Dont match identical to OE parts
It advertised to be identical to factory parts but they are not. The parts were not a good fit and do not look to be durable. I will pay the extra cost to get better brand in the future.

Suspension kit A good replacement for OEM parts
Received quickly and is a good fit . Appears to be of good quality only time will tell . fairly easy to install if you follow instructions and be sure everything is cleaned ahead of time , and use penetrant first. I recomend this set .

Lower ball joint did not fit and broke
All parts went on with ease and seemed to be of good quality (Although i have not driven on them yet due to ball joint issue). When pressing in lower ball joint, the sleeve used to press pushed against the rubber seal of the ball joint causing it to tear and the rubber fell off. Comparing these ball joints to higher quality ones, youll see these have the rubber sealed around the outer lip, whereas the better ones had just the metal lip which is where the press collar sits to press the joint in. This is a manufacturing flaw and I will be working with customer service to hopefully get a refund so I can buy a better joint. Other than that, again all other parts went in smoothly and appear to be high quality and comparable to OEM.
