NT3030ELS-KIT
Spring Brake Piggyback Kit
Bendix

Spring brake piggyback kit assembled for the 3030 chamber family, this kit provides a compact, integrated solution for combining service and parking functions within a single housing. VMRS code 013-004-027 places it within a subset of spring brake components that address chamber capacity, actuation speed, and reliability. The dimensional data includes a length of 11.97 inches, a port angle of 0 degrees, a stroke length of 3 inches, and thread sizes of 3/8-18 NPT for both parking and service ports, which informs compatibility with common air plumbing configurations and mounting footprints. Temperature operating range from -40 to +175 DegF supports operation across extreme climates, while construction notes indicate a 3030 chamber type for robust sealing and predictable performance. Cross references ABP N42A 30PBK3D and SLV 3030PBKLS indicate alternative supplier or catalog designations that fleets may encounter in parts catalogs. Category 41368 reflects its specialized role in spring brake systems, offering efficient service replacement and streamlined maintenance planning for heavy haul and vocational fleets. In practical terms, the piggyback arrangement reduces installation complexity, improves serviceability during brake chamber maintenance, and can contribute to faster repair times in remote maintenance environments.
