Springfield Trac-Lock III Boat Seat Slide, 2-3/8in Non-Locking Swivel

The Springfield Trac-Lock III slide is the piece that turns a bare 2-3/8 inch pedestal post into a real, adjustable helm seat. It drops between your post and your seat, and it does two jobs at once. It slides the seat fore and aft so you can dial in the right distance to the wheel or the tiller, and it swivels a full 360 degrees so you can spin around to work a rod, talk to the crew, or step off cleanly at the dock.

This is the non-locking version. The swivel turns freely through the whole circle, which most anglers actually prefer at anchor or drifting. Stand up, turn, sit back down, no lever to fuss with. It's the without-handle model, so there's no side lever hanging off the slide either. Fewer parts to snag a line on, and a cleaner look under the seat.

Construction is powder-coated aluminum, so it carries a seat and a full-grown adult without flexing, and it won't rust the way a steel slide will. Springfield builds these to meet ABYC Class H-31 AP, the recreational-boat seating standard, so you're not guessing about whether the mount is rated for the job. It fits any 2-3/8 inch diameter post, the most common pedestal size on center consoles, bay boats, and aluminum fishing rigs. If you're already running a 2-3/8 inch Springfield or Taper-Lock style base, this slide sits right on top.

The slide track itself is what Springfield calls Trac-Lock III, their third-generation seat slide. The seat bolts to the top plate using a standard boat-seat bolt pattern, so most aftermarket helm seats, folding seats, and cushioned buckets drop right on. The whole assembly stays low-profile, so you're not jacking your seating height up several inches and throwing off your sightlines over the console.

Where does it shine? Boats in the 17 to 23 foot range where the helm seat does double duty. You run to the spot facing forward, then swivel around and fish the same seat. It works just as well on a jon boat or a tinny where a swivel seat beats a fixed bench, and on pontoons where folks like to turn and face the group. The fore-aft travel matters more than people expect. A few inches of adjustment is the difference between reaching the wheel comfortably and perching on the edge of the cushion all day.

A few honest notes, because we'd rather you rig it right the first time. Because the swivel is non-locking, it'll rotate on its own in a real chop or a following sea. That's fine at rest, but if you want the seat to hold a heading while you're underway, this isn't the locking model. Measure your post before you order, too. 2-3/8 inch needs to be the actual outside diameter, not close to it. An undersized post lets the slide wobble, and a little play now turns into a rattle later.

If you run in salt, treat the aluminum like you would any other underseat hardware. A little dielectric grease at the post joint keeps the dissimilar metals from chewing on each other, and a freshwater rinse at the end of the day goes a long way. Mounting to thin fiberglass or a flat deck? Back it with a proper plate underneath so the load spreads out instead of working the gelcoat. On a solid leaning post or a factory console pad, you can bolt straight through.

Installation is straightforward for anyone comfortable with a socket set. The slide clamps down over the 2-3/8 inch post, the seat bolts to the top, and a bushing at the post connection takes up tolerance and keeps the swivel turning smooth. Budget about twenty minutes if the post is already in place. And remember the post and base are sold separately. This slide is the top piece of that stack, not the whole pedestal.

What it isn't: it's not the locking-swivel version, and without the handle you're repositioning by hand rather than with a lever, which takes a second to get used to on a moving boat. But for a knockaround fishing seat that spins free and adjusts fast, this one's tough to beat. It's a no-nonsense upgrade for anyone tired of a seat that only faces one way.
