Determining Torsion springs

[Northern]

I have a 2008 Nytro RTX with a 144 kit installed.

I am working on getting the sag out of it.

I understand there are heavy duty torsion springs available from Yamaha.

How can I tell if the sled already has them?

If appears that the part number might be stamped on the short arm but I cannot see it under the sled.

Were the two a different diameter of spring? If so, can you provide the diameter so I can measure them?

you can mic them the thickness of the spring is how Travis told me to check mine. Of course I no longer know what the specs were. Call BOP Travis will know. and he will prolly have a great deal on the new/used ones too

someone might answer faster but i can check my stock springs for my apex xtx as i ended up with nitro xtx springs on mine as stock was too heavy for me.

I emailed Travis back to see if he knows the difference. He was looking for 2100's for my sled. I am wondering if I already have 2100's thought.

I spoke with my local dealer today and they could not tell me a way to figure out the difference.

Thanks, but RTX and XTX use different springs and I was told they do not interchange.

If there is sag I would guess that you don't have the 2100's. 2100's are really heavy springs. I just ordered a couple for my sled because I had 4-5" of sag with out any weight on the sled and I rider pretty hard to they will be better for my riding style. I have a 08 nytro MTX 153 so not much longer then yours.

Here is what Travis has to say.


"Typically the material will be thicker or there will be less coils. I've attached a photo of the 1900 Spring for you to compare yours too. If yours has more coils than this photo then you have softer option below 1900 which I believe is 1500. When referring to photo I refer to it as 7 coils. The 1500 has 8 coils. Let's make sure you don't have the soft 8 coil spring first. I can get wire thickness of 1900 spring once back in shop next week. "
