Supercross Pro and Pro LT forks have proven themselves for decades as the standard which all others are judged. For 2010 the new SLT's have surpassed anything that anyone could of dreamed of. The SLT's feature a new larger Butted and Tapered Leg, a Forged Cro-mo Internal Spiral Fluted Steertube with welded in star nut, new smaller micro 1/4" thick cro-mo dropouts. full black oxide rust proofing inside and out, full post weld heat treatment, all of this with NO WEIGHT limit and weigh in at a scant 27 ounces ( 20" Fork ). Truly a Super Fork! Hence the SLT name. These forks will put up with the punishment of the skate park, the trails and are still light enough to go race in the AA Pro class.
