18-Up Wrangler JL 4 Door Alpine RT Coilover Suspension System – 60/60 – 2.0 eTorque TeraFlex

The Alpine RT Coilover Suspension System is designed specifically for the JL Rubicon Wrangler, as well as for each of the Rubicon’s powertrain options.

For every Rubicon Wrangler powertrain, a corresponding TeraFlex Suspension System has been meticulously crafted to accommodate the subtle differences among the available motor choices within the Rubicon Wrangler lineup.

Our Falcon Shock equipped coilover suspension systems cater to JL Rubicon factory width axles, as well as the Tera60 or other axles featuring a 3.25 inch axle tube diameter.

These Falcon Coil Over

Shocks have been developed to meet the distinct demands of the JL Wrangler. While performance is always a priority, who wants to endure the annoyance of a squeaking, popping, or creaking suspension on a brand-new Jeep?

This system has been engineered to address 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, which refers 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 ever-familiar shock mount bushing Squeak. Clearly, not the kind of symphony you want to hear.

Falcon coilover shocks, in contrast, are meticulously designed 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, serves as 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.
