I used factory shock absorbers until 160,000 miles with no issue. At that point I installed a 4 inch lift which included longer skocks in the kit. They didn't last long and probably were not good from the start. I wore 2 tires pretty bad in less than 20,000 miles. Two weeks ago I replaced the front with Bilstein. The ride and handling on my F250 are improved (hadn't noticed it was bad before though). I definitely recommend these shock absorbers.
But a different brand of sharks they were out extremely quickly I bought bilstein 5100 and had them on my truck now for 10 years Great shock for the money
