Synergy Manufacturing 4170-04 Heavy-Duty Ball Joint Kit 1 Upper / 1 Lower, Knurled for 18-25 Jeep Wrangler JL & 20-25 Gladiator JT
Please Note: This style ball joint requires a 100-500 mile break-in period to fully seat the bearing surface. In the interim, your steering may feel slow to return to center or a bit sticky. As the break-in period ends, you'll notice excellent, smooth, tight steering.
Increased Durability: Upgrading to these metal on metal heavy duty ball joints are a huge increase over the factory metal on plastic ball joints.
Options: Whether you are replacing just two worn out ball joints or upgraded all four at once, there is a selection available for you.

Synergy Manufacturing Heavy-Duty Ball Joint Kit Reviews
Would recommend going with dynatrac pro steer set. More expensive but well worth it. The synergy do not compress fully and there’s not nearly as much steel on steel contact with knuckle and ball joint in the synergy as there is dynatrac. I installed the synergy ones but removed them once I saw how weird and not fully touching all the knuckle it should have.
