Our Thru Tube Link Mount allows for a full weld around tube for ultimate strength that you want for your links. With the forces applied to your links your gonna want something with some heft. Made from .250" steel these mounts aren't lacking the least amount of beef. Application is meant for 1.75" OD tubing (we suggest .250" wall) and bolt hole comes as .500" so it can be drilled to you liking, up to 1" bolt without sacrificing strength. Sold one pair, for one side.
