on them and if it was the same as the full size trucks.

 

I would bet they are the same.

 

Same chassis as the GMT360 essentially right? If so, then they aren't the same. I dont remember the size offhand, but the rims on my TB are a metric bolt spacing.

 

I would imagine so ... The bolts on the fullsize trucks are metric too. I have yet to find a standard bolt on my truck.

I'm not sure if the TB and Canyon is on the same chasss or not. I know there was a plant built especially for the 355 & 345 trucks to supply the plant with these chassis.

Correction ... I'm assuming Dana it making the 345 series too, but since they are going down the same line as the 355, it would make sense.

Oh .. and another interesting fact .. as far as I can tell by lookng around Isuzu makes the engine for the Colorado/Canyon, H3, and I would assume the TB/Envoy too. Isuzu is owned by GM as well.

The tranny (4l60e) is a GM Powertrain part though.

 

THe bolt patterns are the same, however the Colorado has a bigger hub bore. I found this out when I tried to put my 20"s on my roommates Colorado.

 

I just found out about the trailblazer bolt spacing when i tried to put my 20's from my silverado on my trailblazer. I had to order rims specific to the trailblazer to have them fit.

 

I was told the TB and Canyopns weren't on the same frame today ....
