No. The mounting surface on the factory wheel has pockets between the lug bolt holes so there was plenty of room for the factory studs to poke through the spacers. They didn't stick very far past the spacers anyways. The brand is Adaptech.Did you have to trim the studs on the hubs?
What brand/where did you buy the spacers?
Installed the 1.5” spacers today. I really like the wider stance.
I have a ReadyLift 2” level kit and 295/70-18 Toyos on stock wheels and did not rub at all. After the spacers, the fronts just barely rubbed the inner mud flap. I removed the mud flap brackets and trimmed the mudflaps and no clearance issues at all now. The photo with the floor jack is no spacer.

Those are probably with $75 “spacer” lifts.I saw some horror stories on GM threads about the trail boss and leveling kits. Multiple posts of ball joint blowouts while driving. Some going 45mph. Be careful. I was going to level as well but its not worth it IMO especially considering there will be no coverage under warranty.
When I decide to lift mine its gonna be a complete 4" suspension lift that replaces trail boss components.
Good priceReceived a full Set of 1.5" Spacers (2 pair) from American Trucks today, made by Supreme Suspension. Planning to install tomorrow. Studs say 10.9 type. Only $280 for a set of four. The Link:

Instructions say there are likely indentions (sic) in the wheel to accommodate the stud ends, and use factory torque values.
I wrapped a rag around the pry bar.Do you need to protect the Threads from the pry bar while tightening? And, Thanks! for the tip.
(I have lots of space to work either inside or just outside my airplane hangar, lots and lots of tools, large floor jack ... )
Is it not recommended to put the Transfer case in 4WD (engine off of course) to keep the hubs from turning?
I just applied the brakes with a piece of lumber so I could torque the front ones.Good price
There are indents in the stock Trail Boss 18in wheels. I torqued to 140ftlbs which is correct from what I’ve read. You’ll need a long pry bar or similar to brace against the ground and put between the front wheel spacer studs to keep the hub from turning when you tighten the lugs.
