3500hd 4x4 pcd?
« on: October 05, 2017, 03:31:02 PM »

I've got a 1990 3500hd that's been converted to 4x4 with a DNA 70, it's fitted with 10 lug 19.5x6 wheels, I'm thinking about getting some super singles for the front, what is the pcd of these trucks, I'm in the UK so hoping to find some 10 lug wheels off a truck I could use for some more width. Thanks

The pattern is a somewhat unique 7.25" and it's hubcentric, on a 5.25" hub bore, and the wheel studs are 5/8"

I don't think you're going to find any super singles in that pattern as the bolt circle is smaller than just about any other 10 lug pattern out there.  It's a slight variant on one that has been around on "light" heavy duty trucks since the 1940's, maybe even earlier than that.

The original wheels on a factory 3500HD which is 2WD are 6" wide.  Rickson Wheel offers some steel 19.5" wheels in the correct pattern in 6.75" and 7.5" widths, if that helps.  Not sure how wide you'll be able to go, though, without rubbing sidewall on suspension pieces or the frame.
