New Springs - High In The Front

I just recently replaced my front springs with the stock height UMI units. The front end now sits really high (both springs are properly seated - I made sure of that). I have about 2 7/8" between the top of the tire and the fender lip on each side. I am going to be replacing the rear springs soon - also with the stock height units.

UMI suggested the new rear springs, along with cutting the front coils. I am not questioning them at all with this post. What I am wanting to know is if anyone has done something similar to their Chevelle. If so, did you cut just a quarter coil or a half coil?? My old springs were about 3/4" shorter than the UMI units. I will post pictures of just after the spring change and then with my air shocks pumped up (the first three pictures are just after installing the springs - the last four are after airing up the shocks.) I have about 200-300 miles on the springs now, so I don't know if they will settle down some or not.

I want to get the nose of the car down. If anyone can guide me in this, I would greatly appreciate it. Thanks in advance.

Re: New Springs - High In The Front

I have this same issue

UMI Stock height springs.

"You can cut them" was the answer I was given

People say KOOL you did big block front springs like on the day.

I also have the UMI shocks

$800+ investment and it's trial and error. GTFO

Not umi but when I rebuilt the front end on my 68 El Camino and my 66 chevelle my front end went way up in the air. I ordered stock replacement springs. No my El Camino doesn't crush the headers when I go over curbs and have a load. Jim

Jim, did your front end ever settle down, or did it stay high??

Re: New Springs - High In The Front

I hate it when I'm always going uphill. Replace the springs with ones with the desired ride height.

Re: New Springs - High In The Front

Just had these very same springs put on my car, they replaced the 46 year old sagging ones, luckily I went with 2" drop spindles as well so the ride height didn't change a bit, just much stiffer which is good since I have an anchor for an engine, still want to go lower but I wouldn't want to cut the springs in my case because of how stiff the ride is already.

I guess you still do not get it Rob

As was explained in/to you your Thread
Lowering springs=

My Posts #s 4 / 5 / 8 gave reasons/detailed explanations etc.
plus someone's elses # 9 Post said it in plain English

" replacing worn springs that are sagging with oem replacement springs = increase in ride height.
replacing small block non-ac car springs with big block ac car springs = increase in ride height. "

plus UMI Perf Posts offering help to work it out

The kicker was not replying to the #10 Post of Philip a Admin person

Re: New Springs - High In The Front

Brian
if you look in this Thread at Post #4
Lowering springs
you will see that I was/had the same type of High Frontend with stock height old SBC springs
27" from Ground to underside of the Fender lip in the middle/center

This was after I had changed the old weak Rearend springs with new Moog # 5385 Rear Springs
26" from Ground to underside Fender lip in the middle/center

What was the measured height from the Ground to the underside of the Fender Lip
Before the Spring change ?
After/now with the new Springs ??

It also looks like you have lower profile Tires, with less sidewall,
and the Wheels look to be larger than 15" Diameter !

Re: New Springs - High In The Front

Kirk, eventually I plan on getting the UMI lower front control arms, probably the 1 inch drop model. If I were to cut half or 3/4 of a coil, how badly would that affect ride quality now and in the future (with the new control arms)?? My car is my daily driver, so I would prefer it not to be a harsh ride.

Re: New Springs - High In The Front

Brian I would think that is something you should talk to UMI Perf about as they R&D their parts with cars
all the time or have feedback with other customers etc.

With what I did to my car's frontend by installing the UMI Perf Tubular Front Control Arms
with Viking DA Shocks
and in making it ride more firmer and stable it was a big plus over the old ride & handleing of the car for me

IMHO cut the Springs a little at a time is the way to get the desired height that you are looking for
I do not think/IMHO that cutting off that little of the coil will affect the ride that much
even tho it will stiffen up the coil by making it shorter which will also give better handling
the better the shocks the better the ride IMHO

Re: New Springs - High In The Front

I did upgrade to Bilstein front shocks when I did the springs. I also just bought the parts to make a ball joint separator (using a 5/8" rod coupling and two 5/8" x 1.25" bolts), as I don't want to damage the boots on my brand new Proforged lower ball joints. If cutting 1/2 of a coil off will drop the front end about 1", then that may be what I need to do.

Re: New Springs - High In The Front

We used to cut stock springs all the time, never again. It ruins them.. Maybe UMI springs are designed to be cut..

I'd try the 2" lowered springs like the guy above..

Usually for every 1/2" of spring change, the car moves 1" due to the control arm ratio..

Re: New Springs - High In The Front

Cut them Brian...they won't take them back anyway. If not satisfied with the result, then buy the other set. As far as the ball joints go just back off the nuts and whack the control arm with a deadblow hammer...the spring does most of the work and works every time.

Re: New Springs - High In The Front

You can have the springs reset by a spring shop to your desired height. However, if the springs were wrongly made, UMI should be paying for it.
Cutting coils [ or a section of coil ] risks putting a bend in the spring & it will possibly rub on the chassis opening. Not a good idea.

Re: New Springs - High In The Front

No way in hell would I tell someone to cut their springs, especially if I worked for the company that sold them. Cutting any springs make them have a much stiffer ride. It sounds like they sent you the wrong springs.


I put BMR 2" lowering springs all the way around. Car handles like a dream now with hardly any body roll in turns. The new springs plus all new bushings front and rear and I'm satisfied.
