This is the only place I will shop parts again.
These parts are 100% identical to factory and fit perfectly and the videos on the 1Aauto website were a huge help and the prices are amazing. My truck rides and handles so much better now. I won’t buy parts anywhere else now.

I ordered these since the lower ball joint was unservicable. The fit was perfect and the installation video made it easy. The arms even included the shock absorber sleeve. You simply can't go wrong with 1aAuto pricing. Very pleased.
