The Springfield 2-3/8-Inch Mainstay with Locking Swivel is an adjustable pedestal package that raises the seat from 14-1/2 to 20-1/2 inches using a 500-newton air cylinder. It comes with a locking Trac-Lock swivel and slide, so you can turn the seat and move it fore and aft, then lock it in place. The 2-3/8-inch pedestal and 9-inch round base are high-strength anodized aluminum.
Six inches of travel is a wide range for a 2-3/8-inch pedestal, so one setup can work for drivers of very different heights. This package suits mid-size runabouts, bay boats, and bowriders that do not need the heavier 2-7/8-inch Mainstay. It ships as a complete package, so there is no need to source the swivel, slide, and base separately or worry about matching parts.
Confirm that your seat’s bolt pattern matches the Trac-Lock mount, and that the base sits over solid deck structure or a backing plate. Test the air lift with someone seated, and check all locks before getting underway. Compare both post sizes in our seats, pedestals & slides. Rinse the cylinder shaft and slide tracks with fresh water after saltwater trips so the locks keep engaging cleanly.
