Stacked Springs

[CHUMBA]

I have tried that the 4" is going to coilbind before i get the travel needed, iam using the 5" afco spring now and its close to coilbind, I want to go softer up there, thats why I want to run 6 or 7" spring. running integra shocks nut goes on first then spring then devider then next spring then then cone, thats the part I need about 1 1/2 to 2" of spring compress to get on. the bottom spring is 8". any thoughts anyone???

8" bottom spring...4" top...12 inches total...

What rate are you trying to produce?
What lengths/rates are you using?
Your short spring is probably too soft.

[CHUMBA]

What rate are most people running? (the combinded of the two springed) 200 to 250 or 250 to 300 or more or less? Iam in the 250 to 300 range. Thanks!

If you are after a 200+ #/ inch spring , I see no reason to stack.
If less than 200, then there is a reason to.
The example above to get a 133# / inch should suit you well.
4" 400 and 8" inch 200=133#/inch 12 " spring.

jedclampit: this is for a right front app. were thinking 300 top and 700 bottom with stop nut.

That 300 is your problem. You are probably going to need a 6 or 7 inch spring. Good luck finding one.

yes i know thats why I was looking for spring compresser, and also wondering, what two springs most were useing? and if Iam way off on what Iam wanting to try. Thanks for replys CHUMBA.

I have run 400 on top of 400 and it was loose coming of thats why I thought about going stifer on bottom, the tracks I run on bad slick!! I have played with adj on stop nut, but still loose off.

Well then just stiffen the bottom.

[CHUMBA]

We have but the more I stiffin the bottom the closer the top 400 5" spring is getting to coil bind, if I go to a 6" long spring I cant get the bottom cone on. Thats why I was asking about spring compresser. anyone know of anyone making one? or a way to get the spring compressed to get cone on? Thanks again for all replys.

chumba,use two 7in springs,you may have to work a little to get them on but they will go on by hand,we use hypercoil springs on ohlins shocks or a 7 and a 5 or 6 and a 4in spring i would not worry about the coil bind because it should hit the lock nut before coil bind if adjusted right but you can always check it on a shock/spring rater before putting it on the car

[CHUMBA]

grt74 you got PM

600 4 inch top
500 8 inch bottom
