i just picked up some fox 2.5's and they have spacers in the ends which reduce the mounting bolt to 1/2". i pulled the spacers out and measured the hole. its 5/8. i can make some spacers to the same lengths to allow the shock to move like these spacers do, but allow me to run a 5/8" bolt, or even drill these spacers out to run a 9/16" bolt. should i bother or will a 1/2" bolt be enough to hold up my 7000# truck?
