extending iq 600 121 to a 144

[sledhelp]

I have a 2009 polaris iq 600 121" with 160 miles on it (yes 160), last year I went on a Wyoming trip with my 09 switchback 136 and had a blast, but i would like to be able to bring one more person with me and I would prefer a 144 over a 136. I know where to buy the extensions and track, but a couple other questions.

1. does the suspension still act normal with an extension that long or does it start to act funny?

2. If i land hard on my back end will it do anyting to the extension or suspension?

3. will I need to change the clutching or the gearing?

Any reason not to use factory rails and suspension for a 155"?

That would be a bit more expensive, fairly hard to find, I do not want to go that long, and I don't want to mess with placing the new suspension in the correct place and have to drill new holes. The extensions are just much simpler. A new suspension is not in the question.

the 155 skid will bolt into the same holes as a 121

I had a 07 600 155 I put a 162 x 2.5 camoplast under. I loved the sled. Geared it low worked great.

That all sounds good but has anyone had any experience extending the track that far?

I have a 155 suspension from a 09 rmk for sale and you can usually find 155 tracks pretty cheap.

i am sorry, i do not want a 155. I want to extend my 121 to a 144.
