For the inner pivots they use durable delrin bushings with grease fittings for easy servicing. To mount the arms to the spindle they include high grade 17-4 stainless steel misalignment spacers and grade 8 hardware. All of the components on their upper control arms are rebuild-able or replaceable to make this product last a lifetime.
