These are tie bars used when linking dual and triple engines in hydraulic steering systems with pivot mount outboard hydraulic cylinders.
For triple engine applications, add a second tie bar kit of the type you would use for a dual engine set-up. This will be determined by the number of cylinders used, and the engine type.
Kits include the adapter plates, tie bar, and hardware required to connect twin engines utilizing single or twin front mount outboard cylinder(s).
