Recommended rear shocks

I have an 07 dcsb with Dakar leafs in the rear. I had 5160 shocks that I was very happy with, but I went out to my truck the other morning to find my driver side shock had puked all the fluid out over night. Bilstein said if it was a 5100 it would be covered by warranty but 5160's only have a 90 day warranty. I could understand if I had bagged on my truck, but it's been a highway princess so far. Just looking to see what other people are using and happy with. I am not a fan of the idea of buying new shocks every year

 

Every vendor I talked to said 5160s weren't long enough to safely run with the Dakar pack. Try 5100 extended travel rear shocks.

 

Thanks!
