This 5-pack of parking brake knobs is built for use with air valve controls on Mack and Navistar trucks. Each set includes a spiral pin along with the parking brake knob needed for installation, and all five knobs in the pack are identical. It is intended as a complete replacement set rather than a single unit, giving the shop enough knobs on hand for multiple installations.Interchanges:25160623745-101471745-248502Mack 25MY32P19Navistar 451650C1This unit is sold in packs of 5.FeaturesPack of 5 parking brake control knobsIncludes spiral pin (LPN-5119) and parking brake knob (LVK-3603-001)Universal use applicationTech SpecsKit contents: 1x Spiral Pin (LPN-5119), 1x Parking Brake Knob (LVK-3603-001)Sell pack: 5 pieces
