CHEVY6000VHO

I hear you. The only thing about the leaf spring drop is that it lowers the truck too much. It's considered a 4" drop, but it actually lowers the VHO and SS trucks a tad more than 4" in the rear. It causes the rear to sag. You have to lower the T-bars down to get a level ride. I don't want more than 3 to 3-1/2" drop in the rear. The truck sits nicely right now, but the vibrations from all of this look really isn't worth it. Check my update in my other thread in this section. You'll see why I'm getting a bit frustrated from what a computer program anlysis told me. Jim

Where did you get the 3* shims???? Everyone seems to say they do not exhist. Belltech, Ground Force, McGaughy's, and other shops cannot seem to find these 3* shims that are 2-1/2" wide. The carrier bearing relocator has helped since today it was raised up higher. I haven't raised it as high as it will go yet. I'm also using 2* shims. Which way do you have your shims installed?? Fat side facing the front? I have a slight vibration between 35-45mph, but that's it. I'm not sure if it is going to be in the carrier or pinion angle. I took it to a driveshaft shop today (Randy's Driveshafts). The shop foreman Andy took readings from under my truck with a digital angle finder and measured the length of both driveshafts. He then input the nubers into a computer software program. He said that it should not be vibrating with the anlysis the program gave him. So, if that's true, why is there still a vibration? He told me if it still vibrates, to bring the entire driveshaft assembly and yokes to him and he will check them for being out of round and high speed balance them. I can't believe this vibration crap from just a 3" drop in the rear... I'll never lower a truck ever again after all of these issues. It's just not worth the headaches. I could have had my mods installed by now..... Jim

I already have a custom adjustable carrier bearing relocator bracket. Raising it will require a 1/2-3/4" tranny mount spacer. I don't see how switching to Belltech hangers will fix anything. I also have Caltracs installed, so I don't get much flex from the bushings ,just the rear ones. Belltech's hangers will not allow the use of Caltracs without modifying their hangers. I guess I will have to look for another shop. They don't seem to be able to fix the problem. I will look for a chasis specific shop I guess...... This shit sucks. I will not install any of my go fast mods until the driveline is fixed. Jim

I already have that......... When I use it, it places the tranny u-joints in a bad angle. Jim

I have found that raising the carrier bearing up gets rid of the vibrations......but the angles on the tranny u-joints go beyond the maximum working angle of 3*. I just don't understand why these kits are sold like that, without instructing you to measure the u-joint angles at the tranny. I had a custom one made to try and help allow the correct u-joint angles, but have yet to see that raising the carrier bearing is a good thing. Is there no other way?? Jim

How many of you ECSB VHO guys with a 2-piece driveshaft have lowered the rear 3-4"???? If so, what all was needed to get rid of the vibrations from this? I'm up to 4* shims and have yet to get rid of all the vibrations. I've used 1 & 2* shims both ways and those did not fix it. The 4* shims (installed with fat side to front) seem to get rid of the hard acceleration vibrations, but I still have a low speed shudder around 10-20mph under normal driving. Anyone here have any of these problems? Jim

Mister P, To try and make a long story short, I've been battling to getting my driveline vibrations resolved for the past 3 months or so. I've been told by quite a few people, that you may be of some assistance. I have a 05' VHO ECSB. I lowered the rear 3" with McGaughy adjustable shackles and hangers. Front with Belltech 2" spindles. I've had vibration issues from the get go right after. 3 different ones actually. One was a low speed shudder from 10-20mph, vibration under hard acceleration and another at 60-65mph. I have since then found that 4* shims with the fat side to the front has taken out all hard acceleration vibrations. I've also had a custom carrier bearing bracket made to allow full range adjustment of the carrier bearing. The problem is getting this low speed 10-20mph shudder to go away. It's only felt under normal light acceleration at those mph. The only way it seems to start to dissapear is when you raise the carrier up very high into the truck. Though that causes another issue of putting the u-joint angles at the tranny at a bad angle. It places more than 3* of angle on them. More like 4-5*. Is there a solution to this??? I'm at the point of surrendering to this truck already and selling it or putting it back to stock......... Belltech says that they haven't seen a GM truck need to use a carrier bearing relocator kit with just a 3-4" rear drop. McGaughy isn't any help at all. They are actually pretty rude. I currently have it at a shop. They are "trying" to get this low speed shudder to go away. They think it is no big deal, but I do. If you hold the truck at 15mph using the brake slightly, the shudder can be felt quite a bit. I don't know what to do anymore.......... HELP PLEASE!!!! Jim

SOLD!! Jim

PRICE REDUCED! Jim

ttt.... Jim

Price updated! Jim

Just to update, this item will be placed on Ebay soon. More than likely it will be this week. Once it hits ebay, the price here will no longer be valid. I will make one final post the day before I decide it goes on Ebay. Thanks, Jim

Need the money. Wife hounding me way too much lately about what I've spent on truck. Will be buying house soon as well. Jim

Yeah, that's the size of the Radix unit. It's the intercooled one for our trucks. It's the one everyone is using. The part# of the kit is posted in the 1st post. It is listed under Magnachargers website. Jim

I'm very tempted to selling it to you as well!! Jim

ttt...

My Belltech Nitro shocks did not raise the truck up at all. I too am using the McGaughy 3.5 kit as well out back, but opted for the Belltech 2" spindles for the front. I had a custom carrier bearing bracket made to allow perfect driveline angle adjustments, and to also eliminate having to use any more than a 2* shim out back. Jim

I'm selling my MP112 Radix kit. It's intercooled and comes in the powdercoated silver satin finish. It has the tunning software for all 05' & up Silverados.

Looks good, but that way lower than what I would want. That low isn't good for towing. I know you can add air bags, but it's just too low for most trailer hidths. You would have to put a raised hitch on, and that actually places more stress on your frame from the weight of the trailer twisting at the frame upon sudden stops. You want the weight dipersion more even with the frame. Anyways, I said too much. Comes down to this for me: 2" spindles+ 2" shackles + 2* shims + 4 Belltech shocks. I'm still contemplating on if I should do the Caltracs or not. Since I already have them that is. Jim <{POST_SNAPBACK}> Oh, I forgot, should I use my carrier bearing relocator bracket? Jim

Was that lowered in the rear with just 2" shackles? Did you guys use any shims? Jim

That's true, especially when I have a two piece driveshaft and most of you guys here have a one piece. Jim

Thoughthe pinion angle doesn't look like it's easy to find by just measuring the pinion's angle. Here's what I found that you need to measure: http://www.baselinesuspensions.com/info/pinionangle.htm Now, it would have really helped to know what the proper angle of these two measurements needs to be at. Looks like the driveshaft will need to be removed to get proper measurements. Jim

Doesn't it depend on the type of drop though? If you "just" do shackles only, then the pinion will definately be pointing more towards the ground. If you do hangers & shackles, the pinion may or may not be the same way. It could face more upward. Not sure, but it was a guess. If it is pointing one way or the other, the shims would need to be either placed in from the front or from the back. That's why I really didn't know what was correct and what was not. Your truck has hangers and shackles. So is it possible your pinion angle would be pointing in a different angle than a truck with just shackles? That's where my confusion lies at. Jim

If you know the correct answer, then why didn't you post it? I see that you ask a lot of questions there as well. If you know the correct answer to the question, then post it. Nothing funny about it really. These are forums to learn, not make fun of. IMO Sorry to crash the party here, but lowering trucks isn't anything anything I have hands on knowledge of. I would have liked to know the correct answer to it as well. Jim
