Shock Rear STR.T 64-70 Ford Mustang

The Shock Rear STR.T 64-70 Ford Mustang from KONI SHOCKS is a purpose-built monotube suspension component engineered for classic Mustang enthusiasts and restoration specialists who demand OEM-equivalent performance with modern damping technology. This rear shock absorber addresses the handling limitations of original 1964–1970 Mustang suspensions, which were designed for highway comfort rather than cornering precision or load control. Whether you're restoring a 289 or 428 Cobra Jet, upgrading a street cruiser, or preparing for weekend track duty, this KONI shock restores balanced weight transfer and eliminates the wallowing and brake dive that plagued first-generation Mustangs.

The STR.T designation identifies KONI's twin-tube hydraulic design, a proven architecture that combines robust fade resistance with repeatable damping across wide temperature and load ranges. The steel construction with orange paint finish ensures corrosion resistance and allows easy identification during installation and future service intervals. At 5.42 pounds per unit and measuring 25.45 inches in overall length, this rear shock fits precisely within the 1964–1970 Mustang's rear suspension geometry, providing 1.3 inches of effective travel per side. The twin-tube internal architecture separates the main piston chamber from a secondary compensator chamber, maintaining consistent damping force even during sustained cornering or emergency braking, where single-tube designs often suffer performance degradation.

Buyers restoring concours-level Mustangs or building restomod platforms benefit most from this shock's transparent performance—it handles spirited driving without introducing harshness on rough roads. Installation requires no frame modifications; the shock bolts directly to original mounting points using factory hardware, making it ideal for bolt-on upgrades that preserve authenticity. Pair this rear unit with matching KONI front shocks for balanced suspension geometry and maximum control. This product is sold individually, so ordering two units covers both rear corners. Compatibility is exclusive to Ford Mustang models 1964–1970, spanning all engine variants and suspension configurations from that production run.
