Just put a 3"x162 on last saturday, there's a 1/4" of clearance on the front of the tunnel. tested it this weekend on 20" of fresh total snow was 87" at 6500 feet, snow was soft you sunk to your waist when you stepped off your sled western MT. first thing I noticed was taking a corner the edge of the track would catch and tilt the sled on it's side unless you stayed on the gas around the corner. the old power claw would slide around the corner, the 3" would sort of snag. some specs on my sled. I'm running a Twisted 09 m8 162 with Kmod conversion at 10 PSI about 240-250HP. this track is huge. my buddies told me as soon as the turbo spools when I punched it this track would shoot a wall of snow out the back. I felt that I had less track speed. you could hear a whirl of wind when you hit the gas. this track really chews up the snow. the braking was awesome, you could stop on a steep downhill, no problem. comparison on a steep climb my trench was about 8" deeper than my buddies on a 2.5" camo xtreme. but the guys behind on the trail would say that I was throwing out softball sized chunks of snow behind me. track wanted to eat my mudflap also, had to rig it out of the way with wire, but overall I'm pretty happy with the track without the Kmod this thing would want to flip over backwards. My Kmod was set at 4(90%) coupled all day and the front was still 2 ' in the air. the skis never touched the ground on a climb
