They are a universal bushing for any vehicle whose sway bar end links accept this standard size, replacing worn or deteriorated rubber factory bushings.\u003c\/p\u003e\u003cstrong\u003eHow do I know if PRO19-427 fits my vehicle?\u003c\/strong\u003e\u003cp\u003eMeasure the inner diameter (bolt diameter) and outer diameter of your existing end link bushings before purchasing. PRO19-427 fits applications using 1\/2-inch bolt diameter and 1-inch outer bushing diameter. Compare with your factory bushing dimensions to confirm fitment.\u003c\/p\u003e\u003cstrong\u003eHow many end link bushings does a typical vehicle use?\u003c\/strong\u003e\u003cp\u003eMost vehicles use 2 to 4 end link bushings per sway bar (one per end link, two ends per bar). The PRO19-427 set of 8 typically covers both front or rear sway bar end links with bushings to spare depending on the number of positions per link.\u003c\/p\u003e\u003cstrong\u003eAre polyurethane end link bushings noisier than rubber?\u003c\/strong\u003e\u003cp\u003ePolyurethane bushings can produce minor squeaking if not lubricated properly during installation. Apply the included or recommended polyurethane grease to all bushing surfaces during installation to minimize noise.\u003c\/p\u003e\u003cstrong\u003eWill PRO19-427 improve handling?\u003c\/strong\u003e\u003cp\u003eReplacing worn rubber end link bushings with Prothane polyurethane eliminates slop and compression-set deformation in the end link assembly, resulting in more immediate sway bar engagement under cornering and improved lateral body control on street and light track use.\u003c\/p\u003e\u003cstrong\u003eDo I need to press in the PRO19-427 bushings?\u003c\/strong\u003e\u003cp\u003eEnd link bushings are typically press-fit or slide-fit depending on the end link design. PRO19-427 bushings are installed by hand with lubrication and do not require a hydraulic press in most applications.\u003c\/p\u003e\u003cstrong\u003eAre PRO19-427 bushings CARB compliant?\u003c\/strong\u003e\u003cp\u003eProthane polyurethane bushings are designed to be smog and emissions neutral and do not affect vehicle emissions output. Consult Prothane directly for CARB compliance status if required for your state.\u003c\/p\u003e\u003cstrong\u003eCan PRO19-427 bushings be used in any climate?\u003c\/strong\u003e\u003cp\u003eYes. Prothane polyurethane is engineered for year-round use including cold-weather climates where rubber bushings tend to crack and harden.
