NNBS Rear 5305 springs

[lowexpo]

Surprised at seeing this under my '07 Tahoe, 3rd row out and nothing in rear. These are the 5305 Belltech springs. Got helper bags to smooth out ride and make usable again. Is this what everyone else is doing?

 

[iwaslowr]

Are those lower coils touching each other? Do you have any pics of this spring in a non- compressed state/pre-installation?

 

[houstone003]

mine used to do that as well but i cut the deal coils to drop it more

 

[GWEE]

That doesnt look right or good.

That's what those coils do. I think NorcalSS has some pics of this on multiple trucks. Anyone who tows/hauls eventually adds those helper bags. You are on par with the other owners.

 

[lowexpo]

@iwaslower, yes they are touching. I dont have uninstalled pics. I've been around lowering products for over 20yrs and never seen this. Been on truck about 2 months. @houstone003, Not looking to go lower, been there. @GWEE, you are correct

Alex33, I'm just surprised at this cause as i'm sure you know how a spring works. Just figured Belltech would make a better spring. I did a search before buying but didnt see pics...

That is perfectly normal lowexpo.
1. They are closely progressive wound coils on a heavy SUV. That's why they touch.
2. There is a 1" spacer installed which is making them touch more than they would w/o it.
3. They are installed wrong. The closer wound side goes up.

Modded is right.

They are UPSIDE Down for one. You do have a spacer too.

I just did the 2 inch rear only on my Suburban. My coils just barely touch, no spacer.

I wish there was another design.....because it just looks wrong IMHO. Defeats the purpose of a "progressive coil" to me.

The Belltechs seem soft to me, so I just ordered Airlift 1000s part number 60742. It is a 4.9 inch wide by 6 inch tall bag.

The one thing people lowering don't realize is that it will sag and or bottom out when fully loaded. I just hauled 5 people plus a piece of luggage for everyone and my Suburban was rubbing the 275 20's in the back.

It looks darn good, hopefully the bags with bring back my full hauling capacity.


@Lowexpo.......... Do yo have the bags in already, post pics. What model.

 

[Alex33]

Dang, beaten to the punch (so to speak). Anyway, I hope these guys were able to assist you lowexpo. I was searching the forum for some pics to help you out but my slow connection drug out that process.

Now that you have this new info, hopefully you can get it corrected with minimal inconvenience.

 

[NORCAL SS]

5305 normal on that and they are installed upside down.

WOW! my rear drop springs dont look nothing like that but I am about 3 inch dropped in the rear, the top coil barely touch each other., To me it seems like the shocks are doing more work than the springs since they are compressed so much, correct me if im wrong.

 

[Goodinblack]

@ lx4life Post pics............^^^^^^^

What springs?

 

[lx4life]

i wil take some tomorrow afternoon

 

[lowexpo]

Well crap... Haven't put bags in yet, i'll get pics up when i do. I'll even flip the springs since I have to remove anyway. I have the Airlift helper bag kit. When i jack rear up and inflate bag will i be able to remove spacer? Not a fan of spacer but looks ghetto without it. I hope to install Airlift kit this week and I'll get pics up.

What airlift kit number did you get?

What do you mean

[NORCAL SS]

just put spacer up top been using them since late 06 and no issues on any truck that ive sold or installed on.

 

[lowexpo]

@Goodinblack, I read in another post to fill bag before letting jack down to get more lift since spring wouldnt compress as much with bag inflated. Wondering if bag would compensate enough to remove spacer. @Tony, ok

@Goodinblack, not sure on part# I'll check when I get home tomorrow.

 

[lx4life]

Here are some pics of my drop springs.

 

[lowexpo]

What springs are those?

 

[lx4life]

I dont know it doesnt have any numbers or markings, it came with those springs when I bought the truck
