Shearer Fabrications HiRam Sheetmetal Lid

Our new Sheetmetal Lid for HiRam/LoRam Flanged manifolds. These are constructed entirely in house from USA processed aluminum.

Our 105mm opening, 3d contoured, throttle body flange has both Ford and LS bolt patterns to accommodate almost any throttle body out there.
