Falcon SP2 3.1 Piggyback performance shocks by TeraFlex deliver increased stability, improved ride quality, and comfort on road, while the increased compression damping provides more aggressive off-road handling

Falcon shocks have optimized tuning for on- and off-road driving, and are ideal for daily driven Jeeps as well as the serious enthusiast wanting a consistent, controlled feel through all driving conditions. The4se shocks have been designed specifically for the JL EcoDiesel/4xe/392.

The front lower offset eyelet design provides maximum shock body to frame clearance during articulation, while the rear Roost Guards prevent shock shaft damage from rocks kicked up by the tires.

EcoDiesel/4xe*/392 front shocks feature a modified reservoir body for proper fitment. Rear shocks clear DEF tank and exhaust system while maintaining maximum travel Piggyback.

The Piggyback design increases oil and gas capacity for reduced heat, which allows top notch performance throughout the entire trail. Moving the gas charge into the reservoir allows maximum amount travel, and Flows 6x more oil than restrictive reservoir hose designs. This feature eliminates common leakage issues found in banjo and swivel fittings. Falcon also provides easy hand adjustable cartridge kits, which are available separately — contact customer service for details.
