Not to change the focus on the pumps/filler necks. But about 6 mos. ago i noticed a puddle of oil under one of my generic coil over shocks, if i remember correctly they came with the 4 link system from Alston. I had purchased a set of QA1's for my prostreet Sonoma, but with 110 springs. I had not mounted the shocks yet, so i decide to use them on the Malibu (same length), but i had to order a set of 130 lb springs, imagine my surprise when i opened the box, the plastic bag the springs were packaged in had a label on each bag MADE IN CHINA. Now the original shocks and springs had been repackaged and didn't have these labels, go figure.
QA1's one of the most popular brand shocks around.
