These were an item requested by many people that were bending the stock links from hard offroad use. These are sold as a pair and are made of 4130 cromoly and use 3/4" telflon lined 3-pc rod ends and stainless adapter/spacers for years of quiet trouble-free use. What these do is allow for much freer rear suspension movement as there is a huge amount of binding by the stock links (bushings) as well as preventing deflection under hard cornering and braking. Also, there is very little adjustment from the factor cam bolts...so if you back into something, the weak stock link will bend and you are stuck with not nearly enough adjustment to get your tire even close to aligned and it will have massive toe-out. These links offer are super resilient but also offer a ton of adjustment so if you do bend one, just adjust the threaded rod end until the tire is in check and drive on. They look good too. The l;inks shown are red, but they will ship coated black.
