Front coil springs too low
 

I put a square body front crossmember under my 65 and I can't remember if I used the original 65 coils or the ones I got with the square body front crossmember I bought from a guy. Maybe it had drop coils in it and he didn't tell me, who knows. The other day was a momentous occasion when we dropped the v8 and auto trans into the truck. I should add it has no hood on and no front bumper on yet. First thing I thought was geez it looks pretty low. I can't even get my low profile floor jack under the crossmember. Upon closer inspection I see the suspension is sitting down just touching the snubbers. So my plan is new coil springs from a square body. I see I have the option of regular or hd for a/c trucks. The specs for each show the same uncompressed and compressed height but the hd springs have a heavier rating and thicker diameter rod. I'll add my sbc v8 has iron block and aluminum heads and no a/c. What have others used??

Just get stock coils for your truck year. Show some pictures also, so we give you the right advice

The more I think about it I think I used the springs that came with the square body front crossmember. I wonder if the guy I got it from used drop springs or cut coils off the stock springs. I'll know more when I swap them for new ones.

Right now I can barely walk around in my cramped space let alone take decent pics. Can't wait till I can put some on here though.

Here's a short thread about what happened to me when I used a square body crossmember with stock height springs for a '66. I still don't know where the drop came from. http://67-72chevytrucks.com/vboard/s...d.php?t=586664 After all that, I ended up dropping the rear a total of 3 inches (2" drop springs and a 1" block) to achieve a slight rake.
Edit: FYI... Early Classic says square body springs have a stiffer rate than earlier coils because the trucks are heavier.

I never swapped the cross members in my trucks, so I don't have these problems.
If I can remember back 20 years ago. I believe the square body springs were 1" shorter. Not 100% sure of this.

I don't know if this helps or not but I swapped in a complete front suspension from a 73. I bought CPP 2 1/2" drop spindles & Moog stock height & rate springs for a 73 C-10 with a 350 and A/C.

The last pic is how the truck sits after the work was done. I still want to drop the front another 1" - the rear is bagged with 45 psi of air in them.

Thanks 64shortbox. I ordered the same springs for a v8 a/c truck. I have 3” drop spindles on mine. When I get these ones out I’ll put them side by side for comparison.

Re: Front coil springs too low
 

Yup, the guy I got the squarebody front suspension from had trimmed 1 1/2 coils off. I'll see where the truck sits as soon as they are in.

Re: Front coil springs too low
 

1.5 coils would be about 3” drop.

Re: Front coil springs too low
 

Well it's up about 5". This height is with no hood, bumper, grill or fluids. I'll wait till I'm all done to reassess to see if I need to trim some off the coils.

After a couple weeks or so it will settle a little bit too

Re: Front coil springs too low
 

If you jouns the front end a few times. It should settle to its ride height. It shouldn't change at all after that.
