I have heard on this site that to raise the rear of this truck to better match the front I should use add-a-leaf instead of adding a block. However, a local shop told me today that adding a leaf would further stiffen the suspension and make the ride too rough. Adding a block would raise the height, but not stiffen the spring. They recommended adding a 2" block. Is stacking a 2" block on a 3 1/4" block safe?? If so, I will do it. Thanks for any opinions.

 

No...stacking blocks is NEVER safe. The AAL will not stiffen up the ride that much.

 

yes rom is very correct never ever stack blocks, your just asking for trouble. The add a leaf is safer and you probably will hardly even notice a stiffer ride if you do at all. Its not as drastic as they make it sound.

 

2" block isnt that bad, i have a 1.5" on top of the stock one, and i wheel the s^%t out of mine, with no problems.

 

You should never never never stack blocks. [sm=nono.gif] I would never go back to that shop if that is the kind of advice they are giving you. It is not safe, period, so why take a chance. The lateral forces of an axle under stress can cause the blocks to turn on each other, severely weakening and possibly tearing up your u-bolts. When u-bolts fail, bad things happen. Why anyone would want to take that chance is beyond me. If you insist on running stacked blocks, at least weld them together if nothing else.

The AAL will stiffen up the rear a little, but I can tell you from having driven several flavors of 2nd gen Rams, a stock 2500 is stiffer then any 1500 with an AAL I have been in. So don't worry about it. Get the AAL. It is much better then blocks (which, if to big, also has the tendency to move your axle out of proper alignment, which will lead to axle wrap), and more importantly, safer. Plus you get the added benefit of being able to put more in your bed before you start to see it sag any. [sm=smiley20.gif]

 

I am now convinced that AAL is the right thing to do. Just wondering if 2" or 3".
I think I will jack it up 2" then 3" & see how both look before we order the parts.

 

block = no prob. here.. knock on wood

 

I am about to order a 2" Add-A-Leaf pair. I have a little over 1/2" of u bolt left and shop says that it fine, as only the thickness of the spring will impact the length needed for U-bolt.
I jacked the back of the truck up about 2" and it looked great. Has anyone ever been disappointed with the amount of lift not being enough as represented by manufacturer.
Will body weight take it down to less than 2" ? Thanks for any feedback.

 

only a matter of time before the stacked blocks fail....

go with the aal. much safer and very reliable.


ram_sport i'd get the welder out...

 

ha

small stacked blocks are not going to fail without reason. there is a steel pin in the center of the blocks to keep them aligned. there are steel u-bolts holding them from spinning. if you fail to maintain and install them correctly, there is a risk (lose ubolts, pins not aligned).

otherwise, i wouldn't think twice about running SMALL stacked blocks (5" total or less).

everyone says blocks, as a whole, are dangerous. dodge has beed using 3" and 4.5" (i think, for the 2500's and up) for years...if the blocks were falling out and destroying trucks and killing people, think they would still use them?

add-a-leafs severely limit flex, and make it ride harsher. hell, their whole design is to keep it from flexing, thereby raising the truck.
