    Series 2.1 Monotube: Falcon Series 2.1 Monotube Shock Absorbers deliver increased stability, improved ride quality, and comfort for daily driven Jeeps in a compact and affordable package. Fixed-rate Series 2.1 shocks have been optimized for on- and off-road driving. Volume Optimized Damping: Traditional velocity sensitive shock absorbers react quickly during low speed driving causing excessive “head toss” on rough terrain – or even driveways. Conventional damping then firms up during faster speeds resulting in a jarring ride. Falcon’s proprietary Volume Optimized Damping (VOD) features a digressive linear valve that produces quicker ramp up for increased damping volume, which improves vehicle feedback and control during low-speed driving. VOD also improves the shock absorber’s ability to reduce bottoming out at full compression during faster speeds or over uneven terrain. Falcon History: Historically, universal shock absorbers and steering stabilizers have been adapted to fit many applications with minimal tuning. Falcon Shocks rewrites the book on damper development with these new shock absorbers and steering stabilizers that are engineered to meet the unique requirements of the JL Wrangler/JLU Wrangler Unlimited. 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. Built from the ground up with a focus on fitment and function, Falcon’s corner-specific shock absorbers deliver the best damping characteristics possible. After a lengthy and painstaking development process, we have delivered these advanced shocks to the awaiting Jeep market
