20mm wheel spacers, 7/16 thread: help me find?

[brrian]

I'm having no luck finding 20mm (or 3/4") hub-centric wheel spacers, 4.75" bolt pattern both ways, with 7/16 threads. I can find 12x1.5mm threads, or can find 7/16" in a 1" spacer, which is a bit too thick. Anybody know of a place I can get this exact combination?

If I can't find this I'll go with 12x1.5mm threads but for OCD reasons I guess, I'd like to keep everything 7/16".

Thanks...

Just spitballing here, but could you purchase the 1" variants and machine away material from the backside? It wouldn't negatively affect anything I can think of so long as it's milled true. Then you don't have to compromise.

2 possible reason you can not buy.

The ones in the pic from 81cutlass, let's call them adaptors, bolt to your car before the wheel. That can not be so thin that the nut sticks out. Must be thicker than nut.

A spacer changes the load further away from the base. Maybe in this case too far. These are typically pretty thin.

Check these guys out, in Reno area.

I bought a set of Bora 1.5” spacers for my 2017 Ram 1500 4x4 and they’ve been on the truck for 80,000+ miles without issue.

Just had them build a 1” set for my son’s ‘86 El Camino, probably should have tried 3/4” for a PERFECT fit.

They will custom build them for you, billet materials and in my experience have held up wonderfully.

The way I went about installing them was to bolt them on and torque to specs and then loosen and redo 3 times. Then final instal and I did the same with the wheel to the spacer.

Both on my truck and my son’s G-Body I removed the wheels after 5 miles to check torque and again at 200 miles and again at 1,000 miles. Each time the torque was spot on.

Some folks vehemently despise adapters/spacers, but it probably comes down to your use and quality of the part.

The Bora and Motorsport-Tech pieces are not cheap, and quite a bit more than you’ll find on Amazon and E-Bay, but again, safety and quality. Not to mention they will build them to your specific needs.
