Let's Go Aero (SHP2040-XL) Keyless Press-on Locking Silent Hitch Pin for 2.5in Hitches

One more question, what is the width of the threaded square that fits inside the hitch? Thanks!

Can I use the 2 1/2” pin while using my 2” adapter?

What is the towing capacity of this pin?

Will this fit my GMC 2014 3500 hitch?
