Their double adjustable control arms have some marketing hype but have replaceable joints with decent flex and don’t require grease.
Does unicorn jizz not count as grease? Seriously though, metalcloak does recommend greasing. That allows the joint to rotate in the housing, vs a JJ where the ball rotates in the bushing.
