i recently upgraded my automotive shocks to the C1608054 and I am impressed by the difference it made. Through trial and error, I found that these heavy duty shocks provide a smooth and comfortable ride even on rough terrain .The improved suspension has also increased my vehicle's stability while driving at high speeds. The only downside is that they can be a bit pricey compared to other options on the market. Overall, I highly recommend these shocks for anyone looking to improve their cars performance..
