Just got the tracks usa package deal for $489. Any tricks to instalation and how do you like and how has track/extensions held up.

the extensions are nicely made, though i had to grind on them just a little bit to get them in nicely... had to round off the corners a bit... just take your time and do it slowly... it's not hard, just time consuming... my first suggestion would be to do the track and skid first, then do the tunnel

I've done a couple with the TracksUsa extensions. There's a raised section on the extension that fits into the window on the rails that used to be occupied by the rear axle. It's a pretty snug fit as I'm sure they are picking up a bunch of strength/rigidity with the close tolerances there. I've had to get a file out and dress the ID of that window on every install so far. Not a big deal, but probably the only thing that requires much in the way of patience. The rest of it just bolts together.

I've never heard or seen a complaint, of any kind, regarding ANY issues using those extensions.

Yup, had to do a little bit of grinding in the back of the rails to make the extensions fit but they are worth it. Definitely would buy their kit again.

Will I need a longer snowflap?

your stock one is fine. thats all i use

If you want some pics of my installation email me.

Sent you a pm, would love to see pics.

Here's mine. By the way, this is for sale as a roller. With reverse. As is or with 121". Making room for Edge tripple conversion.

The rail may not excactly mach the ext. I used a belt sander to trim the rails a bit, just take your time, the ext. are cnc'd the rails a stamped so they are not all excactly the same. I dont have any close up pics, but if you need one let me know

I am putting on extenstions right now. If you want pictures let me know. Right now I have everything apart and just put the extensions on the rails.

Please post pics......thanks.

Here are a couple I took today. Let me know if you need more or close-ups.
