Ok, I'm finally getting the ole girl where I think she needs to be for a multipurpose vehicle. My question isk, Who makes the flexiest front springs for the K5? I have some pro comps on it now and they are the 4" lift ones. I have extended shackles on the rear of the springs but If I have to remove them I would like to have some around the 6" lift range. I will keep the Shackles and run 4" springs if that will help it flex. I need some suggestions on these please.
 
Flexiest front springs

OK, I have seen the posts for the 52 inch springs. Are these the one's from the 2wd f-150? If so, what years do I need to look for? How do they handle on the highway? I have no sway bar connected, and I don't mind a little sway at hwy speeds but I don't want it to be crazy. I'm just not real clear on the advantages of doing this. Thanks for all the info. I'm still searching while I'm posting so it's not like I'm not trying.
 
52's are stock, 52" long rear chevy springs. You could just pull them out of the back of your k5.
 
52's by far are the best spring for the front that I have seen so far.

52" Rear springs

Now the stock springs equal how much lift? Will any of them work from a 4wd truck/blazer/suburban any years? Thanks again for all the info.
 
Mine came out of an 85 K5. All K5's should have 52's in the rear, and I think most 1/2 ton P/U's have them... some will have 56's, so take your tape measure.
The Ford springs you mentioned are 57's out of a 2wd F150, and they ride great on the highway, but too soft if you haul/tow much.
 
my swap gave me 5"s of lift, i had to pull the zero rate so it would sit level, in the back i have a ORD 4" shackle flip and zero rate

Whoa, sorry to steal the thread. You can take rear springs from a K5 and mount them up front for like 4" of lift?!??!

Basically, yes. And you also get 2" of axle movement.
 
Axle Movement?

What do you mean by Axle Movement? Still sort of a newbie so sorry for the ignorant questions. So, the factory rear leafs will get me around 4-5" of lift right? Do I need to reverse them when I install them or just take them straight out of the back and put them in the front like they come out? Thanks again.
 
the ecnter pin is in the middle of the springs so it does not matter whihch way you put them.
I springs will move your axle 2" forward.
Check out the search, there are alot of posts about this.
 
You will need to move the front mount forward too before you move springs. There is a ton of info out here on the swap, and PM me if you have any questions.
It will work, it will lift, and they are flexy...
 
What are you guys running for driveshafts with that kind of travel? My stock CV had to be ground just to clear at ride hight after a doubler (I only have 5" of lift also).
