I just finished my 1973 Rupp Nitro 295 I hope to post pictures soon. I was wondering has anyone installed a newer rear Track or suspension on this model. I have a track that is okay but not ideal,I want to ride this sled this winter I have 2 other sleds to ride but I think pulling up with this 73 Nitro will surprise and excite anyone who sees it. Thanks for any response Gary
wow that is what i want to do with mine the suspension looks great can you share the spec: what type of sled the suspension came out of etc. what had to be changed front drives,what type of mod.Thanks for any help.
This is a simple swap. I use Polaris suspensions, only because i'm more familiar with them. Any track/suspension will work as long as tread on track is 3/4" or less. Mark center of axle between drivers then have machine shop turn off the Rupp driver hubs. Get a pair of 8 tooth drivers(I use John Deere because they go on a round shaft and pin just like the newer Rupp drivers) have center drilled out to fit the Rupp axle. Slide drivers on axle and lay in track so drivers are where they belong. Make sure mark on axle is centered between drivers then mark holes for pins. Drill holes then pin drivers. Your done. Reinstall everything. If your not sure where to bolt suspension at just find a sled like the suspension came out of and measure from center of axle to center of suspension holes. Then from top of tunnel to center of holes. Transfer measurements to Rupp tunnel-drill new holes if necessary and bolt it in. Make sure to use a steel mounting plate, make one if you have to or the holes will egg out. Sometimes you get lucky like I did with my 73 Nitro. The suspension fit right into the same holes as the Rupp suspension. Once you do this you won't ever want to ride one with the old suspension in it. Don't believe me just ask Rooney!!

pathfinder: Anyone have a source for the correct track clips for the 72-73 Nitro tracks? Also what type of clip tool works, I've tried several and they all don't get the clip tight enough! Thanks

BeatUpRupp: Just found a '72 Nitro 340 hanging out near a relative's house. They claim it has an "experimental" engine in it and it was very fast. Even though it has sat outside for 20 years they won't sell it!!

snosnake: Hey ruppgreenhorn I would say your just going to have to check it out. Thats a fix you can not do over the internet. Just start with the easy things first like the tank pick-up.
