I am looking to put a 136" track extension on my 2002 440x and wanted to see who else has done this. The 2002 440x came with a SC3 skid and I'm trying to clarify the correct rail extensions to buy from Tracksusa.com. The 2000-2002 rail extensions on TracksUSA are for trail sleds, which did not...

So I am picking up a 2002 440x this weekend that I used to own a few years back. I am buying it with the intentions to have a project build and turn it into a powder machine. One of the main upgrades I want to do is turn it into a 136" skid. I found a used 2002 Renegade 136" skid for sale for...

These originally came off an '07 440 Mxzx. Have been re-valved for aggressive trail use, basically valving is similar to a new X-rs. Shocks are remote reservoir with high and low speed compression adjustments. Shocks are 18" eye to eye, will fit both Rev & XP chassis; I had them on an '09 Tnt...
