Springfield KingPin Boat Seat Pedestals: Standard vs Threaded
KingPin boat-seat posts do not all lock into the same deck base. Springfield manufactures standard-pin and threaded KingPin configurations, as well as fixed, manual-adjusting and Power-Rise pedestal assemblies. Check the original base style, installed seat height and seat-mount components before selecting a replacement.
Standard and threaded KingPin are different connections
The standard-pin 1612401-A and 1612402-A Power-Rise pedestals require the matching standard KingPin base. The 1630411-A, 1630423-A, 1630801-A and 1632013-A parts use a threaded KingPin connection. An identical height range does not make the bases interchangeable.
Check the seat position and manufacturer classification: These KingPin products are identified with ABYC H-31 B fishing-seat ratings. Do not assume they are appropriate for every helm or underway seating position. Confirm the boat's seating requirements, base fasteners and deck support.

KingPin pedestal questions
Do 1612402-A and 1632013-A use the same base?
No. Both offer a 22½–29½-inch height range, but 1612402-A is the standard KingPin design and 1632013-A uses a threaded KingPin base.
Are 1630411-A and 1630423-A adjustable?
No. They are fixed threaded posts measuring 11 and 15 inches, respectively, and do not include seat mounts.
How does 1630801-A adjust?
Its threaded KingPin post adjusts manually from 22 to 31 inches in one-inch steps and uses a Posi-Lock lever to hold the selected height.
Can I fit KingPin parts to a Springfield Mainstay or Taper-Lock base?
Do not assume so. These are separate base connection families. Use the original system's exact manufacturer part numbers and approved combination.
Are all of these for use at the helm?
No universal helm suitability is established. Follow the seat's ABYC designation and vessel-specific mounting requirements for its intended position.
