General Description N/A These mounts are designed to support engines, cabs and accessory units, accommodate frame racking and twisting while isolating vibration and absorbing shock.
Typical applications for Two-Piece Mounts include on-highway, off-highway vehicles, construction and industrial machines.
Note N/A All parts made of low carbon steel.
For applications in severe oil environments, contact Lord Corporation. Based on extensive experience, Two-Piece Mounts have been designed to operate in normal fluid, temperature and other environmental conditions such as found in the engine compartment of on- and off-highway applications.
  • 1 These loads are for on-highway and general industrial use. For off-highway, use 80% of the load shown.
