These spacers are great for using any heim that has a 3/4" bore and installing in a location that has a bracket width of 2.625" that is commonly found in many stock parts. Using this spacer also enables you to keep your 2.625" brackets if you decide to upgrade to a larger joint in the future, rather than cutting off the brackets and welding on new ones. A much better option than using two sets of spacers which allows for multiple shear points. Made from 303 stainless steel and offered in pairs.
