www.holzracingproducts.com for the holz skid. Them other skid is actually called K-mod, bullydog is a dealer fot it. You can get hold of Kevin at 1-208-681-0348. The RX1 skid is 1050 usd. You will reuse your front shock and lower bracket. The holz comes with a different center shock, maybe that why its a little more. Both skids are pretty much the same thing. Not sure if the Holz really drops 34lbs, since 8lbs is in getting rid of the stock yami brackets, which would put it about 24lbs, same as K-mod claims, Tundra said his down 21.5lbs, so pretty close to advertised.
