These StrongArms rear upper are a direct replacement for the stock trailing arms compatible with 1965-1966 Chevy Impala.
They utilize R-Joint Technology and add strength to help get power to the pavement.
R-Joints are a revolutionary rod end design that provides low friction, full range articulation, long service life, lateral stability, and quiet operation.
Articulates in 3 planes with 360-degree axial rotation and 30 degrees of total lateral rotation.
Polished stainless ball and RTX10 composite cage provide consistent low friction movement.
Special RTX10 composite cage requires NO lubrication.
Self-cleaning design…movement is not affected by ANY water, grit, dirt, or debris.
Spring-loaded closure keeps the mechanism tight and rattle-free for LIFE!
