Dial in your own ride control with the KYB AGX Suspension Shock Absorber 743021, a manually adjustable rear shock that drops in as a direct-fit replacement for the 1994-2004 Ford Mustang. The AGX lets you design your own damping performance without special tools, quickly and as often as you want — one simple adjustment increases both rebound and compression damping, so you can tune each corner up to 125% above the vehicle's OEM design.
Adjustable damping: Depending on application, the AGX uses either an eight-position knob or a four-position screwdriver slot; both offer the same overall capability and adjust externally without lifting the vehicle or removing the tires.
Velocity-sensitive valving: Precision multi-stage hydraulic valves react instantly to driving conditions to help maintain tire contact and vehicle control across a broad performance range, on the street or the track.
Durable build: A seamless working cylinder is matched with a Teflon-coated piston band for a positive seal and longer life.
Safety-system ready: Engineered to help vehicles equipped with electronic safety systems such as ESC and ABS.
This is a rear shock built for more demanding conditions than OE-replacement parts handle. Sold individually; order the quantity your build requires.
