These compression type couplings consist of bonded rubber joints pressed into the sockets of metal hubs. These dynafocal engine suspensions provide proper flexible support to isolate engine vibrations and reduce noise transmission to airframe structure in all aircraft applications. Careful design assures maximum strength to hold the engine under ultimate load and emergency conditions. Suspensions also distribute loads in most desirable patterns, control engine motions, accommodate thermal expansion and manufacturers’ tolerances.

Raised the nose of my O-540 6MM due to the old worn mounts. Expensive but hopefully they last awhile

Q: What is the shelf life of these Lord engine mounts counting from cure date?

Per the supplier: shelf life on the Lord engine mounts is 20 years.

Q: Does these Lord mounts come in kits? How many comes in each kit?

No, these are priced and sold individually. There will be 2 pieces in the box as a sandwich kit, but if you required 4 for your engine, you would need to order quantity 4.

Q: Is there a way to reference the bolts that would go with these Lord mounts?

Engine mount bolts are not always the same length for every aircraft application. The size is in an aircraft parts manual, or the mechanic will need to take measurements on the aircraft to determine the correct bolts.

Q: Do these Lord mounts come with installation instructions such as orientation and torque setting? I have read that these have to be positioned correctly or can be installed upside down?

They do not. That info should be in your aircraft maintenance manual.
