The 85-88 Series AFCO shocks were specifically developed to bring optimum performance, quality, and tunability to the Modified racing market. The shocks incorporate flow-matched billet aluminum pistons and base valves that were developed in-house using 5-axis CNC machining technology and EMA dyno capability. Each piston and base valve was developed together to minimize hysteresis and utilize premium quality hardware and shims for a balanced response. The steel gas reservoir, or “bulb”, has been weight and size optimized for better fit without increasing pressure gain. The 86 and 88 Series IMCA legal shocks utilize the new IMCA “universal” fill port that can be easily changed to a Schrader valve application when sanctioning rules allow. The shocks are 100% owner-serviceable or can be serviced by any AFCO shock tuning center for convenient and fast turnaround.
