coils question

so thinking about getting billies to replace my current shocks because the truck drives really bad . Right now it has 103000 miles on and was wondering if i should replace the coils when i replace the shocks. Reason i ask is because i don't want to replace the shocks and then have to replace the coils 50000 miles later. Just as a point of reference i do a lot of driving in DC and the roads are crap.

 

If you have the scratch to do so then I would. One less thing ya know? You could do 5100s set at 0 with eibach coils...would only give you about 1.5" of lift. It'd level the truck nicely

 

and have a very comfortable ride

 

^^^^ x2 just get new shocks and coils
