Mustang axle reservoir "KR" style, complete with fittings, Fragola blue anodized plug, hose and hose clamps. Great addition for road racers. These axle reservoirs are designed to keep the expanding rear axle fluid off the track - as the axle oil heats and expands, the fluid moves upward into the reservoir and drains back as fluid cools. Fits 2005-current mustangs, gt, shelby, V6 etc NOTE : WILL NOT FIT 2013-14 GT500 WITH TRACK PAC (Diff oil cooler)
