X-flex Control Arms | Front | Lower | Jeep Grand Cherokee Wj 2wd/4wd (99-04)

Built for Jeep Grand Cherokee owners who demand maximum articulation and durability off-road, the X-Flex Control Arms deliver the joint strength and pivot range you need for serious trail performance. These lower control arms feature fully greasable ball-in joints that let you service them in the field — a critical advantage for remote exploration.

Installed and serviced at Road Runner Wheels & Tires. Most suspension upgrades go in the same day. Call (678) 400-6467 to schedule.

What makes these arms different

• Fully greasable joints — service your suspension in the field without removing arms from the vehicle.
• Massive 2.5 inch diameter body — built to handle extreme off-road loads and impacts.
• 1.25 inch threads — heavy-duty fastener spec that matches the strength of the joint.
• 35-degree pivot range on lower joints — nearly double the articulation of stock arms, opening up steeper descents and technical rock crawls.
• 20-degree pivot range on upper joints — preserves suspension geometry while maximizing flex.
