Description of Energy Suspension 3 7104G Tracking Bushing
High quality. Made in United States. Professional products. Hyper-Flex replacement polyurethane components stand up well to contaminants that often destroy rubber and have been engineered to give longer-lasting performance and not compress permanently.
Just what I needed for my '69 C10 . It fits trailing arms as it should. Make sure to use the included lube to prevent the urethane from squeaking in the future.
Pros
Polyurethane Hyper-Flex replacement parts withstand the contaminants that often destroy rubber and are designed to last longer without constant compression
