I ran across these on the Expedition Exchange website (https://www.expeditionexchange.com/defender/
) and was wondering if anyone has installed them and can comment on the improvement/difference. The claim is they reduce transmission of road, suspension and driveline vibrations. At $14 ea they are certainly cheep enough assuming they help. They also have a ruberized shock tower securing ring for $29/ea. I will be replacing my shocks shortly and will consider these if there is any noticible improvement.
It also looks like it will add a bit of lift but the it looks fairly minor.
