Fits: 2001-2016+ GM 2500/3500 HDFactory tie rod assemblies bend and break. They are simply too small and weak to get the job done, especially in high-stress situations. While they are generally strong enough for stock performance, street driven pick-ups, with the added stress that come from larger tires, racing, and off-road use, won't hold up for long.When compared to factory components:30% larger toe adjusting shaft53% larger tie rod body35% larger outer ball joint28% larger, adjustable inner ball jointNOTE: This product CAN NOT ship to California due to CARB regulations.The fix for these weak tie rod assemblies comes in three stages. All three are bolt-on parts and require no extra modifications to factory components. A two or four wheel alignment is recommended post install.The best we’ve got; these tie rods are overkill for most, for sure, but when it comes to steering components, failure is not something that can be stood for.
