4.5" 2018-2025 Jeep Wrangler JL 4WD (4 door) Alpine CT4 Long Arm Suspension System by Teraflex

This Teraflex 1524000 Alpine CT4 4.5 inch Long Arm Suspension Lift Kit for the Jeep Wrangler JL is designed for hardcore off-roading without giving up ride comfort. The Alpine CT4 kit features the Alpine Long Control Arms, Brackets, and an adjustable Alpine IR Front Track Bar and Front and Rear Track Bar Brackets for maximum tunability and flawless performance for years to come. Once installed, you will have clearance to fit up 35-inch to 37-inch tires.

Adjustable Alpine Long Control Arms tune caster angle, anti-squat geometry, and tire position. They retain near-factory orientation to reduce bushing stress during extreme droop and reduce shock load transferred through the control arms. The adjustable Alpine IR Front Track Bar and Front (3.5" +) and Rear Track Bar Brackets improve steering response, optimize vehicle roll center, and reduce body roll for unsurpassed handling. This results in improved suspension geometry and relaxed control arm angles for superior ride quality and performance regardless of terrain. These systems restore front and rear roll axis angles to minimize brake dive and acceleration squat. TeraFlex suspension systems reduce noise, vibration, and harshness. Alpine CT Suspension Systems are engineered for hardcore Jeeping without sacrificing weekday ride comfort!

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 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.

Why Upgrade to a 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 is referring 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. If you are serious about off-roading and if it fits your budget, a long arm kit is a great option.
