ICON Vehicle Dynamics Jeep Wrangler JL Rear Fixed Upper Link Kit 2018-2023

The ICON Vehicle Dynamics Rear Fixed Upper Link Kit replaces the factory rear upper link arms on 2018–2023 Jeep Wrangler JL models with CNC machined and notched 1026 DOM steel arms, welded in-house, and is compatible with 0–3 inches of rear lift over stock. The kit ships as a pair and weighs 27 lb.

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.

Stronger Construction Where the Stock Arms Fall Short

The factory Wrangler JL rear upper link arms are stamped steel units that compromise both strength and suspension articulation. ICON's arms are built from 1026 DOM (Drawn Over Mandrel) steel, a seamless high-strength tubing, CNC machined and notched to precise tolerances, then welded in-house. That process produces a link arm with meaningfully greater wall consistency and weld quality than the OEM part, which matters when the suspension is cycling hard over rocks or washboard.

Bushing Design That Eliminates Bind and Maintenance

Each arm uses multi-durometer bushings, a compound design that combines different hardness zones in a single bushing, to allow maximum angularity through the suspension's range of motion without the bind that limits the stock rubber bushings. Bind forces the suspension to fight itself at full droop or compression, reducing traction and accelerating wear. The ICON bushings require no grease for their service life, removing a maintenance step that is easy to overlook on a trail-driven vehicle.

Corrosion Resistance and Validated Durability

A dual-stage powder coat finish protects the steel arms against corrosion from mud, water, and road salt. ICON validates fabricated components through its ICON1K extreme off-road testing program before release. Fabricated components in this kit are covered under ICON's lifetime warranty.

Specifications

Who This Is For and Isn't

This kit suits 2018–2023 Jeep Wrangler JL owners running up to 3 inches of rear lift over stock who want to eliminate bushing bind, reduce suspension maintenance, and replace stamped OEM link arms with stronger tubular steel units built for off-road use.

This kit does not fit the Jeep Wrangler JL Unlimited Rubicon 392. It is not compatible with rear lift heights greater than 3 inches over stock.

Common Questions

What Jeep Wrangler models does this kit fit?

The ICON Rear Fixed Upper Link Kit fits 2018–2023 Jeep Wrangler JL models with 0–3 inches of rear lift over stock. It does not fit the Wrangler JL Unlimited Rubicon 392; consult ICON's fitment resources before ordering if your build is near the 3-inch lift limit.

Do the bushings require greasing or periodic maintenance?

The multi-durometer bushings in this upper link kit require no grease for their service life. The design eliminates the maintenance interval associated with standard rubber or polyurethane bushings, which is a practical advantage on vehicles used frequently off-road.

What does "fixed" mean in the context of this upper link kit?

A fixed upper link arm has a set length and does not include adjustment for pinion angle or caster correction. This kit replaces the factory arms with stronger 1026 DOM steel units at the stock geometry; it is not an adjustable or cam-bolt style link.

Is a Prop 65 warning associated with this product?

Yes. California residents should be aware that this product contains chemicals known to the State of California to cause cancer, birth anomalies, or other reproductive harm, per Proposition 65 requirements.
