Bestselling F-150 Raptor (2021+) Rear Billet Upper And Lower Link Arms W/ Ultra-flex Joints For Men [hMCi4p3q]
Extreme Durability - The Ultra-Flex joint design allows it to last significantly longer than a conventional uniball joint.
Less Noise - the urethane in the joint helps isolate the road noise and wont squeak or clunk like uniballs when they get worn out
Resistant to corrosion & rust - All stainless-steel components stay constantly lubricated - making this a great solution for areas that have humid / wet weather.

Easy to Service - Low profile external zerk fitting allows you to conveniently add grease to the joint whenever it's needed while the suspension arm still remains installed on the truck.
Saves You Money - Instead of having to replace the complete uniball assemblies, the Ultra-Flex joint allows you to just change the urethane replacement body that may wear out over time - this saves you money in the long run compared to the the cost of replacing complete uniball assemblies
