Need help with cutting coil springs

[ksum25]

I have a 2.5-3" rancho lift on my Bronco II and bought 4" lift coils for it and was wontering if anyone cut their springs to lower it about 1.5" or so. Do I just cut of 1 winding of the spring or what? any help would be great

Um........


You don't cut springs. You go buy ones that are the right length for what you want.

I'd try an avoid cutting a coil spring.

Return or sell the 4" ones, buy the correct ones from rancho. Or try another brand.

I know thats not exactly what you wanted to hear but thats my opinion.

Someone who knows about how to "correctly" cut a coil spring will chime in soon.

generally yes. .

but ive cut, every length . ever size . you can think of,

poor man budget. cut them


remember when cut out one coil. the spring will be stiffer. you won't notice 1 coil cut.

picture this 40' -1/2" bar. it will flex , right. more coils softer

picture 4' -1/2 bar pretty stiff , right. less coils stiffer


Dont cut to much you can't, put it back. again 1 coil very little difference

after that 1/2 coil at a time.


IF you f--k up and there to short ,you can still put in a spacer

To get you height right .some times it will take 2-3 tries in vech. and roll back and fourth once on the ground. to get it to sit right.

To cut. 7" circular saw. with metal cut off blade. real easy.



IVE done countless spring swaps.


I mix brands . models. to get the spring rate. and configuration. I won't

IE.
Dodge one ton. front springs. into my 72 torino 429. cut 2-3 coil out.

volvo wagon , rear springs into , mazda 323.


there other way to, by collapsing the bottom spring. later

Don't cut it. Buy new that fit.

If you can return then, do so.

[disciplerocks]

You can cut progressive coils, not stock ones. Keep you and your passengers safe, do it right.

i cut exactly one coil off of my 4" springs and have been driving on them for the last 2 years, no problems yet. i cut them with a 4-1/2" cut off wheel on a body grinder. after i cut off the top coil, i used a grinding wheel and put a little bit of a flat on the end of that last coil to make it fit the coil bucket.

dont be afraid to cut them if thats what you need to do. it will make the spring stiffer, but not unbearable (certainly not worse than the guys running f150 coils up front) and its not gonna make your truck suddenly run off the road and flip over and explode like some people would like you to believe. some spring manufacturers will even tell you to cut off 1/4 of a coil at a time to fine tune your suspension....

here read this, its directed toward lowering cars, but its still coil springs.

A spring . Is so simple

[ksum25]

Thanks for the help guys. Returning the springs was not a option. I ended up cutting one coil off and it is perfect.

Ive cut springs on several applications over a long time never had a problem.How I figure the height is measure the span between the coils while loaded and make a whole plus fraction in the number of turns.

When I got new springs for my B2 they settled about an inch you might be a little lower later if they were new.
