Falcon SP2 2.1 Monotube Shocks deliver increased stability, improved ride quality, and comfort for daily driven Jeeps in a compact and affordable package. SP2 2.1 Shocks have been optimized for on- and off-road driving. “High-Value Performance” is the driving force behind our vehicle-specific dampers for Jeeps, trucks, and SUVs. These Jeep-specific shock absorbers deliver increased stability, improved ride quality, and comfort for daily driven vehicles as well as race-inspired performance, handling, and stability for off-road rigs.

SP2 Mode Adjust:

• Choose between Soft and Performance modes during install

• Tunes both compression and rebound

• Soft mode allows a partial bypass of the main piston for a softer ride

• During aggressive driving, Soft mode retains performance tuning for optimal handling

• Soft mode recommended for rough terrain/surfaces and cold weather

• Performance mode recommended for max on- and off-road handling, stability, and control

Falcon Jeep Shocks (all):

• Vehicle-specific shock absorbers

• Race-inspired performance for increased vehicle stability

• Improved dynamic roll control and low-speed damping

• Large shaft diameter provides a wide range of adjustment on adjustable shocks

• 1-piece energized Teflon bronze piston wear band

• VOD (Volume Optimized Damping) features a digressive linear piston for quicker ramp-up and increased damping volume

• VOD reduces shock bottoming at full compression or over uneven terrain

• OGS (Oil/Gas Separator) prevents cavitation

• Red Line oil for consistent performance across all temperatures

• Synthetic formula also contains special anti-wear and lubricity agents

• 1,000-hour salt spray corrosion resistance test on all hardware
