Hi, I want to lower the front end of my '62 is it feasible to cut one coil off the front springs to do so as it is on GM cars. If anyone has done this it would be great to hear from you.
Thanks

I've been wanting to do the same to my '63. I haven't gotten around to it yet, but here's the info I'll rely on when I do.

https://www.eatondetroitspring.com/cutting-coil-springs/

The only coil springs that can be safely cut are coil springs with tangential ends.

The problem is, with the springs still in the car I can't tell for sure which type of ends they have, and I can't tell from the pics in the manual. I'm sure John or Dave will be along soon to let us know.

Be sure to take some measurements and before and after pics if/when you do it. Good luck!

Not sure on a 61, but that's how I lowered the front on both my 58 and 65 with no ill effects to either car. I actually ended up cutting more than one coil, since that didn't drop them enough for me.

Cheers

The ends are easy to prove. Look at the bottom of your lower 'A' arm. Squarebird springs have an open 'end' which nests in a pocket. They only go in one way. The tops are flat, for that rubber piece.

So, look. Surrounding the shock, is the spring perch. If it is totally flat, so is the spring. If it is formed to the coil end you will know immediately. - Dave

I've had as many as three coils cut from the front of mine and I recommend not cutting any more than one. One give a mild rake and does not adversely affect ride quality.

The front springs on these are a bear and will destroy many spring compressors and possibly kill you while they are at it. Buy an OTC 7045B coil spring compressor, or similar.

Here is the underneath view of my mount. It looks formed to a tangential end to me.

Additionally, I found this in the manual, which seems to confirm that the bottom end is tangential and can therefore be cut.

Thanks to all, very informative replies. Will let you know how it turns out.

Hi finally starting to remove front coils of my 62 to cut one coil to lower it but noticing when it's on the hoist that the top A arm bottoms out on the frame and even if I disconnect the sway bar and upper ball joint the top A arm won't go any further. Am I missing something here? Any help is appreciated.
Thanks
Gas

The A arm stays on the car. You have to have a very good internal spring compressor to squeeze the spring enough so that it can be removed. What type compressor do you have?

Hi, I had a friend come over today with his spring compressor but it's the claw type and can hardly fit through the top shock opening, too difficult to work with. He suggested making one with 1/2" threaded bar and a couple of plates.

Yeah, external claw type will never get the job done on the springs, if the Bulletbird is anything like the 65 I did anyway.

You need the internal coil spring style tool. I went a did the free tool rental deal from Autozone and it made quick work of it for me.

Take care - if a spring gets loose it can kill, main and wreck stuff big-time!

Regular spring compressors aren't up to it.

I tried that route and ruined the tool.

Hmm, maybe my local store had a better tool than most carry?

I have to say, I've done alot of cars over the years and the springs in the 65 are without a doubt the longest I have ever seen in an uncompressed state.

Obviously. You must have a good store manager there who has multiple compressors for different types of cars. The one I use for my 2005 Mustang would never work on my 1964 TBird.

When I took my new '64 springs to the shop to install them the mechanics were in disbelief. The compressors that they had were useless for this application. So we borrowed one from the local O's, and ruined it. So I did some research, found the OTC tool online and ordered it. A dangerous, difficult job then became surprisingly easy. You know what they say about the right tool...

Thanks guys for your suggestions, I live in Ontario Canada and a local parts stow can order the OTC 7045B but it's $350 cananadian but there is an auto zone in Ogdensburg NY about 45min away,I will check to see if they would loan that compressor.
Will let you know how it turns out.

Sorry for the slow reply but I did all the suspension work. I found the correct spring compressor an old mechanic friend of mine has had it for 40 yrs, lucky me, and I cut off 1 1/4 coil off and that dropped the front end about 2" which brought the front fender just about even with the tire. Then I installed some lowering blocks for the rear springs and now the cars altitude is where I want it. Thanks again for all the input.
