Total Control leaf-spring, polyurethanebushing sets provide a more stable interface between the leaf springs and the chassis. Poly material has a significantly higher durometer making it more difficult to compress, resulting in reduced deflection and better handling. Front set includes black poly bushings for leaf spring front eyes with sleeves, and hardware. Rear shackle set contains black poly bushings for leaf spring rear eye and chassis mounts, heavy duty shackle set and Grade 8 hardware. Multiple tubes of Teflon® impregnated assembly lube are also included with each set. Each set will fit 1964-1/2 to 1973 Mustangs and many other ‘60s and ‘70s classic Fords.
