progressive spring on rf

[erm11]

Thoughts.............?

Very vague. Of course it could work. But the word progressive tells a person a lot less than the word linear. A curve for something that is progressive could be drawn any number of ways.

Coil bound springs are progressive near bind. Bump stops are progressive.

ed,

are you wanting to put a pull bar spring on the RF?

[erm11]

I had thoughts of it, but after running one on my spring rate tester realized I would be at like 800lb at static ride ht with a 600/1200 progressive spring.

You can make a dual rate setup for stock front ends. There are plenty of short springs available to make any combination.

Is that legal?

Depends.......I just painted everything flat black to keep the boogeyman from looking! lol

Check out draco I know they have a progressive spring designed for the rf. Teo has them for sale on their website. Alot of northeast modified guys in my area are running them

Not consistent enough for most to run. Lots of shock tuning involved as well. Keep it simple. Dual stage or one linear single spring. Now if talking bumps then stack em up and slow the progressive rate down and make it controllable.

I'd like some info on how to do a dual spring on the rf

[JustAddDirt]

Pretty simple really.
2 3.5-4" springs with both ends flat.
you have to machine a collar between the 2 springs to connect them square.
in lower a arm depending on the type of lower seat used, you must make a piece to make the lower a arm mounting flat, instead of the spiral seat for the cut off spring end.
Toughest thing is finding the short springs in stock somewhere.

There is a set up for the front end dual stage and not noticeable for sale. Someone I know is running it. You can change when you lock out one of the springs by turning an Allen head bolt. He's bad fast on the dry but tacky hit or miss with it.

dual stage for a mod front end with conventional springs??

Pretty simple, Just like JAD posted. I ran 1, about 5 years ago on a Pierce.

[Mr.Kennedy777]

That's a stacked spring though which is basically a progressive spring made from two different springs, dual stage requires a lock out either you're on just one or both. How would you lock out those conventional springs and secondly rules say one coil spring per corner for IMCA don't they. Not too familiar with wissota mod rules I hear they're very similar
