ICON Adjustable Rear Lower Link Kit for 2018-2023 Jeep Wrangler JL

The ICON Adjustable Rear Lower Link Kit replaces the factory rear lower control arms on 2018–2023 Jeep Wrangler JL models (excluding JL Unlimited Rubicon 392) with CNC-machined 1026 DOM tubular steel arms that add length adjustability, increased articulation, and reduced bushing bind. The kit is compatible with 0–3 inches of rear lift over stock and ships as a complete set with application-specific hardware for direct installation into OEM mounts.

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 It Counts

The link arms are machined from 1026 DOM steel and welded in-house by ICON, a process that produces tighter tolerances and more consistent wall thickness than the stamped and pressed construction of the factory units. For a Wrangler JL driven on technical terrain, that difference translates to arms that resist deformation under lateral and torsional loads that would stress or crack stock links over time.

Adjustability That Solves Real Problems

Arm length is adjustable, letting the installer dial in rear pinion angle after a lift is fitted. Correcting pinion angle reduces driveline vibration and extends U-joint life, two outcomes that matter on a vehicle used regularly off-pavement. The PTFE-lined FK rod ends and multi-durometer maintenance-free bushings allow controlled deflection and maximum articulation without the bind that limits suspension travel in stock form, and neither the rod ends nor the bushings require grease for the life of the part.

Validated Before It Ships

Before release, these arms were run through the ICON 1K test cycle, a real-world off-road validation program, to confirm strength, performance, and durability under the conditions a Wrangler JL owner is likely to encounter. The arms carry a semi-gloss black powder coat finish and are covered under ICON's fabricated-component lifetime warranty.

Specifications

Who This Is For and Isn't

This kit suits 2018–2023 Jeep Wrangler JL owners who have installed or are planning 0–3 inches of rear lift over stock and want to correct rear pinion angle, eliminate bushing bind, and increase suspension articulation over the factory lower links.

This kit does not fit the Jeep Wrangler JL Unlimited Rubicon 392, and it is not compatible with rear lift amounts outside the 0–3 inch range over stock. It is a rear lower link kit only and does not include upper control arms, shocks, springs, or any other suspension components.

Common Questions

Will this kit fit a Jeep Wrangler JL Unlimited Rubicon 392?

No. The ICON Adjustable Rear Lower Link Kit (SKU 22023) is not compatible with the Jeep Wrangler JL Unlimited Rubicon 392. It fits all other 2018–2023 Wrangler JL models running 0–3 inches of rear lift over stock.

How much lift does this kit require?

The ICON rear lower link kit is designed for Wrangler JL builds with 0–3 inches of rear lift over the factory ride height. It installs into the OEM mounting locations and does not require cutting or modification of the factory frame.

Do the bushings or rod ends need periodic greasing?

No. The multi-durometer bushings and PTFE-lined FK rod ends in this kit are maintenance-free and do not require grease for the life of the part, reducing the ongoing maintenance burden compared to many aftermarket link arms.

Does this kit include hardware for installation?

Yes. The ICON Adjustable Rear Lower Link Kit ships with application-specific hardware sized for the Wrangler JL's OEM mounting points. An installation guide is available from ICON; professional installation is recommended for suspension components.
