2024+ Ranger Raptor - Rear Upper Billet Aluminum Suspension Arms with Ultra-Flex joints

Description

Billet aluminum rear upper suspension arms for the 2024 and newer Ford Ranger Raptor, on our patent-pending Ultra-Flex joints. Each joint uses a 17-4 stainless steel center ball in a urethane body and can be greased through an external zerk with the arm still on the truck.

The rear upper links control axle wrap and hold pinion angle. From the factory they locate the axle through rubber bushings, which deflect under load. A machined billet arm with a defined, greaseable pivot holds the axle where it should be without the noise of a worn metal joint.

What Is In The Kit
  • 2 FMI billet aluminum rear upper arms with all hardware
  • Ultra-Flex joints with a 17-4 stainless steel center ball and urethane body
  • Low-profile external grease zerk on each joint
  • Aluminum ball post for the factory rear travel sensor

Why Billet Upper Arms

Under acceleration and braking the rear axle wants to rotate, and the upper arms are what stop it. Rubber bushings are soft on purpose, so they let the axle move before the arm takes the load.

A one-piece billet arm with an Ultra-Flex joint gives that pivot a defined, consistent motion. The urethane body still damps impact and road noise, and the whole joint can be serviced on the truck.

The Ultra-Flex Joint
  • Durability. The Ultra-Flex joint design lasts significantly longer than a conventional uniball joint.
  • Less noise. The urethane in the joint helps isolate road noise, and it won't squeak or clunk the way a worn uniball does.
  • Corrosion resistant. All stainless steel components stay constantly lubricated, which makes this a good fit for humid or wet climates.
  • Rebuildable. When the urethane body wears over time, you replace that body instead of a complete joint assembly.
  • Easy to service. A low-profile external zerk lets you add grease whenever it's needed with the arm still installed on the truck.

The Ultra-Flex joint is patent pending.

Questions

What is in the box?

Two billet aluminum rear upper arms with all hardware.

How do I service the joints?

Add grease through the external zerk with the arm still on the truck. When the urethane body wears, you replace the body rather than the whole joint.

Will the rear travel sensor still work?

Yes. The upper arms carry an aluminum ball post for the factory sensor.

Will it be noisy?

The urethane in the joint helps isolate road noise, and it won't squeak or clunk like a worn uniball.

Does it fit a 2025 or newer Ranger Raptor?

Yes. It is made for the 2024 and newer Ranger Raptor with the link arm rear suspension.

ANODIZED CARE & DISCLAIMER:   read before ordering
⚠️ WARNING:
 Improper cleaning can permanently damage the anodic coating on billet aluminum parts, causing fading, staining, or discoloration. 

SOAPS / CLEANERS THAT DAMAGE :
High-pH (alkaline) soaps, degreasers, and acidic wheel cleaners can fade, stain, or strip anodized aluminum, especially when they contain sodium hydroxide (lye) or other strong acids. Heavy-duty fast-acting alkaline cleaners designed for engine bays or wheels should not be used on anodized surfaces.

❌ WHAT TO AVOID :
High-pH (alkaline) cleaners
• Heavy-duty degreasers
• Wheels / engine bay cleaners
• Oven cleaners (e.g., Yellow Cap, Easy-Off)
• Products containing sodium hydroxide (lye)
• Damage the anodic coating 
Hot Surfaces
• Never wash in direct sunlight, as heat accelerates chemical damage
 Acidic cleaners
• Wheel cleaners with strong acids
• Nitric or sulfuric-based cleaners
• Aggressive aluminum cleaners
 Aluminum brighteners or etchers

• Products designed for raw or polished aluminum can strip the anodized coating

✅ HOW TO PROTECT ANODIZED ALUMINUM:

pH-neutral soaps 
• only use cleaners with a pH between 6–8
Wash on cool surfaces
• Avoid direct sunlight or hot parts
Test small areas first
• Always try new products on a small, hidden area
Safe Alternatives:
• Isopropyl alcohol (used carefully and sparingly)
• Mild Automotive Car Wash Soap

⚠️ RESPONSIBILITY NOTICE:
Damage caused by improper cleaning chemicals or detailing products is the sole responsibility of the owner. Keeping your anodized parts clean with the right products will help maintain their finish and extend their lifespan.
