My Bilsteins Have lasted 202,000 miles and likely your truck also has factory Bilsteins. They are built to last, ride smooth, and are proven to be the best shocks for these trucks. UPDATED Realized I should mention that After 202,000 miles the truck still rides smooth on the road and on rough terrain you can barely notice the bumps. Only problem I have with the shocks is after 202,000 miles the truck is boatish because the shocks are soft and my rear has sagged a bit, yet the shocks wern't built to last that long so not the fault of Bilstein. I plan to install new Bilsteins in May because my factory ones make me trust the new ones will last just s long and ride just as well.
