Wheel Spacers on a RK25

[Bert the Bard]

New tractor owner here.
I have a front end loader on the RK25 but I had a couple butt pucker moments on an incline that I didn't feel was very steep at all.
Any RK25/TYM T25 owners have any recommendations for size of wheel spacers, brand, and where to get them?

Bro-Tek has aluminum rear spacers for the RK25 in 2 and 3 inch models.

Bora has steel and aluminum spacers for the front and rear.
