They make a vehicle’s sway bar system much more effective like adding a larger, higher performance sway bar! Made of Hyper-Flex(TM) polyurethane that lasts much longer than O.E.M. rubber bushings. Fwd 1-1/8in.
Only black Energy poly has graphite mixed in so that it self-lubricates if it ever begins to wear. But it doesn't wear if you apply the included silicone grease. I use black Energy poly for every available application on all my trucks, and they all ride smoothly. Some of the bushings have been on my trucks for over 400,000 miles and are still as tight as the day I installed them. I've even removed some from worn or broken parts and re-installed them on the replacement parts because there's nothing wrong with the bushing. Other brands & colors do not have graphite and aren't worth buying.
