MetalCloak Jeep JL Wrangler 2.5″ True Dual Rate Lift Kit (A2125) – Compatibility: 2018+ JL Wrangler Rubicon
The 2.5″ True Dual Rate Lift Kit is a thoughtful base for lifting your Jeep JL: more ground clearance, longer suspension travel and stable handling without the “float” typical of random spring and shock combinations.
In the package you get the key components of the system (front upper control arms, True Dual Rate springs, track bars with Durotrak bushings, adjustable buffers, stabilizer links and shock mounts), and you select the shocks to suit your driving style. Preview of the kit (base variant) Overview graphic – the composition of the components depends on the chosen shock absorber configuration. Product / IDA2125*Lift height2.5 “SpringsTrue Dual Rate™ (front + rear)BumpersRegulated (front + rear), range 1″-4” without removing springsShock options6Pack / RockSport / Fox / no shocks (depending on configuration)Key benefitsTrue Dual Rate™ – stable ride and predictable car behavior on the road, while longer wheel contact with the ground when articulating.
Duroflex™ with Kevlar additive – a self-centering, high swing-out joint with vibration damping closer to OEM than typical “flex joints”.Durotrak™ in track bars – reduced NVH (noise/vibration/roughness) and more confident handling due to a bushing design that operates freely in the vertical axis.
Adjustable buffers – match suspension travel to tires and ground clearance without tedious modifications and without removing springs.
Flexibility in shock configuration – you choose a solution for daily, touring or heavier terrain.

RockSport 2.0 (Silver) – standoff / shaft / bushing Built-in standoff improves fit and clarity for long stroke work. RockSport 2.0 (Silver) – oversized chrome shaft Rugged off-road performance and stable everyday operation. RockSport 2.0 (Silver) – bushing eyes Reinforced attachment point for long use. RockSport Black (reservoir) – view and key components Shock absorber with external reservoir for long travel and tougher conditions. RockSport Black – built-in standoff mounts Offset mounts help maintain the clarity of operation and OE-like fit. RockSport Black – braided hose Tank to shock connection designed for heavy-duty operation and cooling. Fox – example of shock option Depending on the configuration of the kit, you can choose a different type of shock absorbers. For whom / applicationFor those looking for a 2.5″ lift for the Jeep JL Rubicon with an emphasis on stable handling and predictable suspension performance.
For daily + weekend off-road: the kit builds ground clearance and travel while allowing you to match the shocks to your driving style.
For those who want to start with a solid base and upgrade the suspension with more components in the future.
Installation / NotesBecause of the long suspension travel, factory driveshafts may contact OEM components and wear faster at maximum articulation – aftermarket shaft is recommended.
After installation, geometry/alignment performed by a suspension specialist is recommended.
The manufacturer does not recommend powdercoating True Dual Rate springs.
The kit is offered as a complete system – no replacement/removal of individual components from the set.
Note for Diesel JL: factory (stock) ET/backspacing of wheels will not be appropriate.
Outboard Shock Mount: 2″ spacers may be required with OEM wheels; mounts provided for wheels with 4.5″ or less backspacing (or 2″ spacer equivalent on stock wheels).RockSport Black (Black Shocks): large body 2.5″ long-travel – correct backspacing required; appropriate mounts provided depending on axle type.
