Ummm yes, you can tell the difference. Add a clutch to it and look out. Last night I was cruising about 30mph on a snow covered dirt road. I nailed the throttle and the ski's came off the ground about 8 inches. Yes you can feel the pull from this kit. Check some of my posts in here, I was very, super disapointed with this sled when I bought it last year and now I can't stay off it. Maybe foolish isnt the right word to use, I'll go change it.
