Prothane Suspension Control Arm Bushing Kit

Prothane Suspension Control Arm Bushing Kits: Polyurethane Performance That Lasts

When a control arm bushing wears out, the consequences go beyond a clunk or shimmy — alignment angles drift, handling gets vague, and the whole suspension loses the precision it was designed to deliver. Prothane has been solving exactly this problem since 1991, when the brand launched with a singular focus on polyurethane suspension components made in the USA. Today, their suspension control arm bushing kits represent one of the most well-proven upgrades available for drivers who want durable, performance-oriented replacements for factory rubber.

Why Polyurethane Outperforms Factory Rubber in Control Arm Bushings

As a suspension travels, a rubber control arm bushing is repeatedly stretching and flexing. Over time, the center sleeve begins to sag and suspension alignment is thrown out of alignment — and that sagging continues until the rubber fails completely. Prothane's polyurethane addresses this at the material level. Prothane's polyurethane is a firmer bushing than the O.E. — not only does this increase longevity, but it gives the suspension a boost in handling performance. Meanwhile, polyurethane is impervious to deterioration from the effects of ozone and is inherently far more wear resistant, making it an ideal long-term solution for both front and rear control arm positions.

What Sets Prothane's Control Arm Bushing Kits Apart

Prothane suspension parts incorporate a special urethane formula, precise engineering, and a lifetime guarantee — and unique design methods such as splined bores help guarantee years of squeak-free operation. Each kit is engineered for a specific vehicle application, ensuring the replacement bushing matches the geometry of the original mounting location. Prothane's polyurethane bushings offer the most precise and consistent handling with less deflection and no pre-loading — a key advantage over generic or universal alternatives.

Kits cover both front and rear control arm positions. Polyurethane front control arm bushing kits from Prothane replace the original bushings in the upper and lower control arms, providing stable wheel alignment and improving handling while turning. On vehicles with independent rear suspension or trailing arm designs, Prothane rear kits, like their popular Honda/Acura fitments, eliminate unwanted hop or shudder, ensuring superior handling and precise alignment.

Vehicle coverage is a standout strength of the Prothane lineup. Prothane now offers an extensive line of urethane-based performance products for cars and trucks, all made in the USA — whether it's an Asian or European import or an American car or truck. Coverage includes popular platforms from Jeep, Honda, Acura, Mazda, Jaguar, and many more, spanning decades of model years across over 10,000 part numbers.

Installation-Ready Kits with Lifetime Backing

Prothane even includes their own "Super Grease" with each of their parts that requires lubrication, so you can be sure your suspension parts will last for years to come. Prothane has their own proprietary Super Grease designed to complement their polyurethane bushings — a critical detail, since using the wrong lubricant can accelerate wear and cause squeaking. Many of Prothane's bushings are designed with the DIY'er in mind, so a good number of parts can be installed in your driveway as long as you have the time and proper tools.

Prothane control arm bushing kits are available in both red and black polyurethane. Other than the obvious color difference, there is no performance difference between Prothane's red and black bushings — the choice is purely aesthetic. All kits are backed by Prothane's lifetime guarantee, reflecting the brand's confidence in the durability of their material and construction. For any driver experiencing steering wander, alignment instability, or worn-out factory bushings, a Prothane control arm bushing kit is a direct, long-lasting solution engineered for real-world performance.
