Okay im do a full width and SAS on my runner. I already have a set of chevy 63's to go out back with my 14 bolt. How do i know which springs i should run up front though? Obviously i will need it to sit level. but where do i start?

 

Here's a good place to start.

Otherwise, I think you would probably go with 3 or 4" springs to match the rear.

 

Link to my brothers 1ton Toyota build

He is using 51" Toyota rears. Toyota rears are nice because you can make them anyway you like, and they are cheap.

 

I WOULD SCRAP THE LEAF SPRINGS AND GET 4-LINK AND COIL OVERS, http://f-o-a.com/ HAS ABOUT THE CHEAPEST COIL OVERS IVE FOUND YOU WILL GET WAY MORE FLEX AND IT IS NO HARDER THAN LEAFS TO INSTALL

 

OMG ARE YOU YELLING? OR IS YOUR SHIFT KEY STUCK?

Seriously, I've never installed a 4-link, but you can't convince me it's easier than leafs. Triangulation confuses me.

 

4 link and coilovers takes much more money, time and fabrication, hanging a set of leaf springs is simple, cheap and and for the majority of people they work very well.

 

Wow, easy there killer

I prefer leafs for my part of the counrty, wheeling style, and rugged simplicity.

I say Marlin leafs.
