The previous owner lowered the truck. I think it was a 3" lowering lief spring kit he put on front and back. And the tires and wheels lowered it about another 1 1/2"
The longer studs were needed because of the
LIERS, CROOKS, and THIEVES at Stockton wheel.
Those are new wheels that were supposed to be custom back spaced to clear the brake kit. Well after waiting months and months for the wheels…. they didn’t clear the caliper. The only way I could use them is to use 1/4 inch spacers. Needed longer studs and had to go to a larger diameter. It was a total nightmare dealing with them. They refused to make the order right and straight up lied.
I ordered the longer studs from my local CARQUEST auto parts. I don’t recall the brand. I took the old stud with me so they could match the shoulder diameter and length.
the red wheels and black wheels are 15"
this thread talks about extended lug nuts. May work for you
Good luck
