JK 4D 3" S/T3 Lift Kit No Shocks.

The all-inclusive TeraFlex Sport S/T (Street & Trail) Suspensions Systems deliver performance and capability in a dependable and maintenance-free package.

The Sport S/T3 Suspension System is at home on black diamond trails or city streets. The 3” lift Sport S/T3 builds on 2.5” lift Sport S/T2 by adding preset rear upper and rear lower Sport flexarms, progressive SpeedBump bump stops, and more.

Although this kit clears the same size tires as the Sport S/T2, the additional components increase ground clearance without compromising on- and off-road prowess. No alignment is needed thanks to the six preset Sport flexarms, heavy-duty front track bar, and rear track bar bracket, which optimize correct caster and pinion angles for 2.5-3” lift heights.

The Sport S/T3 Suspension System can be installed on Friday, wheeled on Saturday, and driven to church on Sunday!

JK 4D 2.5-3.5" Falcon 3.3 Adjust Shocks

Falcon JK/JKU Series 3.3 Fast Adjust Piggyback Shock Absorbers feature a three-position Fast Adjust Knob to change the damping settings from soft to firm, while the middle setting incorporates an eight-position Micro Adjust Dial for more precise tuning between soft and firm.

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.
