Stance Tension Rods are machined from billet aluminum for strenghth than anodized for durability. Adjustment pieces are zinc coated steel for uncomprised strength. Mounting hardware is Grade 8. The most important part of aftermarket suspension links are the rod ends. Aurora spherical rod ends are one of the most expensive and high quality rod ends on the market, and for good reason. Aurora ends are used in both military and NASA applications. There is no other rod end that can match the quality, precision and durability of Aurora's rod ends. The Stance links use Aurora's strongest billet 3 piece rod end bearings. Aurora bearings use a sintered steel ball to handle extremely high loads. Rod ends feature special chemical bonded PTFE liners for smooth operation, less noise, and long life. The rod end housings are heat treated and zinc coated for strength and durability. Our rod ends offer a high misalignment angle for extreme performance.
