Looking for 1/2” longer studs on k1500 can get rears but not fronts to use wheels I have. Anyone have any ideas? Been to Dorman, Jegs, Speedway and few other places.

I've had good luck on summits website and using their filters, on my c10 I went a touch larger on the knurl diameter to get the length I needed.

Don’t have a suggestion where to find them, but another idea….
Could you use extended shank lug nuts instead?
Thats what I did on my C10 when I swapped to rather thick alloy wheels and couldn’t get full thread engagement.

You might check with Moser/Quick Performance/any of the axle manufacturers, they typically have all kinds of options for lugs

Longer studs still have to be used with these, and any lug nut. The stud has to extend into the nut a certain amount or you risk a shear force on the stud. I've seen studs fail due to wrong stud/nut combo.

I am not an expert, but can you use rear studs from a dually and shorten them if needed?

That's sorta true. You're right, there has to be a certain amount of stud inside the lugnut, the general rule of thumb is "enough depth to equal the thickness of the stud". I've used the extended length lug nuts in the past on my C10 with the old torque thrusts, the center was so thick that regular lugnuts wouldn't have enough engagement, and I had no issues.

As long as there's enough clearance to fit in the lug hole and as long as the tapered seat hits before you bottom in the cap of the lug (on closed end lug nuts), there's no shear forces applied to the stud.

Did you guys not see my post above?
I agree, and it’s true for any “structural” bolted connection, you need a full nut worth of engagement, which like Huck said is = or > than the diameter of the fastener.
That is what extended shank lug nuts make possible when the lugs are a bit short for typical full engagement.
I’ve had them on the brown truck for a couple years now with no issues. The last time I used them prior was 30+ years ago and no problem then either.
