Review on Moog K160039 Coil Spring Insulator by Jacob Ashman

Great factory spacers, I decided to replace mine as the jeep had 120,000 miles on the odometer and the originals looked pretty worn. They were very easy to install and ride well. They're pretty expensive, so if you don't care about originality and want a good ride, go for the poly, but I wanted my Jeep to be as close to the factory as possible.
