ICON Vehicle Dynamics 2018-Up Jeep JL Wrangler 2.5" Lift Stage 6 Suspension System

The ICON Vehicle Dynamics Stage 6 Suspension System delivers a 2.5-inch lift and more than 30 percent greater wheel travel (3 inches front, 2 inches rear) for 2018 and newer Jeep Wrangler JL models equipped with the 3.6L V6 Pentastar engine. The complete bolt-on kit includes dual rate coil springs, 2.5 Aluminum Series remote reservoir shocks, tubular steel front link arms, adjustable front and rear track bars, bump stop spacers, sway bar links, and all installation hardware. The system accommodates 35-inch tires on OEM or compatible aftermarket wheels without additional parts.

Shipping: ICON parts ship direct from ICON Vehicle Dynamics, mostly by UPS Ground. Lead times vary by part and some items are built to order, so please allow extra time. We email tracking as soon as your order ships.

Geometry Rebuilt for Real Terrain

Increasing wheel travel by more than 30 percent means the suspension can absorb larger obstacles without transferring the impact to the chassis or the driver. The 3-inch front and 2-inch rear travel gains come from a coordinated set of geometry changes, not just taller springs, so the Wrangler JL stays composed on broken surfaces rather than topping out or bottoming harshly. Fixed front lower links increase caster numbers, which improves straight-line stability and steering return-to-center after a turn.

Components Built to Stay Quiet and Articulate

The front lower links are constructed from thick-wall steel tubing with dual durometer bushings. Softer inner and harder outer durometer materials work together to absorb vibration at low loads while resisting deflection under hard articulation, keeping the drivetrain quiet on pavement and binding-free on the trail. The 2.5 Aluminum Series shocks use one-piece impact-extruded aluminum cylinders, which resist corrosion and maintain a consistent bore finish over the life of the shock. Both shocks are fully serviceable if a rebuild is ever needed.

Tire Fitment Flexibility

The Stage 6 system supports 35x12.50-inch tires with OEM wheels or with ICON Alloys 17x8.5-inch wheels at 4.5-inch backspace / -6mm offset, or 18x9-inch wheels at 4.5-inch backspace / -12mm offset. Owners planning to run 37x12.50-inch tires can add the optional Extended Bump Stop Spacer Kit (PN: 22029), sold separately, to maintain proper bump stop clearance at that tire size.

Features

• 2.5-inch lift height: based on a typical accessorized JL build; may run higher on a stock-weight vehicle
• Dual rate coil springs: front and rear, with a lifetime guarantee against sagging or breakage
• 2.5 Aluminum Series remote reservoir shocks: vehicle-specific valving, impact-extruded aluminum cylinders, fully serviceable
• Tubular steel front link arms: adjustable upper, fixed lower, dual durometer bushings for noise-free articulation
• Adjustable front and rear track bars: included; re-centers the axle after the lift
• ICON 1K validated: tested under rigorous off-road conditions for tune, performance, strength, and durability

Specifications

Who This Is For and Isn't

This system suits 2018 and newer Jeep Wrangler JL owners (two-door or four-door) running the 3.6L V6 Pentastar engine who want a significant suspension upgrade with increased wheel travel, improved on- and off-road ride quality, and the ability to run 35-inch or (with the optional spacer kit) 37-inch tires. Two-door models will sit slightly higher than four-door models but remain level when installed.

This system does not fit Jeep Wrangler JL models equipped with the 3.6L V6 eTorque engine. Running 37-inch tires requires the separately sold Extended Bump Stop Spacer Kit (PN: 22029), which is not included. Lift height may exceed 2.5 inches on vehicles without the added weight of a heavier front bumper, winch, or rear bumper and spare tire.

Common Questions

Does this system fit both two-door and four-door Jeep Wrangler JL models?

The ICON Stage 6 system fits both two-door and four-door 2018-up Jeep Wrangler JL models. Two-door models sit slightly higher than four-door models after installation, but both configurations remain level. The system is not compatible with any Jeep Wrangler JL equipped with the 3.6L V6 eTorque engine, regardless of body style.

What tire size does this suspension system support?

The ICON Stage 6 system supports 35x12.50-inch tires as installed, using OEM wheels or ICON Alloys wheels at the recommended specifications. Owners who want to run 37x12.50-inch tires need to add the separately sold Extended Bump Stop Spacer Kit (PN: 22029) to maintain proper clearance at that tire size.

Is this a complete kit, or are additional parts required?

The Stage 6 system includes dual rate coil springs (front and rear), 2.5 Aluminum Series remote reservoir shocks, tubular steel front upper and lower links, adjustable front and rear track bars, bump stop spacers, sway bar links, and all installation hardware. No additional components are required for a 35-inch tire build. The 37-inch tire configuration requires the separately sold bump stop spacer kit (PN: 22029).

Are the shocks rebuildable?

Yes. The 2.5 Aluminum Series remote reservoir shocks included in this Stage 6 system are fully serviceable, meaning they can be rebuilt rather than replaced when worn. The one-piece impact-extruded aluminum cylinders also resist corrosion and maintain a consistent bore finish over the life of the shock.

Does this kit include a California Proposition 65 warning?

Yes. This product contains chemicals known to the State of California to cause cancer, birth anomalies, or other reproductive harm. This warning applies to California residents under Proposition 65.
