The 300EX and the 250X’s from the 1990’s use the same Widening and Lowering Kit.
The kit uses all of the same components as the widening kit, except the shock widening components are not included. By widening the mounts for the a-arms, but keeping the upper shock mounts in the stock location, the suspension “squats” and lowers the front of the ATV by about 3 1/2 inches.
Stock brake lines should be long enough to install either the +4.5” or the +6.0″ kit if you disconnect the intermediate brake line support on the a-arms to provide more slack in the lines.
Diamond J Customs does sell brake lines if you would prefer to use extended-length stainless steel braided brake lines with your widening kit.
