Ok guys I am swaping in a 60 under the k5, and I would like yalls opionin on witch springs would be the best for the front of the truck 52's or 56in springs. I will mainly use the truck for trails and rocks and some mud(I hate cleaning mud), and I am all ready putting 56's in the rear w/ the 14 bolt this week. So befor I start the front I would like to get yall's opionin on witch set of springs would be the best?

thanks

I am currently doing this swap on my rig. Putting the 56" up front and 63" in the back. I built a new hanger for the front springs. Seems like it will work good. I will send you some pics if you want when I get them hung.

Ya I need one more set of 56's if I go that route,

bushwacker I would like to see the hanger you made, why didnt you just swap sides on the stock front hanger?

chris do you have a tire grover?

52's seem to be a less complicated choice ( pinion dive etc.) i had 56's mocked up and ended up with 52's. a few guys claim they work fine but not alot of info on it:dunno:
 
I have had both in the front of mine. I started with 56s but went to the 52 and like them better so far. Pinion angle is better with the 52s. I had a 8* shim in with the 56s but then my draglink would hit my pass side tires and it was just one thing led to another deal.
 
I made a new front hanger out of some 3x5 tube and cut new spring mounts from some square tube. I basicly wanted a couple more inches than what the springs alone would give. I will try and post a pic but seems I never can get that to work.

not yet, I am waiting on some parts to come in from ORD and I hope to have them hung sometime this weekend. I will post some pics along the way. BTW, that avatar of yours is too hilarious!

I run the 56's in the front. Im curious as to way ur having pinion issues.... My angles are great. but i do have a doubler and my front end is pushed 3.5" forward.
 
Since the 56s are asymmetric the rear 30" of the spring tends to bend more than the front 26" of the spring. That means as the axle droops the pinion points more towards the ground. My driveshaft is 40" long collapsed and I have my transfer case clocked flat... not a big deal for me but for a more normal-length driveshaft (say, 32") it is a big deal.
 
my prob was with the pinion pointing down as mentioned then running a clocked up 241 just too much angle. I prob could have gotten away with less shim but that is what it really needed. Then by adding shim and with the thickness of shim and the thicker spring pack it brought my crossover draglink an inch from the spring at static since it rotates down with the axle rotation. Then when flexing it would hit. Went to the 52 and everything is alot simpler and worked pretty well. If you use your front spring hanger drop along with 56s it should work really swell though.
 
I had 56's first and then 57's. Pinion angle was a little rough when it came to both but nothing to bad. I also ran a clocked 241 (sat flat in the frame) I had a square shaft and all was good.
