Re: How can I level?
 

I would like to see how they look fitted.

I'm looking at the specs for the Moog 6560 now, they show an 11in install height, a 13.19in free height, with a 3289lb load, but the spring rate is 1501in/lb. The 6560S has a rate of 1464in/lbs.

The Moog 6454 is a 13.61in free height, with a load rating of 3841lbs, and a spring rate of 1060in/lbs, but the install height is only 10in. These are a match to the Napa part number 2772074.

I would swap the 6560S for the 6454, you'll have some money coming back if you do.

Re: How can I level?
 

Yeah, I did some search online and indeed the napa 2772074 springs are the same as the moog 6450. I just bought a set at autozone that had one in stock and I hope to get them installed tonight. If the 6450 work, I will post some pics of the different setups. Hope nobody else makes my mistake and try to in stall the 6450S, I reckon they won't be able too unless they have a backhoe or something to put a few thousand lbs on the front to be able to compress the a-arms.

Good luck I hope it works. Keep us posted and provide some pictures.

Re: How can I level?
 

Moog 6454 or NAPA 2772074 is the winner. The truck drives great, very stable and firm. I love it. I have two tires sizes on the front, on one side I have BFG KO 235/85/16 and 36-1/4" of fender clearance. The other size I have Goodyear 245/75/16 and almost 35" clearance. I have another goodyear tire that I was planning on having it mounted this weekend but plans have changed, I want that extra clearance so I will be on the lookout for another KO. I hope to post some pictures this weekend. Thank you all, Gio

Oh, best of all, I didn't have to use the backhoe this time, LOL.

Re: How can I level?
 

Congrats. Glad to hear that it worked out. I can't wait to see pictures. Please post pictures or tell us the measurements from ground to fender. I did a similar thing when I installed a lift kit on my '70 K10. I took measurements from ground to curved point of fender and also top of tire to same point.

Re: How can I level?
 

i know this is a old thread. Does anbody know if these springs will raise the front of my 1972 c/20 longhorn?

Re: How can I level?
 

Those should do the trick. I plan on using them on my C20 Custom Camper.

Re: How can I level?
 

ok, in reading through this I was wandering if all these trucks were running big blocks which would offset the weight quite a bit from my small block c20 application. Could I use the same springs to level my c20/350/4 speed truck?

Re: How can I level?
 

Did you ever do thiss Mod? I too have a small block and want to do it?

Re: How can I level?
 

Did you have to make any other changes to the suspension or alignment when you did this? or can you just pop the bigger springs in there, with the same shocks and ball joints and all?

Re: How can I level?
 

You'll probably need an alignment. I used the springs Dan posted and used the same shocks and ball joint. I love the look, it is noticeably stiffer

Re: How can I level?
 

Wow this is something I have really wanted to do and all of a sudden I see a new thread on the topic! I think my C30 LongHorn will look pretty good leveled out? What do you guys think?

Re: How can I level?
 

I wanted to check if these springs (NP 2772074 or MG 6454) are still recommended to do this front end lift. Its been a while since the posts and wanted to see if there are any new recommendations.
I was going to order the sprigs this week. Thanks

Re: How can I level?
 

I just ordered the NP2772074 springs to level the front of my '70 C20. I will keep this thread posted on results. I did however, have a question about what springs y'all are running on your C20's that you've liked the best. Please advise and thank you in advance.

Can you tell me what shocks you used with those front springs?
