Industry FB's 40 mm Trucks Land at Maple Lab, Built Around a Heavier Alloy

Width drives the rest of the design. Once a hanger stretches to 40 mm, the kingpin and the bushing stack sit further out in the path of whatever edge you are grinding, which is the practical reason a maker drops both and calls it out first. The same goes for the larger bushing seat: a wider hanger puts more leverage through that seat every time the board turns, and a bigger seat is the cheap structural answer.

The heavy alloy is the part worth watching. Weight on a fingerboard truck is not neutral — more mass under the deck changes how the board settles onto coping and how it sits on an edge mid-grind, and it changes the sound. Industry FB is selling feel here rather than a number, and without a published weight there is no way to compare it to a standard aluminum truck on paper.

The convertible baseplate is the detail that will get argued about. The listing calls the design innovative; what it concretely offers is a choice between a traditional kingpin with locknuts and a reverse kingpin configuration on the same baseplate, so turning response can be tuned without buying a second set.

Maple Lab's page is a spec summary, not a full build sheet. It does not state what is in the box beyond the trucks themselves — whether bushings, locknuts, pivot cups and axle nuts all ship together, and whether the reverse kingpin conversion needs parts you supply. Bushing hardness options are not listed either, which matters on a truck this wide if you want it loose.
