I bought from UMI for their good reputation and I don't regret it. I feel that Duane at UMI has been really helpful and that means the most to me. I wouldn't hesitate to buy from them again. I would just call them first to discuss my project.

When you're building cars there's always something that can go wrong and this to me is a minor issue. This car is 33 years old and I have no idea what it's been through before I got it. Since December this car has had new paint, new interior and an LS swap. This isn't the first problem I've had and it won't be the last.

Also don't forget human error. It's possible I have the springs in wrong or somehow there was a mix up in manufacturing. Duane said if I did send the springs back they would test them, but I need to get this thing to the tire shop soon. So I chose to cut them.
When you're building custom cars or trucks it's easy to get a part that doesn't fit or work quite like you thought it would. Prior to this car I built a '51 Chevy truck(see photo below) and I lost count of all the times it happened. I have had 3 different engines, 2 rear suspension and rear end setups and 2 different front brake setups on there. If you expect every thing to go perfectly the first time, this might be the wrong hobby.

To me it's about the customer service you receive when something does go wrong.

Hey guys. We appreciate the support and the criticism. UMI got where it is by both excelling and yes, by making mistakes and fixing them. The difficult task of deciding why 0.37% (real number I pulled today on units sold vs complaints over the last 365 days) of cars don't sit right with 3050 and 3051 springs is my challenge. We'll see what we can do to make that 0.0%.

In the meantime, here are some springs working well. :cool:

I wanted to see if anyone had a similar problem and how they resolved it. Obviously I didn't get that.

What I didn't want is people that haven't dealt with UMI or had a similar issue start bashing them. I appreciate all of the information and help on this forum and would be happy to help anyone else,
And I felt like I have resolved the issue talking to Duane.

Ummmmm post number 3.

I have the issue as well.

Not as bad as yours but still have it.

I have dealt with UMI's customer service in the past and was completely blown off.

I had purchased a set of their front lower A-arms with ball joints for my Malibu.

What ever ball joint they were using at the time were complete junk.

I called and got no help at all.

Basically I got a yeah we know oh well.

This was about 6-8 years ago

I gave them another shot after all this time being they are a sponsor here.

I bought the 2 inch front and rear spring set.

Well like I said in post 3 the front sits higher than the rear and after 6ish months they haven't settled or changed.

Did I call UMI about it?

No simply because I didn't want to get blown off again.

And right here in post 16 the answer to the problem is to cut the spring?????

I don't like calling out a forum sponsor but whats right is right.

Hey Jweb - i had the same exact problem with my 2" Lowering Springs from UMI.
They were installed correctly and jet the car sat higher than it would stock.
With 205/75R14 tires on stock steel wheels, ground clearnace (bottom of side frame rail, below the a-pillar, measured to ground)
was an astonishing 8" inches. The rear went down a little bit but probably the same hight as with my worn out Springs.

I also talked to UMI and they said that there are many factors as well as my Enigne weight. (267cui)

I Still refuse to start cutting my springs -- like, serious? I could do this with some $10 Stock springs.

I Finally went with OPGI 3Inch springs and they where just PERFECT!
I didn´t want to let my first post to be bashing UMI - but in this case i was very disappointed since i had them
shipped all the way to germany which as you can think isn´t cheap either.
But i can´t say anything bad about the Customer Service - they were quick with their responses and tried to be helpfull.

I wouldn't cut them, given the cost I'd ask Umi to take them back on their dime and tested. I'd also ask that another set be shipped on the quick, spring is right around the corner (pardon the pun).
Umi is a reputable manufacturer and I'm sure resolution is imminent....

One other thing, it was mentioned that the spring needs to be seated properly up top, I know that the bottom tail needs to be seated just right on stock a-arms too but I assume this has been done?

The question you have to ask yourself is: 2" drop from which factory spring set up?

Base V6 car with no options?
Up-spec V8 car with all the options?
Base V6 car with no options except the F41 suspension package?

Too many variables to gauge on a single set of springs for both the vendor and buyer when it comes to these cars.

A G-body it isn't like a late model Camaro which has just a few options packages and tight manufacturing tolerances.

Personally I am not paying top dollar on parts I know I am going to have to modify to suit my application. MOOG has a $20 ~800lb/in spring set that I smile when I chop up. However, UMI has lots of my money on other parts which are properly designed to almost all applications across the platform.

What shock absorber brand and part number did you use with these springs?

I did see that you had a similar experience but I wasn't sure how you resolved it. Now that you have provided some more info I can see why you're unhappy. I also see where a few others with good info have now commented as well. I have dealt with many aftermarket companies and several just say "that's the way it is" or "you installed it wrong". I didn't get that from UMI and it's unfortunate if you did. I work for a very small company myself and I care as much about customer service as I do our products.

I'm new to g bodys and I was just looking for what to check for possible issues and when I called Duane he gave me a few things to check. Like, Are the springs upside down? Are the the fingers on the top spring cup correct? Is the position of the spring end in the lower cup correct? Do your springs have the 3050F part# on them? All of these were correct, so I figured I got one of a very few sets of bad springs. Which I understand things like this can happen.

Yesterday Duane also asked for some measurements from the center of the wheel to the fender lip. Their measurements with the 1" springs installed are 14 1/2" front and 14 7/8" rear. My measurements on the front are 17" and rear is 14 7/8". So I definitely got a bad set.

They gave me 3 options:
1- Remove the whole set and return to Summit
2- Order a set of 2" springs direct from them, then return the 1" so they can test them. Probably what I should do.
3- Cut the springs I have now. I thought this was best, due to my lack of patience. UMI is about 5 days away as far as shipping goes.

I had no intention of starting an argument or offending anyone. I appreciate all of the information from people with actual experience installing springs or with UMI like yourself.
