More than likely they are stretching for light.

Sago "palms", Cycas revoluta, are outdoor plants not houseplants, give them plenty of sun during warm weather - they must only be indoors in the winter otherwise they will slowly decline, unless you have a spot that receives several hours of direct sun.

Some general info here

Mine is in the middle of a room that has a southern facing window and a north facing window along with mirrors that reflect the light. If I could get my camera to work I'd post a picture. My south facing windows allow me to grow (just about) anything.

Its from a lack of sunlight. The same thing happens to many other plants grown inside but cycads are very noticeable.

you may think that there is enough light but it is not even close. unless the windows are from floor to ceiling and wide as well, growing a plant next to a window is the same as having it grow outside in a cave. a southern window this time of year is useless because the angle of the sun is high so most of the direct sunlight does not reach the plant. south is great in winter, east or west are better in summer. a light meter would verify this. a shade plant may tolerate it, but not a plant that needs sun.

do you have space outdoors?

I have vast space outdoors. I moved it out there this morning. Now it will have about 12 hours of sunlight (directly) is this too much? So if I'm hearing (reading) you right, my plant will thrive or at least survive in winters in my home with the south facing windows? What is the lowest temp it can tolerate? I was thinking about planting it outside with some other palms for the summer and then digging it and bringing it back in in the fall. Which it really doesn't get to even 40 degrees here until the beginning of November. Love to hear your suggestions!

First of all, putting the plant right out into sun is risky, most likely the newest leaves will burn, they are not used to it since they matured while indoors, your best bet is to take the plant out a little longer each day for about 10 days, but even then the new leaves may still burn. If you get a new flush this year, the leaves will be normal.

Second, Sagos will do perfectly fine indoors in the winter with minimal light, just make sure you water much less. Healthy plants will tolerate temps into the teens, but plants in pots are not as cold hardy as in the ground. Digging it out each fall is not practical and would become more and more difficult as the plant grows, you should keep it in its container.

Thirs, and most importantly, based on your questions, you really should do a lot more reading about how to properly take care of cycads. Here are some links to get you started, in no particular order:
