Help cutting Moroso trick springs please

Check the upper (frame) pocket. If like 64-7 A bodies, it is formed for the tangential spring end and the tail has to fit to the end of the pocket. This limits how much you can cut off the coils, because the bottom (A frame) pocket also wants the end of the coil in a specific place--between the two indicator holes. Generally, you are best with an integral number of coils plus 2 to 2.5" more on one end. It might be too much, but on my A body, Moog 5230 with 3/8 coil cut from each end works.

Thanks.

Mine has a coil seat with a stop on the bottom, but the top pocket is flat all the way around. Does not make a difference on the top. So, we cut on the top of the spring.

Big question is still how much to cut?

thanks all,

Ken

If the top perch is flat and not formed for a spring end, then you should start with the 68-72 style spring that has a square or flattened top end. It is tough to give a recommendation because front end weight, desired ride height, and spring rate all affect the needed spring height. For a 250 lb/in coil you will probably want it 17-18" free length.

Ken,

you will not what to hear this In some cases I have pulled and cut as many as four times before sneaking up on what I wanted.

There is just no way to know, it is cut and check deal. I would begin with cutting 1/2 coil and put it back together. I does not matter which end you cut as far as spring performance goes. Cut the end that will best fit the spring seat after it is cut.

Ken,

Start by cutting a 1/2 to 3/4 's of a coil off, as Larry said .... Don't use a torch, try a sawsall , much neater & less heat... They are much easier to replace with the engine in the car ??? Good Luck & e-mail me if you have anymore questions .......

The last time I did a set......in a '69 Nova 350 stocker.....I had to do them twice to get the ride height I wanted. I think I wound up cutting more than one coil off.......It is not hard if you have a decent spring compressor......the single bolt with 2 pivoting j-hooks works well. It drops out thru the shock hole after you get the spring installed and the ball joint nut on......I am sure they are still sold and easy to find....

Google KD Tools KDT3450 spring compressor, you will find an example of the compressor Rich described. It is not a bad job and you get better with each R & R
