    2001 Indy 500 Modifications, looking for some tech help

    Good Morning All, I'm modding a 01 edge indy 500 that I have had for about 9 years. Its a good sled, I havent used it much so it doesnt have many miles, but my needs have changed and I dont trail ride anymore. I need something that has a longer track, and is geared much lower for pulling dogsleds while icefishing. So one thing at a time,

    I bought a 144 rear skid from a 06, or maybe 07 switchback, came with a 1.25" track. The guy i bought it from wasnt sure, any way to tell, or does it matter? Does anyone have one of those and can give me the distance between front and rear mounting bolts? and the distance it should be down from the tunnel in the back. Or is there a website where that information would be published? Thanks.

    Second, I fully realize that with my little 500 engine, this thing will need to be geared down significantly. It came factory with 21/40 gears and a 9 tooth driver. I ordered 19/42's for it and a 8 tooth driver for the reduction and the clearance so I can run pics. I figured this out to be a 2.2 gear ratio on the gears alone, down from a 1.9, plus the smaller driver. Does anyone have experience with going from 121 to 144 tracks, is that enough? I want it low, like old ski doo tundra low. I havent driven over 50 mph in years, most of what I do is breaking trails through the woods and ice fishing.

    I havent looked into the clutch yet, any advice on that?

    Thanks in advance.

    Check out jbshocks.com He has a bunch of great tech info on various suspension swaps. You will likely need to make or purchase drop brackets for the rear to hang from. As for the clutching, there will be others that can help better or maybe call SLP and let them know your plan and see what they say. Good luck and keep us posted.

    Okay, so jb shocks has some really good stuff, just not for my suspension. If someone has an 07 switchback or has access to service manuals or something that would give me the measurements I need, that would be great. Thanks

    I know it says RMK skid and IQR but there are some good measurements on page 3 that should get you pretty much where you need to be.

    Thats the best Ive seen so far. Should be what I need. Thanks white. It would be nice if someone maintained a database of all of those measurements.
