    UMI Performance's frame C-notch kit provides rear axle clearance for a lowered 1973 through 1987 GM C10 and C15 fullsize truck or Suburban. The 3/16 inch steel plates bolt on to notch the rear frame rails so the axle can travel higher without contacting the frame, which is essential when running a lowered rear ride height. A black powder coat finish protects the steel from corrosion. UMI Performance manufactures this kit in the USA.
