End Links made by Energy Suspension replace the original soft rubber grommets with hyper-flex polyurethane which can reduce body roll and increase traction during a turn. Energy Suspension’s sway bar end links can tighten up the cornering ability of the track car or can be a replacement for the daily driver's use. The sway bar is more effective when it is most stable, so replacing soft or worn rubber end link bushings can have an impressive effect on how the vehicle handles while cornering. The difference can be known if turns are taken at speed or if the grommets of the end links have been damaged due to time or the elements.
