52" springs up front provide a bang for the buck when it comes to lift and flexibility but it does come at a cost. Most that I know that have done it rave about how they flex out on rocks and off road. On-road manners suffer with a lot of sway and the springs tend to wear out quicky if pushed hard off road.

Part of the issue comes in for the road manners is the stock sway bar setup won't work due to the required change to cross-over steering. ORD does sell a new sway bar kit that works with cross-over steering to address the sway issue though.

So I guess to answer the question with a question is what is the intended use of the K5 with 8" of lift and only 35-37" tires? An early K5 can clear 35"s pretty easy with only 4" of lift. Here's my take, unless you want max flex on the cheap and plan on serious rock crawling the 52's are a quick way to go. If you plan on running this on the street regularly I'd look into some stock length custom springs or at least Tuff Country EZ rides. They will still flex well, but work with the stock steering and sway bar and hold decent road manners.
