The "66" service manual has a different method for Chevelle front spring replacement. Dimensions for a special tool are shown,and how it's used for the procedure. Wonder if anyone at the dealership's did it this way? Probably not,we always found ways to improvise to save time or if a special tool wasn't available.

I think I'm going to just go borrow the internal type. I looked online at just buying one. The cheap ones seem like a good way to end up in the ER.

Re: '66 Chevelle Front Coil Spring problem

I'm running into the same problem as you have.

I've got Moog 6200 on the front of my 64 and it looks like a gasser. The spring is so tall it's ridiculous. Being so tall makes compressing it extremely scary. My spring compressor is so tight I have to angle it so the threaded rod comes through the hole in the frame for the shock rod.

The a-arms are almost in full droop angle with full weight on the front end, a-arm bushings loose. I can't get the car aligned with it sitting like that.

I've seen the 1:2 ratio for cutting coil springs, 1" of coil for every 2 inches of suspension drop. Will be trying it soon, tired of my front tires wearing out before my rear tires.

I just don't understand how someone can buy the CORRECT part for the car and have it lift the front that far. Shouldn't have to go back and cut the springs over and over until it's to the height you want. Figuring my stock springs had sagged over the years, I was only looking to gain an inch of height in the front, not 3. And yea, mine is the same, there's no way I can get it aligned with it sitting that high.

Any they now have a lower gas shock in addition to the hydraulic socks for a better ride.

Jim, Eaton Detroit Springs are the best. I have used there springs starting back in the 80's.

Don, Where did you get your service manual. The one I bought was a chassis service manual. Same thing?

I have original "66" and "67" Chassis service manuals and Unit repair manuals(overhaul). I got them from a guy I worked with at a Chevy dealer back in the 70's. He had a garage full of them,unused,he told me that if you were a Certified Chevrolet Technician back in the 50's and 60's when the dealership got the new model year manuals each Tech got a set,he took his home.He passed away years ago,I asked his son about the manual's,he sold the whole lot to someone.Probably more info than you needed,but I thought I'd share the story.

You can chain or rope the spring such that it won't jump out and hurt you. The way that guy in the video improperly placed his jack (and with no spring retention) he is very lucky he didn't get hurt. If you place the jack correctly then by the time there is a lot of dangerous spring energy it is extremely unlikely it will jump out. I have always used cut high rate springs, which tend to be shorter, and never needed a compressor. Depending on the spring rate there will be close to an inch drop with use. Don't assume or judge height until you drive car for a while.

Good advice, Traveler. Thanks! I'm planning on working on the car again this Sunday. I'll report back what the outcome is.

Re: '66 Chevelle Front Coil Spring problem

I have a 66 Chevelle Malibu convertible that I have restored and put all new front and rear springs in it. I put front coil springs for a SBC w/o AC. I had the same problem in that the front end was too high. I was told by several people to drive it for awhile and let it settle. I drove it for about 3 months and sure enough it settled down very good. The front is about 1 inch higher that it was but it looks great. Hope this helps you out.

Re: '66 Chevelle Front Coil Spring problem

So here's some really technical math for you guys lol...cut 3/4 coil off of a SBC w/no A/C spring = 1-1/4" drop. It's still a little (3/4") high for my taste but, collector doesn't drag, wheels don't rub so I'm happy. Hoping for a little settling...maybe 3/4" or so. The second spring was a lot easier than the first as I learned what not to do on the first. Went ahead and replaced the shocks and stabilizer bar bushings while I was in there. Shocks were garbage, bushings were hard and had some splits. Got to drive her for a little bit yesterday. Nothing like driving a Chevelle with the windows down on a spring day. Thank you guys for all of your help.

Re: '66 Chevelle Front Coil Spring problem

if you add spacers at the rear or change the rear spring, that will drop the nose.

I've got coil-overs on the back. I plan on raising the back up a little.
