I have an 06 Apex GT and I want to install a 1.5 inch lug track. I was told that it will hit the tunnel protectors Has anyone had this problem and if so did you remove the tunnel protectors, is it ok to remove them? The reason I ask is Because i'm not sure if it weakens the tunnel if you remove them. Any help or suggestions would be greatly appreciated
I am installing a 136 extension kit and putting on a 136 x 15 x 1.5 inch track

Jody,
I have the exact same set up. It will hit your protectors when it balloons but it wont hurt anything. I have 1000 miles on mine with this track and it has had no problems.

Just wondering if anyone has removed the tunnel protectors from an Apex GT is it a big job? do you have to remove the exhaust to get at the rivets to drill them out?

You do not have to remove the exhaust, but you do have to remove the seat, gas tank, etc.

Tunnel protectors are not a structural part of the tunnel.

You don't have to remove anything. When everything is out of the tunnel for the track swap, you can remove them from the underside. Removal from the top is only if you insist on drilling the rivets from the head. No problem grinding them from the end.

I would be more worried about the track hitting the attatchment points for the tunnel protectors. I'm not able to see my sled right now, but I'm pretty sure there are small "bumps" that they attatch to. IMO, I would think that the track would get chewed up those worse.
I would think there would have to be a different way to make this work. Maybe something like installing a thinner set of tunnel protectors? I have somebody make some if you're worried, but if the other guys say it works fine as is, I would try it first.
Does anybody see any red flags with just mounting the rear suspension about 1/4 to 1/2" lower in the tunnel as long as both front and rear points are moved? I don't know......

Why would you want to slow your sled down with a deeper track anyway????? Just curious.

When you remove the tunnel protectors you remove the "hangers" that they hang from also. There is nothing hanging down in the tunnel when you remove them.

Some people are more concerned about Traction and off trail more than top end :ORCnate007 said:

I'm looking for deeper lug for traction in the deeper snow. Will the suspension collapse enough into the tunnel that it will hit up underneither the exhaust? Has anyone removed the tunnel protectors and bottomed out rubbing against the underside of the ehaust or ripping at the top of the tunnel? Any suggestions or ideas would be great
Is the Apex mountain opened up underneith with the tunnel protectors removed?
Thanks for any help JODY

I've been running my Nytro for 700 miles now. It has been stretched to 136" with a 1.5" lug.
I removed the tunnel protectors for two reasons - clearance for the track (which really wasn't an issue anyway) ... and because those tunnel protectors collect a lot of snow an ice. Before you know it those things are hauling around 20lbs of ice!
I removed the protectors, and the little mounting brackets. I have had abosolutely no problems. And I run my track really, really loose (I've got extro-drivers) and the track has not even balloned to the point where it hits the exhaust.

I ran a 2" track with 8 tooth driveron on a stretched out vector which is the same tunel and never had a problem.I have bottomed out numerous times.
