Large diameter left rear spring?

[Krooser]

Watching a video featuring a new Warrior chassis... looked like a pretty large diameter left rear spring on the car?

progressive deal i would guess

[fastford]

swift calls it a tornado spring , it allows a soft rate without coil binding....it basically took the place of a stacked spring and is better IMO.....

2.5-5.0 spring soft like 50# to circumvent deck height rules

[CCHIEF]

I've tested with an 18", xx# so far, allows you to get your deck up ~12+" from static to dynamic. I don't believe it is compressed enough to nest the coils at ride height, or even compressed some below static ride height. Best application is when rules limit one spring per wheel.

If you take away any more correct or linear spring rate changes due to added diameter and less bowing:

If you are limited to a single spring and maybe a length rule, this is where is comes into play. Say you are limited to a single spring and a 16" max length rule

Your ride load is say 600# @ 18" and you extended number is at 23"

Say you put a normal 16" 50# spring on the car, it coil binds at say 6" tall so you have 10" of travel before bind. The spring will be coil bound before you get to you 600# ride hieght load. At 500# you would be coil bound before you got to you ride number.

If you used a V spring like swifts, say that same spring 16" 50# V spring coil binds at 3" (coils go inside each other to allow more travel before bind) so you have 13" of travel. 50# x 13 = 650 so you can get to ride hieght and not be coil bound.

I just made up those numbers, above.

Remember spring rate is spring rate, so unless you doing a progressive or digressive stack where the rate is changing during travel, the V spring is no different then a single standard spring or a stack with no stop nut besides it allows more travel before bind (if you exclude any minute changes to rate from the spring bow issues).

Its almost hard to fathom that they're getting 12.4 inches of usable stroke in a 16" spring!

[dirtracerl77]

I want to know how they are getting that much stroke from 9 inch stroke shock.

Just because the rear of the deck is up 12.4 inches, does not mean the spring or shock traveled that far.

[fastford]

im not gone start telling numbers , but the swift spring were on is not coil bound at ride height and it is softer than any stacked combo we have ran ........

[RaceEngineer]

A true conical spring could go to the height of 2 wire diameters, if a guy thought he needed that. Any spring mfg worth a lick can make you some, for a price...

[fastford]

i think it was well worth the 89 bucks , but as with any thing , it aint no magic bean , if you like it and tune with it and like the effect you get and the clock says you picked up , then its for you.....

That phrase "usable stroke" is from Swifts website.....that's a weird phrase to use when discussing a springs usable length without coil bind.

[grt74]

forgot about the swift deal, good if you need to beat the rules, seen them at pri, no big deal just beats the rules, if i can use the stack its more tunable, but there are times we kill them with a standard spring and we fall on the ground laughing, super soft is no always the best, they do it to beat the body rules is the only reason, put a 300 on the lr then when it gets slick run the nut down and preload 1-2 turns, i think most would love it but then the deck is too high, to the so called rules

[grt74]

Where on the site would a guy find these?

don't think there on there, will have to call them, they have a few different ones,3-4 i believe

[RaceEngineer]

Nevermind, I found them. That 50#/in isn't good for 700#. Won't work for me.

RE Suspension is where I got mine.

My ex was stacked

[ZERO25]

My ex was stacked

Obviously, you WEREN'T! :)

[fastford]

OMG Z25 , you caused me to have to clean my key board , now dont be picking on krooser , he!! , he may have been over stacked and is why she left...lol.....

Are you saying Krooser was TOO soft?

Don't they have medication for that? :)

[95shaw]

Maybe he was just struggling for traction? lol

[JLyons]

All that power and no skill to “lay it down” 😂

i aint saying jack sh!t , i like krooser and was trying to help him save a little face.....but he will have to answer your question , we better behave though or ole SCD might tell on us for acting like this in the sacred tech section.....lol......

[Krooser]

Thanks for coming to my defense... I think!!!

[MasterSbilt_Racer]

Can't you all leave poor Krooser alone?
