Bora, Supreme Suspension to name a couple I know have good quality wheel spacers. Make sure you get a set that are hub centric… if you have after market wheels (which most do) make sure to buy hub centric and rings to keep your wheel centre. I ran 2” Supreme suspension hub centric wheel spacers on my truck (37s) with the hub centric gorilla rings. No issues, bought new offset rims and threw the spacers in my shed on the shelf.
I would recommend only Bora. They are the gold standard. My 1.5” spacers are both hub and wheel centric to my MotoMetal wheels. I cannot confirm that will be the case with Supreme Suspensions…You would need to call them.
Supreme suspension wheel spacers:
These wheel spacers are built to last a lifetime. They are CNC machined out of solid blocks of T6 aircraft billet. And on top of that, they receive a special anodized coating. The premium material that these spacers are made out of are able to withstand even the most extreme environments.
Bora Wheel spacers:
They are made from only the best American made Alcoa 6061t6 billet aluminum and finished with a Black Anodization which is designed to improve aluminum strength and avoid corrosion.
Pretty much the same…
I have personal experience with Supreme Suspension spacers and a few buddies running Bora, both good choices over any other.
