Finally got my ZR2 sway bar end links and I am very happy with the result. They were back ordered and it took about six weeks for them to arrive. Once I got them installed they completely solved the clunking and rattling noises I was getting from my front suspension after I installed 1.25" leveling spacers.
The install turned out to be very easy, however there were no included instructions. Perhaps they thought the install was so straight forward and obvious that instructions weren't necessary, but there is a trick to it. You have to leave tires on and the truck on the ground. Do not jack it up. Then remove both sway bar end links so that the sway can can be rotated. The ZR2 has plenty of ground clearance and the end links are easily accessible. Rotate the sway bar up so that there is enough clearance for the new extra long end links, and install. Pretty easy once you know what your doing. I tried to jack my truck up to let the front wheel drop down far enough to clear the new end link. This did not work. Don't bother doing it this way. Having instructions would have saved me a lot of time and frustration.
