Sealed ends keep grease in the bushing eliminating excessive wear and contamination. When used together, the grooved pin and sealed bushing assemblies will provide up to three times the life compared to the OE spring pins and bushings. This combination offers; easier greasing and ease of installation when used with our unique install tools.
