Hi-Performance Polyurethane vs. Rubber, You Choose!

Production vehicles are built with Rubber bushings throughout their suspension, chassis, and related systems.  These rubber bushings deteriorate at a very rapid rate and create what people call a “spongy” ride, which leads to prempolyurethane suspension spacersature failure of components.  This leads to costly repairs that could happen to you again in a short amount of time if the root of the problem is not corrected.  Some of the following accelerate the breaking down of factory rubber bushings and create more problems for you: Higher horsepower, oversized tires, Lifted truck, Lowered car, and oil/fluid leakage. The Solution… PROTHANE™, ENERGY SUSPENSION™, and DAYSTAR have all become synonymous with innovative Hi-performance polyurethane, also called “urethane” for short, based bushings and driveline component.  A Polyurethane component for your suspension is what corrects the feel of your vehicle and protects your vehicles components from premature failure. From bushings, bump stops and body mounts to stressed driveline components like motor mounts, transmission mounts, and lift kits, these major manufacturers are constantly developing innovative new hi-performance polyurethane based parts to fit your needs. As enthusiasts and racers ourselves we take great pride in offering you the best in Hi-performance polyurethane components for your suspension, driveline, and chassis to enhance the performance of your vehicle.  Coming soon - we will be carrying PowerFlex and SuperPro bushings.

Polyurethane is an ideal material for Performance Suspension Bushings, motor and transmission mounts. Don't get us wrong, rubber suspension bushings and mounts are a proven compromise. However, if you are taking frequent trips to the track or trail, or just an enthusiast looking for a nicer ride on the street, you need to have Polyurethane suspension and driveline components giving you the control you want and need.  Polyurethane bushings are firm enough to control movement and maintain alignment in sway bars, control arms, and other stressed suspension components without the harshness or resonance associated with solid metal suspension bushings. We believe that after experiencing the precise steering, road feedback, and the added firmness polyurethane bushings offer, you'll never go back to rubber bushings. If you have additional horsepower, plus size tires, lifted truck suspension, or lowered canyon carving street setups, all mixed with normal atmospheric conditions and undercar grit and grime, can and will stress rubber bushings beyond their design limits.
