springs vs\' blocks

Which is better for a 4"-6" lift, springs or blocks and why? Which is best for flex and which is best for general purpose?

Re: springs vs\' blocks

Blocks are going to increase axle wrap up, but keep the ride the same as stock, new lifted springs will ride stiffer, but there will be no axlewrap. I see you have a 454, so you probably will want to avoid the blocks or you may have some major problems with axle wrap up. Another option is a shackle flip from http://www.offroaddesign.com

Re: springs vs\' blocks

I have to agree with Brian. Recently installed 4" with blocks and add-a-leaf. I now have a very stiff ride with axle wrap thrown in for good mesure.

Re: springs vs\' blocks

I saw those shackle flip brackets and threw those on my option list. One thing I can't figure out is how I'll get 1 ton suspension for the rear. Does anyone make a 1 ton leaf spring with a 4" lift built in it? If not, could'nt I do the shackle flip brac. and put stock 1 ton springs on? And, would this eliminate the need for traction bars?

Re: springs vs\' blocks

Just curious as to why you want to use 1 ton springs. 1/2 ton springs would be easier (your truck is a 1/2 ton isn't it?), cheaper, and ride much better.

Re: springs vs\' blocks

The plan for the 1 tons is to pull a camper. I cant hardly put a load of mulch in the back without draggin my a$$. Would add-a-leafs help? What options do I have? Of course I still want a smooth ride but need the load capability too. What to do? Yes, it is a 1/2ton

Re: springs vs\' blocks

Well, with the 6" springs, or a 4" shackle flip with 2" springs, the rear won't sag as much. The 6" springs will sag, but not as much because there are now more leafs to make sag. With the shackle flip, you'd have 4" of lift back there that doesn't sag, so the only sag would be in the 2" springs. If you absolutely don't want sag, get one of those camper/towing systems that maintains the rear ride height. I know they are designed for stock trucks, but I've seen some that I think would work. Hope this helps.

Re: springs vs\' blocks

I have 6" SkyJacker springs on my 92 and they are great. And talk about holding up to alot of weight. I and a friend delivered phone books in town this spring with my truck and lets just say they were piled up as high as we could go. There were a ton of weight there if not more and although the rear was saging there was no way I would have been able to at all drive with the old stock springs. The SkyJacker springs not only give you that lifting arch but they also have much thinker leaves but at the same time giving you the same ride quality because of the smallers thiner leaves in the pack.

Hope that helps you out a little....Ryan

Re: springs vs\' blocks

They do make 1-ton springs for lifting the truck. The problem I ran into is that 1-ton springs are longer than 1/2
and 3/4 ton. I would have had to cut my shackles and move them. It would be better to go with a load-leveler from Hellwig or some such. Give you the towing capacity with whatever springs you chose. D.
