I've done several searches on existing threads discussing add a leafs. I haven't been able to find much on how they affect ride / handling. I've been wanting to either replace the existing blocks with taller ones or an add a leaf. Can anyone give me any info on how the ride changed if any with an add a leaf? I would expect possibly a little stiffer / bouncier.

Done that on three of our trucks.

Your correct. It will be stiffer and the bumps will hurt a little more when riding empty.

Adding a leaf will simply stiffen your leaf pack causing a harsher unloaded ride. It definately won't be bouncier because you are increasing the rate of the leaf pack.

If you are looking for a car like ride, adding a leaf is not the way to go, better off with air bags IMO. They are very adjustable and are more bump friendly than adding a leaf.

i put a zone kit in my 11' it rides like a 3/4 ton now but i got a good 2 inches of lift and takes around 500 or 600lbs to bring it back down to stock height

Yea, there just isn't very much info. Most of what I have seen on here relates to install. I just need to decide whether I want to go with the leaf or taller blocks. Adding the 3" block would bring the rear of my truck up to 1.5 inches higher than the front which would be good.

Adding a long leaf will do the same, plus give you a little more weight capacity.

^ thats why i wanted to add the leaf. you get 2 perks with the leaf, lift and payload. you cant get both with a block

Firestone Air bags are a much better way to go. Just put some on my truck a few months ago and they are really nice

True, IF you are always towing and hauling heavy loads....No need to spend that much money for a "look", or a little extra. Most people don't do that much to NEED airbags. But if you haul and tow heavy all the time, no doubt airbags are the only option.

Just remember, none of the additions to the rear leafs will add to the weight rating of the truck. They only help the truck sit more level when loaded. Just make sure you dont overload your truck.

 

I added them to my truck and they did increase the height of the truck, but it also increased the stiffness of the ride. But, I am used to 3/4 trucks so the ride was not bad to me. I would recomend AALs over taller blocks every time. If you increase the height of the block, you also increase the risk of axel wrap. To me, the slightly harsher ride is worth putting up with more than wearing out my spring early do to excessive axel wrap.

 

Its just a trade-off and depends on what is more important to you.

Adding a slightly larger block is not going to cause your driveline to bind and cause axle wrap. That's not going to be an issue, mostly an issue with vehicles with very soft leafs in the rear, and vehicles lifted to the sky.

 

It would be a little different if you were going to add a 8" block, then you would have to be worried. That's why a lot of highly lifted trucks have ladder bars installed, to prevent the issue of the pinion angle changing to the point of driveline bind.

Im not saying it will be so severe as to completely destroy your truck. But, even the stock block causes some degree of axel wrap. Granted, like you said, its not a big problem until you really jack it up, but it will be worse with a 3" block than a 2" block. I believe (my opinion) that the block, coupled with fewer leaves per pack, is the reason that so many 1500 trucks experience the slip yolk clunk, which is a direct result of axel wrap allowing the drive shaft to slide excessively during acceleration, braking, or directional changes in the trans.

 

Will the results of adding a taller block be catastrophic? No.

 

Are the odds greater that the springs would wear prematurely do to a taller block and slightly increased axel wrap? Possibly, but not to the point that it would cause a total failure.

 

I know lots of people add a taller block with lots of success and no problems. Im just in favor of AALs because of the increase in height without an increase on rotatinal motion on the springs.

      Thanks!  I figured as such; GM and other manufacturers have used standard parts and harnesses across trim levels and such for decades.  I pulled the blank accessory cover off of my commuter van (a 2016 or so Chevy 15-passenger) years ago and found the plug for a USB outlet.  It wasn't connected to anything, though (I tried swapping in an outlet from another van).  I was a GM Tech years ago (late-90s) and was pretty familiar with my 2006.  I might be wrong, but I view newer vehicles (pretty much anything made in the past 20 years) as being a lot more plug and play.  Meaning, more unused wires and plugs unless you have the Mack Daddy of vehicles.

      not all plugs will be used.  gm uses more generic harnesses that support most/all options, and if your truck doesn't have a specfiic option, the plug won't be used (commonly will have a dummy insert in the plug , or it'll be taped up, but some may just be left as is).  But it's sldo possible some p.o. has installed the wrong/cheaper parts that aren't correct for your vehicle...

      First off, I'm not trying to just get easy advice/fixes for the issues I've noticed so far.  I'll be combing through the site via searches and such, and if past experiences are any indication, should find what I need.  For the sake of conversation, though, I figured I'd post the handful of things I've noticed in the 12 hours since buying my 2010 SLE CCSB.     Indicator lights: Airbag and TPMS.  The tire pressures aren't reading for any of the wheels, so I'm pretty certain the sensors were either removed, are damaged, or are otherwise inoperable.  I used to mount and balance tires 25 years ago but am pretty much ignorant when it comes to TPMS.  My 2006 didn't have the sensors and this might be the fourth vehicle I've owned that does.     Radio: Rear speakers aren't working.  I removed the driver's side rear door panel and checked the speaker and wiring.  I also removed the sill and b-pillar covers to check the wiring.  A few minutes of Google Fu showed that this is potentially a head unit issue.    Switches: Power mirrors don't turn left/right.  I ordered replacement driver's door switches that should arrive tomorrow.  The windows and locks work but it was only about $20 for all of them.  The driver's side rear window switch lets the window down but won't put it back up.  I think the passenger rear doesn't work at all.  In the coming days/weeks, I'll break out my multimeter to check all of that.   Unknown wiring harness: There's a box attached to the front driver's side of the engine compartment, right where the second battery shelf is located.  There are three plugs, one of which looks like it fits a standard headlight-style bulb (9007 or similar).  It doesn't look like it's plugged into anything.  I'll do some digging and if I don't see anything elsewhere on the site, post some pictures here.   Unknown plugs on brake booster: There are at least two female plugs on the brake booster that aren't being used.  I think it might be a replacement/aftermarket, so maybe those are used for a different application, as there don't seem to be any unplugged harnesses and no indicator lights are on.   Little squeaks when turning: Sounds almost like a bushing around the bed of the truck.  I'll have to pay close attention as I get more familiar with the truck.   Clunk on acceleration: possibly the infamous drivetrain clunk.  My 2006 had it and I'm just not familiar enough with this truck yet to fully grasp what it is.   Anyway, my apologies for the vague and all over the place post.  This truck is new to me, and it's been four years since I drove my 2006.  With 200k miles, I know I'll need to learn this truck quickly to avoid having any major issues, despite being confident it's got much more life to it.  My 2006 had nearly 320k on it when I parked it (nearly 300k of which I put on the truck), and it was still drivable then, though I suspected the head gasket might have blown.  I'd hoped to have that truck back by now, but it's gone forever, as I detailed in my reintroduction thread.
