High articulation without the “soft/squishy” feel under load.
Coil bow correction via the included lower front correction pads—quick geometry improvement at the factory spring seat.
Motor-specific upper isolators—matched to the engine configuration specified for the kit.

“Virtual bucket” – more stable coil seating
The concept lowers the effective bucket point to help reduce instability and bowing.

Model/engine-specific isolators intended for MetalCloak True Dual Rate coils.
Lower front coil bow correction pads
Installs at the factory location to help straighten coil alignment and replace worn OEM pieces.

Who it’s for / use cases
For JL/JT builds that want articulation without giving up everyday stability.
For vehicles that see both road miles and off-road trails—predictable handling and consistent ride height matter.
For owners looking to reduce coil bow and improve front spring alignment.
Install notes
Install difficulty: easy.
