Springfield Trac-Lock Locking Swivel | 3100031-L1
Springfield Trac-Lock Locking Swivel | 3100031-L1 — Product description
The Springfield Trac-Lock locking swivel drops onto a 2-3/8 inch post and gives your boat seat a full 360-degree turn, with a handle that locks it right where you want it. Powder-coated aluminum, built to ABYC H-31 seating standards. If you're running a Trac-Lock pedestal, this is the swivel that goes on top.
If you've got a Springfield Trac-Lock pedestal on your boat, this is the locking swivel that mounts on top of the 2-3/8 inch post. It's the piece that lets your seat spin a full 360 degrees, so you can turn to work a rod, face the helm, or swing around to talk to the crew without climbing out of the chair.
What sets a locking swivel apart from a plain one is the handle. Reach down, pull it, and the seat turns free. Let go, and it locks back into position. That matters when you're running in chop. A free-spinning seat fights you every time the bow drops, and it wears on you over a long day. This one stays put until you decide to move it.
The body is powder-coated aluminum, so it shrugs off salt spray and won't rust out the way plain steel does after a couple of seasons. It carries an ABYC Class H-31 AD rating, the standard that covers boat seats and how they're mounted. In plain terms, it's built to hold up under real loads out on the water, not just look good at the dealer. A bushing is included too, which keeps the swivel action smooth and takes up any play between the swivel and the post.
This swivel is made for the Trac-Lock 2-3/8 inch post specifically, so check your post size before you order. If you're not sure what's under your seat, measure the diameter or send us a photo and we'll sort it out with you. The install is straightforward. Your seat bolts to the top of the swivel, the swivel drops onto the post, and you're back in business. No special tools, no drama.
It's a common wear-and-upgrade part. Maybe your old swivel seized up, maybe you're adding a locking seat to a fishing setup where you want to stay pointed at the water. Either way, this is the direct Springfield replacement for the Trac-Lock system.

Frequently asked questions
What post size does this swivel fit?
It's made for the Springfield Trac-Lock 2-3/8 inch post. Measure your post diameter before ordering, and if you're not sure, send us a photo and we'll confirm the fit.
How does the locking feature work?
There's a handle on the swivel. Pull it and the seat turns free through a full 360 degrees. Release it and the swivel locks back into position, so the seat stays put while you're underway.
Is it really 360 degrees of rotation?
Yes. The seat can turn a complete circle on the post, which is handy for fishing, running the helm, or turning to face the crew.
What's it made of?
Powder-coated aluminum. That combination holds up to salt spray and won't rust out the way plain steel does after a few seasons on the water.
What does the ABYC Class H-31 rating mean?
ABYC H-31 is the marine industry standard covering boat seats and their mounting hardware. This swivel is built to meet those strength requirements for seat attachment.
Is a bushing included?
Yes, a bushing ships with the swivel. It keeps the rotation smooth and takes up any slack between the swivel and the post.
Will my seat bolt right to it?
The seat mounts to the top of the swivel, then the swivel drops onto the Trac-Lock post. It's a straightforward swap with basic hand tools.
