My brother got a 99 700 SKS with a 136x1.25" track on it. It might be a 1.5", but I didn't measure. The track rubs like crazy, looks like at the back of the tunnel, well before you should be bottoming out. Looking at the rear skid, Xtra-10, nothing looks out of place. The RRSS is not taken out like some do, it is on high, in the front hole IIRC. There is a lower mounting hole on the mounting bracket for the rear torque arm. I'm thinking the rear susp. should be in the lower hole; is there anything else I should be changing at the same time?
