The PROTHANE 19-406 is a universal sway bar end link kit built to replace tired factory rubber links with a polyurethane setup that holds its shape under load. With a 3.5-inch installed sleeve length, this kit reconnects the sway bar to the suspension and restores the firm feedback that worn rubber bushings give up over miles of service. It's aimed at drivers chasing tighter cornering response and anyone refreshing a sagging stabilizer system. Sold as a complete pair with bushings, sleeves, bolts, nuts, and washers, the kit covers a wide range of vehicle applications and slots into our broader end links lineup.
Polyurethane is the reason this kit outlasts the parts it replaces. Unlike rubber, the firm poly bushings don't soften, compress, or distort, and they shrug off oil, smog, road salt, and most chemicals that break down OEM material. The bores are grooved to hold the supplied super grease, which keeps the links quiet rather than squeaking like cheaper urethane. Each link rides on a steel sleeve finished with a cadmium coating for corrosion resistance, and the whole assembly tightens the connection between the bar and the chassis to make the OEM stabilizer work harder. The 3.5-inch length matches a long list of factory applications, and the kit ships with all the hardware needed to bolt it in. Made in the United States, per manufacturer specifications.
Reach for this kit when steering feels vague, body roll has crept up, or the original rubber links have cracked and started knocking over bumps. Replacing both sides at once keeps the suspension balanced and gives you a baseline before chasing further handling work. It pairs naturally with fresh sway bar bushings if you're doing a full stabilizer refresh, and fits alongside the rest of our suspension and components for a complete front-end rebuild. Verify the 3.5-inch length against your vehicle's original links before ordering, since this is a universal-fit part covering multiple makes and models.
The kit is sold as a complete pair and ships with polyurethane bushings, steel sleeves, bolts, nuts, and washers. Everything needed to replace both sides of a sway bar end link assembly is in the box, along with super grease that the grooved bushing bores are designed to hold.
The sleeve length is 3.5 inches. Because this is a universal-fit part, measure your vehicle's original end links before ordering to confirm the 3.5-inch length matches your application.
Polyurethane doesn't soften, compress, or distort the way rubber does, and it resists oil, smog, road salt, and most chemicals. The firmer material tightens the connection between the sway bar and chassis, sharpening handling feedback while lasting longer than factory rubber.
The bushing bores are grooved to retain the supplied super grease, which keeps the links operating quietly. Greasing the bushings during installation as directed reduces the squeak common to dry polyurethane parts.
The 19-406 is sold as a pair kit, enough hardware to replace the end links on both sides. Replacing both sides at once keeps the front suspension balanced.
