Fixed-rate Falcon JK/JKU Series 2.1 Monotube Shock Absorbers are engineered to deliver increased stability, improved ride quality, and comfort for daily driven Jeeps in a compact and affordable package.

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.

Falcon shock absorbers and steering stabilizers are engineered to meet the unique requirements of the JK Wrangler/JKU 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, the new corner-specific Falcon Series 3 Piggyback and Falcon Series 2 Monotube 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.


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.

Thanks to Teraflex for getting this product out in perfect time for my 2015 Rubicon project!! I had already installed Teraflex 3"lift and long arm kits; then installed a Gobi rack and a Tepui tent: too much weight for my standard Teraflex shocks. Called and got a recommendation for these new Falcon Shocks... and managed to get in on some of the first shipped out.. what an incredible difference they made! Onroad handling is the best I have ever experienced in the two Jeep builds I have done: I mean, Awesome! Recently had to do a long drive with the addition of an inflatable boat, 9.9 outboard, fuel tanks etc onboard.... was amazed at the amount of sway control these shocks added: and I pushed it hard on a very windy back mountain road w/5mph turns... so much fun! As much as I have enjoyed Teraflex suspensions since 2001, I cannot find any reason to buy or change this set up now: its better than hoped for, dialed in to near perfection... Thanks again Teraflex! You Rock.. and I'm Rolling!!

I installed these on my 2010 4dr JK with a 3in lift already on jeep. They are off the hook. I had pro comp shocks on there before and they hit so hard. These shocks are way softer on the street , they are Exactly what i was looking for in a shock. Now the awesome part about these shocks are the handling. My jeep turns on a dime now they take away all the body roll when you turn sharp.This is the closet you are going to make your Jeep turn like a car. I am so happy with the way my jeep handles now it really is a night and day difference, I also did install the new 2.1 steering stabilizer I could not be more pleased with my purchase.
