Dynatrac tubular front lower link kit for the Jeep Wrangler JK, SKU DT921031. Dynatrac lists it for 07-UP, and the JK ran 2007 through 2018. These are fixed-length arms that replace the factory front lower control arms.
Dynatrac says the arms are stronger than the stock ones and improve alignment specs on a lifted JK. The bushings allow more range of motion, which lets the suspension move without the bushing bind that limits the factory arms.
