The leafer utilizes the trees from the original front end with some plates to clamp the spring in and then some fabbed up rockers on the bottom. Came out great but definitely a one offer. I'd be glad to show some close ups if that helps you get an idea for making one, and its an f150 spring with some brass spacers and impregnated bushes. Doing it again I would put more zerks on it for easy lubrication but as it is now its easy enough to disabled the moving parts and lube when I change my oil
