Aftermarket F4i springs & 919 springs are they the same?

[HeliMech]

I am looking at picking up a set of aftermarket fork springs. I have 2 sets of forks on hand 01 f4i and 02 919 at the moment.

I am wondering if the springs will work in either set of forks. I found a set of 919 springs and was hoping when i switch over to the f4i forks in the furure the springs will work in those as well.

Anyone know if they are interchangable or similar?

Thanks,
Ian

yes they are. i ordered springs or an 02 919 and dropped right into my 02 f4i forks no problem.

The spring lengths are different but the diameters are the same.
F4i springs are even softer than 919.
The same aftermarket springs are used for both, one adjusts to the fork set being used by the length of spacer.
A buffer kit is a good idea.
Traxxion sells them, not sure about other suppliers.
The buffer kits locate the springs much better, and reduce the spring rub on the ID of the tubes, less metal wears off, less oil contamination.
Buffer kit not an absolute necessity, but good to have.

Perfect. Thank you.

buffer kit came with my traxxion purchase as well.

What does the buffer kit consist of?

[Pvster]

its basically a tube that fits the inside of the springs and then the damper rods go inside the tubes and thusly held in place.

I was speaking to a great rep at traxxion. He will include both sets of spacers with my springs for no extra charge. Great customer service.
