3.5" 2020-2024 Jeep Gladiator JT 4WD Alpine RT3 Short Arm Extended Travel Suspension System by Teraflex

The Teraflex 2033000 Alpine RT3 (Rogue Trail) 3.5-inch Extended-Travel Suspension System for the Jeep Gladiator provides an unprecedented smooth and quiet ride for excellent performance on and off the road. This is among Teraflex's most sought-after and adaptable systems; the 3.5" suspension is a favorite among enthusiasts, allowing for 35-inch to 37-inch diameter tires (depending on fenders used).

The Adjustable Alpine IR Short Arms are pivotal in balancing front caster angle pinion angles and optimizing rear pinion angles, anti-squat geometry, and tire position. Complemented by heavy-duty forged adjustable front and rear track bars, this system enhances steering response, centers the axles for optimal vehicle roll center, and minimizes body roll, delivering unparalleled handling.  The result is an improved suspension geometry, relaxed control arm angles, and superior ride quality across diverse terrains. These systems restore front and rear roll axis angles, minimizing brake dive and acceleration squat. TeraFlex suspension systems are engineered to reduce noise, vibration, and harshness, providing a refined driving experience.

Teraflex coil springs are engineered and tuned to provide the best combination of ride quality and off-road performance. The springs are dual-rate for optimal performance in all terrains. Rear Forged ST Sway Bar, and Extended-Travel Shock Accessory Kit safely provide 16” of rear suspension travel.

Alpine IR Bushings

The Alpine IR Control Arms boast Independent Rotation (IR) Bushings, a revolutionary feature that eliminates bushing binds during full suspension travel. This innovation reduces the overall bushing load during articulation, ensuring unrestricted droop and delivering a noticeable improvement in ride quality, whether navigating highways or trails.

Short Arm vs Long Arm Kit?

When purchasing a Jeep lift kit, a common option is to choose between a "short arm" and a "long arm" kit. For those new to Jeeping, this refers to the control arms and their length. A short arm kit uses the factory mounting points for the control arms.  The long arm kit uses control arms that are extended in length over factory arms and require the installation of new mounting brackets. This design allows for greater suspension travel and articulation, resulting in improved off-road performance, especially in challenging terrain. The downside to the long arm kits is installation is more difficult, and the cost is usually significantly higher. The Short Arm kits are great for those who do not need the most extreme suspension articulation when off-roading, and installation is much simpler (use the factory mounts).

Shock Options

At Jack-it we offer the Teraflex lift kits in various shock packages to fit different budgets and needs.

Bilstein 5100: This German-engineered shock is a great option for those looking for great on- and off-road performance without breaking the bank. It is a mono-tube gas shock with a zinc plate finish and 46mm piston.

Falcon SP2 2.1: The 2.1 Falcon shock is an excellent mid-range shock with a large 2.3-inch body and a massive 7/8-inch piston. During installation, they can be set to "Soft" or "Performance" mode to best suit your driving preferences.

Falcon 3.3 Fast Adjust: Our most premium option is the Falcon 3.3 Fast Adjust shock. These awesome shocks feature a reservoir for added oil capacity and the Fast Adjust knob to alter dampening characteristics based on the current terrain quickly. Like the Falcon 2.1, they use a 2.3-inch body and a 7/8-inch piston.
