Sway Bar Bushing Type A 17mm Greasable

The Sway Bar Bushing Type A 17mm Greasable from PROTHANE is a front and rear suspension component engineered to replace worn factory bushings that deteriorate from road salt, UV exposure, and constant articulation. As a mechanic, you'll recognize that sway bar bushings are critical to chassis stiffness and cornering response—when they wear, you lose lateral stability and develop clunking noises from the suspension. This greasable polyurethane bushing pair restores factory geometry while offering superior longevity compared to OEM rubber, making it ideal for daily drivers seeking improved handling without a full suspension overhaul.

Constructed from high-durometer polyurethane with steel brackets and cadmium-plated hardware, the 17mm bushing accommodates standard sway bars across most domestic and import vehicles. The greasable design allows periodic maintenance via zerk fittings, extending bushing life by reducing friction and preventing premature cracking—a feature absent in sealed alternatives. Polyurethane resists oil contamination, ozone degradation, and temperature extremes far better than rubber, while the red color serves as a visual quality marker in the aftermarket suspension world. The compact dimensions (3.25 x 2.7 x 3.8 inches) and lightweight construction (0.58 lbs per pair) ensure straightforward bolt-on installation without frame modifications.

Suspension specialists and DIY enthusiasts benefit most from this universal fitment, as the 17mm bore accommodates the vast majority of OEM sway bars without requiring adapter brackets. Installation is accessible to intermediate mechanics—disconnect the sway bar end links, unbolt the bracket assembly, press out old bushings, and install the new polyurethane pair with fresh grease applied to zerk fittings. These bushings are compatible with factory suspension geometry and work seamlessly with lowering springs, coilovers, or stock setups. For owners experiencing wandering highway feel, excessive body roll, or suspension noise at turns, this upgrade delivers measurable improvements in response and eliminates the slop that develops in worn OEM bushings.
