MetalCloak JL Wrangler (2-door) / JT Gladiator True Dual Rate Coils – Front (JL 2.5″ / JT 1.5″) True Dual Rate™ are springs designed for the Jeep JL Wrangler (2018+) and JT Gladiator (2019+), with a focus on realistic suspension performance across the full range – from daily driving to hardcore cranking.
In this version, you get a set for the front along with isolating and correcting spring alignment components: motor-specific upper isolators and lower front correction pads (coil bow correction).
Compatibility Jeep JL Wrangler 2018+ / Jeep JT Gladiator 2019+ Front position (pair) Lift height JL 2-door: 2.5″ / JT Gladiator: 1.5″ Product ID 7617* Key benefits – Long free length helps keep the spring in the cups even when the suspension is fully lowered (full droop).
– Stable on-road and off-road behavior: better roll control and more confident handling while maintaining comfort – Repeatable car height and resistance to “sitting down” (sagging) over time – Great articulation without the “soft/squishy” spring feel when loaded.
– “Coil bow” correction thanks to the lower front correction pads – quick improvement of the spring’s working geometry at the factory mounting location – Top isolators matched to the engine version (motor specific) – selected for the indicated configuration How True Dual Rate works – height retention and deflection control Animation shows the transition between the spring’s characteristics depending on the deflection. What’s included – (2) True Dual Rate™ front springs – (2) lower front isolators/correction pads – Upper spring isolators matched to motor version (motor specific) Kit contents Included springs and isolator/correction pads for the front. Specifications / facts – Spring material: high-tensile Chrome Steel – Free Length: 21.5″ – Height when fully compressed (Solid Height): 7.25″ – Spring Coating: Black Powder Coat – Spring Insulator Material: Thermoset Elastomer – Lower Front Correction Pads: Shore 90A polyurethane – Spring Diagram and Dimensions – Front (2-door) Manufacturer’s graphic with key spring parameters. “Virtual cup” – More stable spring guidance The concept of lowering the effective “bucket” is to reduce the risk of unstable operation and buckling. Upper spring isolators (Thermoset Elastomer) The isolators are model-specific and designed for MetalCloak True Dual Rate springs. Lower front correction washers (coil bow correction) Factory-installed component – replaces problematic, worn OEMs and helps straighten spring operation. Insulator location on the spring – preview A helpful manufacturer’s overview graphic of insulator placement. For whom / application – For those building a MetalCloak suspension for JL/JT who want articulation without sacrificing stability on a daily basis. – For cars used off-road and on-road – priority: predictable handling and height retention. – For users who want to reduce the “coil bow” problem and improve spring action at the front. Installation / notes – Difficulty of installation: easy. – Body modifications: none. – Estimated installation time: 1-2 hours. – Recommendation: after suspension installation, perform geometry (toe/axle adjustment) with a specialist. – Manufacturer’s note: springs were designed to work best with Duroflex articulated control arms and 6Pak or RockSport shocks. – Manufacturer’s note: powder coating of springs is not recommended (annealing process may change material properties and affect lift; this may void the warranty).
Summary (for content scan) – Front: True Dual Rate™ for JL 2-door (2.5″) and JT Gladiator (1.5″). – High Tensile Chrome Steel, black powder coating. – Included: springs + lower equalizers + upper isolators matched to the engine. – Purpose: stability on the road, greater range of off-road operation, less “coil bow” problem.
