Front and rear monotube shock absorber kit for Jeep Wrangler JK 2 doors, year 07-18, ideal for a lift between +7.5 and +9 cm (from 3 to 3.5 inches)Falcon Series 2.1 Monotube Shocks deliver increased stability, improved ride quality and comfort for everyday Jeeps in a compact, affordable package. They have been optimized for on-road and off-road driving.The Falcon shock absorber features Volume Optimized Damping (VOD), to improve feedback, stability and vehicle control during low-speed, high-speed and off-road driving. Thanks to a linear digressive valve, as the piston compresses and rebounds, the oil flow is restricted creating a damping effect. VOD's faster acceleration increases the damping volume during low-speed riding, and reduces the shock's bottom out at full compression during higher speeds or on rough terrain.Technical specifications: 25" (63.5cm) shock body offers optimal performance 3/4" induction hardened chrome stem resists rock damage and corrosion 1,000 hour salt spray corrosion test on all hardware 6061-T6 aluminum alloy shock body resists wear and protects internal components
