Blocks, Springs, Shackle Flips....Oh My! (Another suspension question.)

[budbeater]

My truck is a 71 K20. I have had it for just over a year and I am starting that whole rebuild thing. Before I dive into sheet metal repair I have to go from a 4" lift to a 6" lift to avoid recutting the fenders. The previous owner cut the fenders and that lead to a total cab rot-out.

I am planning on a 6" Tuff Country Suspension Kit. I am doing this for a couple of reasons 1. They are a local business and I believe in supporting my local economy 2. They seem to have a very recommended product.

My question is: DO I GO ALL SPRING, SPRING/REAR BLOCK, SPRING/SHACKLE FLIP/FLATTER REAR SPRING?

All spring would be (in my opinion) the easiest.

Spring/ Block would be the cheapest.

Spring/Shackle flip would be the most aggressive for off road.

The next question would be "How do you use your truck?"

The truck needs to be an "everything" vehicle. It will NOT be a RockCrawler or even a Hardcore Moab vehicle. My idea of hard 4wheel use will be torn up fire roads, muddy/rutty hunting trails, water crossings, dirt, snow.

I have to use this vehicle to tow a car trailer (race car and trailer weight about 6000lbs). I would like it to be 8000lb capable, but that isn't a deal breaker. I am wondering if the 6" Tuff Country springs will have significant sagg under 3-4 tons of towed load? Or would blocks be better? The towing is not an every week event.

Main use of the truck is daily 6 mile drive to work. I don't mind the 3/4 ton ride, but the bounce gets old some days.

I am not sold on the shackle flip idea, but tell me the positives (does it ride better, does it tow better?)

Thanks for the input
