We won't go through the process step by step in this article because it is a pretty straightforward, bolt-on affair. Instead, we want to point out some of the interesting things about Edelbrock's parts. First is the front sway bar, which is made from 4130 chrome-moly steel. Why chrome-moly, you may be wondering? We asked Stuber the same question. "We use chrome-moly for all our front bars. It doesn't take a set like mild steel does." That makes sense when you think about it: A sway bar is essentially a spring. Think of it as a torsion bar or even an uncoiled coil spring that connects the two lower control arms together. Just like springs can sag and settle over time, a sway bar can get lazy as it travels through the same range of motion year after year. According to Stuber, chrome-moly resists this fatigue much better than steel and maintains its crisp control of body roll over a longer period of time.
