Charged RTX Both sleds do not have picks, if you want a good top end with these sleds, you have to run the tracks real loose. I would say 2-2 1/2" of gap between sliders and track. Thats just sag when lifting the sled.Not advised if runing picks.The 03 has aaen roller 54-46 helix and Freddies filters.It also has the stock cone track`it is one of the best tracks for the railbed riding we do.I know a lot riders will disagree about the track.ok i have said enough about the 03 afterall this is the Apex site.The 06 gt is the best sled for all around riding i have ever had THATS WHAT I'M TALKING ABOUT...
