Just checking again for the correct part number for the 800 proclimb 153. Is 9174 the right one?i saw before that there was a different number, just want to make sure.
9174 is an 80 duro track. The "stiffer" track is the old style camo extreme, which is not a single ply track. Both work very well. The direct bolt in for the proclimb or m 153 is the 9174.
I don't believe the "old style" is available in a 2.5" anymore. I had one on my wife's M8, a 156 x 2.5", used an offset axle and 9" wheels to gain some track adjustment. Also had to install new track clips and trim the outer "nubs" to clear the diamond drive. I used a 9175 (162" CE) on my M1000 - the track works very well. You may be thinking of the 2.5 "peak" track, which isn't very durable from what I've seen. I'm not sure if it is 2.86 or 3 pitch though. I would suggest that you speak to whomever you are buying it from, they should be able to answer your questions. If you are talking about the 3" track, you will need smaller drivers, and unless the sled is boosted, track speed will suffer significantly. I personally don't ditch ride, but I certainly wouldn't with a 3" track.
