4.5" 2020-2024 Jeep Gladiator JT 4WD Alpine Hybrid Coilover Suspension System by Teraflex

The Alpine RT Hybrid Coilover Suspension System is tailored specifically for the JT Gladiator, accommodating the 3.0L Diesel and 3.6L Gas engines. Each TeraFlex Suspension System has been designed to cater to the subtle differences among the available motor choices within the Rubicon Gladiator lineup.

Falcon Shock-equipped front coilover suspension systems are compatible with JT factory-width axles and the Tera60 or other axles featuring a 3.25" axle tube diameter. These Falcon Coilover Shocks have been developed to meet the distinct demands of the JT Gladiator. While performance is always a priority, no one wants to endure the annoyance of a squeaking, popping, or creaking suspension on a brand-new Jeep. This Hybrid system addresses the common shortcomings of coilover shocks prevalent in today's noisy and generically tuned coilover market. These noises are so common in traditional coilover shocks that they've been given names! These include "Spring Twang," which occurs when springs are compressed and suddenly shift on the coil divider/sliders; "Zipping," referring to the slider noisily moving up and down a threaded shock body; and "Slider Slap," which happens when the slider hits the crossover rings and the heavier spring engages. Additionally, there's the constant "clicking and clacking" of an internal bypass shock and the familiar shock mount bushing "Squeak." It's not the kind of symphony you want to hear.

Falcon coilover shocks, in contrast, are engineered for utterly silent operation. Sealed Gimble Bearing shock mounts ensure solid and noiseless control when combined with the TeraFlex coilover mount solution. This unique mount design allows for full suspension cycling without any component contact. The sleek, hard-anodized shock body, featured on all Falcon Shocks, is the perfect bearing surface for the new sealed and lubricated spring sliders. These sliders also boast roller-bearing spring seats, guaranteeing noiseless spring movement during compression and extension, even during spring twisting.
