• 2 FMI billet aluminum rear lower suspension arms
• All hardware
• Patent-pending Ultra-Flex joints with low-profile external grease zerks

On a link-arm rear suspension, the lower arms take the axle's acceleration and braking loads and locate it fore and aft as the suspension cycles. Every one of those loads goes through the joints at each end, so the joint decides how the arm feels, how long it lasts and how much attention it needs.

A conventional uniball is a metal-on-metal wear item. Once it wears it squeaks and clunks, and the fix is a complete new uniball assembly. The Ultra-Flex joint is built around a urethane body that stays lubricated, can be greased on the truck, and is the only part to replace when it eventually wears.

A 17-4 stainless steel center ball in a urethane body, greaseable through an external zerk.

• Durable. The Ultra-Flex design is built to last significantly longer than a conventional uniball joint.
• Quieter. The urethane helps isolate road noise and will not squeak or clunk the way a worn uniball does.
• Resists corrosion and rust. The stainless steel components stay constantly lubricated, which makes the joint a strong choice in humid or wet weather.
• Easy to service. The low-profile external zerk lets you add grease whenever it is needed, with the arm still installed on the truck.
• Rebuildable. When the urethane body wears over time, you replace that body instead of a complete uniball assembly.

Made for the Ford Ranger Raptor, 2024 and newer, with the link-arm rear suspension.

What wears out, and what does it take to fix?
