Compatibility Jeep Wrangler JL 392 (2018+) Lift height 2.5″ (front) Coating Black Powder Coat Installation (according to manufacturer) Easy – 1-2 hrs. – No body modifications Key benefits – Two measurable spring ranges (True Dual Rate) – Better control and comfort than typical solid springs – Long “free length” helps keep the spring in the cup even when fully lifted – On-road and off-road stability and predictable suspension performance under heavier loads.
– Constant height after lift and resistance to “settling” over time – Complete with all spring pads/insulators, including lower corrective pads to limit “coil bow” – How True Dual Rate works – spring operation in different ranges Two distinct ranges of spring operation help combine comfort with control and articulation. “Virtual bucket” – More stable spring action The concept of lowering the “fulcrum” improves stability and reduces the tendency to buckle.
What’s included – (2) Front True Dual Rate Coils – (2) Upper Spring Isolators – Thermoset Elastomer (model-specific) – (2) Front Lower Coil Isolator/Correction Pads Kit Contents In the kit, you get the springs and all the necessary pads/isolators for installation.
