I have 55k miles on my 2006 F150 KR 4x4. Just curious how long the shocks should last. I do some towing with it (4500 lb boat & trailer). It's about time to buy new tires, and I thought I might do the Bilstein shocks at the same time.

They are probably pretty well gone by now. If you change them, depending on what you buy, you will notice quite a difference.

You've gotten about all the usefull life out of them you can. Go ahead and change them.

Thanks guys. Since my Nittos are pretty well warn, it's hard to tell if the rougher ride is the shocks or the tires...or both. I think I'm going to take off my AS leveling kit and put on the Bilstein 5100s with my new set of Nittos.

50k is a pretty good life for shocks, some people hang onto them for 100k+, but if you're towing, you want to be as stable as possible and driving around with bad shocks won't be a great idea.

You can see all the parts we have, including the Bilsteins for your truck here:

The 5100s are a great choice because they can level your truck with 0.5-2 inches of lift and are valved stiffer than the heavy duty shocks, so they'll give you MUCH better handling and control.

Do it, you won't regret it.
It was a nice and welcome improvement installing 5100s with 30k miles on the factory shocks.

ShockGuys...
