Powertrax No slip is what i went with after much reading and consideration. If your gonna upgrade the rear, go all the way and lock it up. I blew 2 LSD in my blazer in two trips to the mud hole before i got my taco, so i stayed away from clutches. The No Slip is barely noticible in town now and the difference in traction off road is unbelievable. I dropped my front tire into a wash out on a gravel road this weekend and was sitting on the frame. Pulled right out of it (No damage) and i KNOW that before i put the No Slip in, I would have be burning up the cell phone praying for a signal. No snow or ice where i live, just lots of rain, so i can't comment on the No Slip on ice and snow. <img src="/forums/images/graemlins/kewl.gif" alt="" /> <img src="/forums/images/graemlins/kewl.gif" alt="" />
