Featuring a 4.5-inch mounting length straight bolt design, this universal kit replaces worn or failure-prone OEM end links with high-durometer polyurethane that resists compression set, oil contamination, and UV degradation. This end link set is a complete hardware kit, delivering tighter handling response and more predictable cornering feel compared to soft OEM bushings.\u003c\/p\u003e\n\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePolyurethane bushings resist oil, ozone, and UV far better than OEM rubber\u003c\/li\u003e\n  \u003cli\u003e4.5-inch (114.3mm) mounting length fits a wide range of sway bar and end link applications\u003c\/li\u003e\n  \u003cli\u003eStraight bolt style for simple installation without specialized tools\u003c\/li\u003e\n  \u003cli\u003eComplete kit includes all hardware needed for a full end link replacement\u003c\/li\u003e\n  \u003cli\u003eBlack finish for a clean under-car appearance\u003c\/li\u003e\n  \u003cli\u003eBacked by Prothane's Lifetime Warranty\u003c\/li\u003e\n  \u003cli\u003eFirmer bushing material reduces deflection for more consistent suspension geometry\u003c\/li\u003e\n  \u003cli\u003eUniversal fitment makes this end link set adaptable to custom or modified suspension setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eSpecifications\u003c\/h4\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\n    \u003ctr\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003ePRO19-409-BL\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eProthane\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eMounting Length\u003c\/td\u003e\n\u003ctd\u003e4.5 inches (114.3mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eBolt Style\u003c\/td\u003e\n\u003ctd\u003eStraight\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eBolt Size\u003c\/td\u003e\n\u003ctd\u003e3\/8-16 x 7.5 inch hex cap bolt\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eBushing Material\u003c\/td\u003e\n\u003ctd\u003ePolyurethane\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eBushing Dimensions\u003c\/td\u003e\n\u003ctd\u003e3\/4 x 1.150 OD x 3\/8 ID inch\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eMetal Sleeve Dimensions\u003c\/td\u003e\n\u003ctd\u003e9\/16 x 0.083 x 2.750 inch\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eColor\u003c\/td\u003e\n\u003ctd\u003eBlack\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eFitment Type\u003c\/td\u003e\n\u003ctd\u003eUniversal\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eUPC\u003c\/td\u003e\n\u003ctd\u003eN\/A\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003eProthane Lifetime Warranty\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch4\u003eWhat's Included\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2x Hex cap bolts (3\/8-16 x 7.5 inch)\u003c\/li\u003e\n  \u003cli\u003e8x Polyurethane bushings (3\/4 x 1.150 OD x 3\/8 ID inch)\u003c\/li\u003e\n  \u003cli\u003e2x Metal sleeves (9\/16 x 0.083 x 2.750 inch)\u003c\/li\u003e\n  \u003cli\u003e8x Washers\u003c\/li\u003e\n  \u003cli\u003e2x Lock nuts\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eFrequently Asked Questions\u003c\/h4\u003e\n\u003cstrong\u003eWhat is the mounting length of this end link set?\u003c\/strong\u003e\n\u003cp\u003eThe PRO19-409-BL has a 4.5-inch (114.3mm) mounting length, which is the distance between the center of the upper and lower bolt holes in the installed position.\u003c\/p\u003e\n\n\u003cstrong\u003eIs this end link set a direct replacement for OEM end links?\u003c\/strong\u003e\n\u003cp\u003eThis end link set is a universal kit. It is not a direct drop-in for a specific vehicle. It is designed to replace or upgrade sway bar end links on vehicles where a 4.5-inch mounting length and straight bolt style are appropriate. Always verify your vehicle's existing end link dimensions before ordering.\u003c\/p\u003e\n\n\u003cstrong\u003eWhy choose polyurethane bushings over factory rubber end link bushings?\u003c\/strong\u003e\n\u003cp\u003ePolyurethane is significantly harder than standard rubber, which means less deflection under cornering loads. This translates to more consistent suspension geometry, sharper handling response, and longer service life. Polyurethane also resists oil, ozone, and UV degradation that commonly causes rubber bushings to crack and fail.\u003c\/p\u003e\n\n\u003cstrong\u003eWhat bolt size does this end link set include?\u003c\/strong\u003e\n\u003cp\u003eThe kit includes two 3\/8-16 x 7.5-inch hex cap bolts, along with matching lock nuts and washers for secure installation.\u003c\/p\u003e\n\n\u003cstrong\u003eDoes this end link set require any special tools to install?\u003c\/strong\u003e\n\u003cp\u003eNo specialized tools are required. Basic hand tools including a socket set and torque wrench are sufficient for installation. The straight bolt style simplifies the process compared to ball-joint or pillow-ball end link designs.\u003c\/p\u003e\n\n\u003cstrong\u003eHow do I know if the 4.5-inch mounting length is right for my vehicle?\u003c\/strong\u003e\n\u003cp\u003eMeasure your existing end links from the center of the upper mounting hole to the center of the lower mounting hole with the suspension at ride height. If that measurement is approximately 4.5 inches, this kit is likely a good fit. Consult a suspension specialist if you are unsure.\u003c\/p\u003e\n\n\u003cstrong\u003eAre the bushings greaseable?\u003c\/strong\u003e\n\u003cp\u003eProthane polyurethane bushings are engineered to work dry or with a small application of compatible grease. Applying a thin coat of white lithium grease or Prothane's own Slick Grease to the bushing surfaces during installation reduces noise and extends bushing life.\u003c\/p\u003e\n\n\u003cstrong\u003eWhat warranty does Prothane offer on this end link set?\u003c\/strong\u003e\n\u003cp\u003eProthane backs this end link set with their Lifetime Warranty against manufacturing defects, which is one of the most comprehensive warranties available in the aftermarket suspension category.\u003c\/p\u003e\n\n\u003cstrong\u003eCan this end link set be used on a vehicle with a custom or modified suspension setup?\u003c\/strong\u003e\n\u003cp\u003eYes. Because this is a universal kit, it works well in custom builds, lowered vehicles, or applications where the factory end link length does not match modified suspension geometry. Verify the 4.5-inch mounting length suits your application before installing.\u003c\/p\u003e\n\n\u003ch4\u003eInstallation Instructions\u003c\/h4\u003e\n\u003col\u003e\n  \u003cli\u003eSafely lift and support the vehicle on jack stands.
