Why Your Rubber Bushings Just Aren't Cutting It

Rubber < Aluminum
There's Nothing Necessarily Wrong With Honda's Rubber Suspension Bushings but, like most rubber parts that are constantly squished, stretched, and twisted, they wear out. But even when new, most OEM bushings are designed to be a bit forgiving, making compromises in terms of handling and performance all for the sake of comfort and ride quality. Not everyone is willing to make those compromises though, which is where aluminum spherical bearings come into play. Aluminum spherical bearings are much more rigid than rubber or even polyurethane-they are, after all, made of metal, not exactly something soft. Their non-compliance nature allows for more precise and predictable handling, helping keep the tires firmly planted, despite the conditions. Many Honda rear trailing arm assemblies are among the best places to reap the benefits of aluminum spherical bearings. Rigid rear trailing arm bearing assemblies, like those offered by Procar Innovations, allow for less rear suspension squat under acceleration, which helps keep the front tires planted, improving traction. Solid rear trailing arm bushings also help keep the trailing arm from veering rearward under braking, which means better stopping. Besides, OEM bushings are soft, even weak, and offer far too much compliance under hard cornering, meaning suspension changes, like toe, can occur at times you'd rather it didn't. It's a classic example of suspension geometry not working in your favor. Fortunately, replacing the mushy, factory-issued pieces with aluminum spherical ones is relatively quick, easy, and requires just a few tools.
