Review on Enhance Performance and Stability: Energy Suspension 8.18104G Master Kit for Toyota Tacoma by Tom Herman

This kit seems to have everything you need to replace stock tires with polyurethane if you like that kind of stuff. All bushings are made of high quality polyurethane. However, do not fit polyurethane control arm bushings to your car because polyurethane bushings do not have enough flexibility for control arm bushings so they squeak like crazy and you end up having to change them about every two years. Don't waste time and money installing polypropylene arm bushings unless you intend to take the front end apart every few years. If your OEM tires are bad, take care of it and buy original tires to replace them and get it right the first time.
