Jeep JL Wrangler 2.5" True Dual Rate Lift Kit

MetalCloak Jeep JL Wrangler 2.5" True Dual Rate Lift Kit – fitment: Jeep Wrangler JL 2018+ (configuration dependent)

Key benefits

• Comfort and stability thanks to True Dual Rate springs—more controlled feel than basic single-rate setups and better support when loaded.
• More usable articulation—the spring design helps maintain spring engagement during deeper flex for better traction.
• Geometry control and durability—Duroflex joints (with Kevlar reinforcement) provide a wide range of motion while helping reduce harshness compared with rigid-style joints.
• More composed handling—Durotrak-bushed axle centering components help reduce NVH (noise, vibration, harshness) and keep the axle more stable through suspension travel.
• Easy bump-stop tuning—adjustable bump stops let you set usable up-travel to match your tire/wheel setup without constant disassembly.
• Shock-ready options—choose a configuration that matches your plan and budget (stock/no shocks or dedicated MetalCloak shock options).
• Improved spring seating up front—includes corrected lower front spring pads/isolators intended to replace the OE-style piece and help reduce spring bowing.

Who it’s for / use cases

• JL owners who want a 2.5" lift that works well on-road and improves capability for light to moderate off-road use.
• Drivers looking for a complete system (springs + axle control + NVH-conscious joints/bushings), not just spacer-based lift height.
• Builds done in stages—shock-related options help match the kit to your plan and budget.

Installation notes

• Driveshaft: with large suspension travel the factory driveshaft may contact/wear OE components at extreme articulation—an aftermarket driveshaft is recommended.
• JL Diesel: factory wheel backspacing is not recommended / may not work as stated by the manufacturer.
• RockSport Black: 2.5" long-travel shocks require proper wheel backspacing; the kit includes the correct brackets depending on axle type (wide track vs standard).
• True Dual Rate springs: powder coating is not recommended by the manufacturer.
• Alignment: professional alignment is recommended after installation.
• System integrity: the kit is offered as a complete system—swapping/removing individual components is not supported by the manufacturer.
• Partial returns: the manufacturer does not accept returns of “parts of the system” if you later decide you don’t need a component.
