Any spacer over 1” is going to induce coil bind in your rear springs. Without getting technical you’re basically running your truck with reduced suspension travel and zero protection from bump stops in addition to accelerated spring wear/sag.
Somebody feel free to tell me I am wrong, but numerous calls to several well known raptor suspension shops have confirmed my suspicions on how these 2 inch spacers behave.
This is definitely true, to an extent. I guess it wouldn’t be as bad of an issue if you installed other supporting mods to the surrounding suspension and bump system to account for the increase, however, 1” I think doesn’t change everything all that much, but our wives might think otherwise.
If you constantly hold weight in the bed, or tow, that accelerated spring wear is apart of that too, so 1” spacer I don’t think would affect the spring itself all that much.
