View Full Version : Placement of cut coil springs

OK,

Have a question. I cut my stock SB springs and before I cut them the top and the bottom had both had flattened out coils. But now that I cut the springs(removed one full coil) I have one end that is not flat anymore. The bottom is still flat because I cut only from the top. So my question is which end should go up into the spring perch in the frame and which end should go in the lower tubular control arm? Thanks In advance!!

One coil may be too much but need to put the round end at the bottom as it will fit the A arm cradle better now... I normally go 1/2 coil at time. You have now changed the spring rate and hope you used a cut off tool.

Hello,

Yes I used a cut off wheel to cut the coil. Also when you say to use the round end in the lower control arm are you talking about the part I cut or the flat area that was not cut? If you mean the part I cut then I would have to turn the spring upside down??

Thanks

The flat end should go up into the perch.

There is a hole in the frame rail to view the end of the coil. Place coil in perch, view the end of the wire or coil in the hole, regardless of where the bottom coil end lays in the lower control arm pocket.

I personally have a hard time buying the above physical install, but, the experts here say it is correct. I use the lower control arm pocket to reference the spring and let the top of the coil sit where it may. But, apparently, its incorrect.

What do you do with stock springs? I have tried to line mine up in the lower control arm, but the top doesn't sit right in the frame. What do you use as a reference - the top, or the bottom?

The top of the spring in the frame rail, sets in a cup. There is a hole to view the end of the coil at the top.

Align the upper end of the spring with the hole, and the bottom will land in the lower control arm as it sets.

Just make sure the spring is in the cup, you can view the end of the spring thru the hole, and the bottom of the coil spring rests in the lca pocket, regardless if the end of the spring is at the end of pocket.

Thanks.... I have GW UPPER TUBULAR CONTROL ARMS and bought a set of lower tubulars as well from GW(VIA JEGS). The nice thing about the lower tubulars is that they come with a rubber type spring holder that moves in any direction I want so I guess the most logical thing to do is line up the spring in the frame perch using the flat part of the spring and then move the spring holder thing in the GW lower to line up with the end of the coil. Does this sound right? And again thanks for the info.

Then you cut at wrong end but dont think it matters at this point unless you have so much curve in the spring that happened over time where it hits any part of frame? I do believe that at any point if the spring is not up against the little grove stop in the lower control arm,, over time it will rotate and slip into it. You will know it if you are on top of the bump as one side will set higher than other... Flat should have been at top in my opinion. You basically cut off one whole coil so you should be back to where you were on spring clocking but shorter now.
