Missalignment does 2 things necessary to run Rod Ends on a 3 or 4 Link Suspension. The first and most important is allow additional room for the joint to pivot and let your suspension articulate. That comes simply from the shape of the missalignment. The second and less important from the function standpoint but equal from the operational point of view is serve as a spacer and reducer. This allows the use of a smaller bolt than the bore of the Heim. Thats it, pure and simple, so why must you have to buy stainless steel missalignment? I own Ruffstuff Specialties and I found a place to get high quality missalignment in Zink plated steel, it does the same job at 1/4 of the cost so I ask you, do you need stainless steel for $14 a pair or plated steel for $4.50 a pair? Made in the USA! Sold individually. These are for a 2" overall width with the joint and misalign to 34 degrees...
