Rancho RockGEAR High-Steer Knuckles are made from high-strength steel for maximum endurance. These knuckles are designed to align the geometry of the track bar and drag link in order to decrease bump steer. This adds durability to the weakest points within the steering envelope when off-road driving. Rancho RockGEAR High-Steer Knuckles fit both left- and right-hand drive models. But please, keep in mind that in order to use the High-Steer Knuckles, you will also need 3-in. track bar mount and a flip drag link that are sold separately.
