AFCO Quality, Performance, and Value INSIDE a STEEL BODY! The difference is only skin deep: All internal parts of the AFCO 19 Series Steel Take-A-Part shocks are identical to the components inside of AFCO's aluminum body shocks, so you can expect the highest levels of performance and durability. AFCO 19 Series Steel Body Take-A-Part Shocks let you meet your "steel shock rule" and still allow you to run the most precise shock in the industry. With the Take-A-Part, you are no longer limited to "off the shelf valves, " and you can have the performance of your used shocks brought back to full factory spec with a rebuild rather than having to purchase a new shock.
