because when you go wider you have a wider turning radius
i see what you mean though whne you push out the wheels with washers it is effectively doing the same thing. you also have less meat on the trucks though so grinds would feel a little more tight . and thunders scale the height as well with the width as you know
I think the major difference is the pivot nub thing is longer on >=148 trucks. The bigger trucks also seem to have a bit more meat on the "wings" which makes sens i guess.
Bushings, kingpin and baseplate seem to be the same. Could this lead to a different angle of the trucks with the same bushing height but a short pivot nub?
Intuitively I feel like it could extend the wheelbase marginally, since the 147 should be "tilted" a bit towards the nose and tail? This is purely speculative but I guess this is what this place is meant for^^
Here are some comparison photos of 149 and 147 hangers.
Disclaimer:
These are both used trucks but I guess one does still get the general idea and they are ground kinda equally. The 147 is from 2015 (they still had the yellow bushings). The 149 are from around ~2019 i would guess (blue bushings). Were there any changes in the thunder geometry in the last 10-15 years except for the kingpins when they had supply chain issues because of covid? The baseplate got the hexnut recess but otherwise stayed the same?
Good pics!
I recall someone talking about the way the trucks go up in height, saying that as you said, the baseplate, bushings and everything else besides the hanger are still the same for all, then just the height of the hanger in the upper part of the wider trucks from 148+ being taller than 147s.
This allows the same geometry with the same bushings and everything else, just a bit more kingpin clearance and a bit more overall height. The wheelbase is more or less the same, although as you said it could be pointed out that the angle is not vertical but if you check, I think it is where the axle is positioned in the taller versions which keeps it the same.
Apart from that, as others said the wider you go the more the turn will change, but as to wheelbite, the wider board will usually have more concave up into the edges which will offset that to some degree.
I was messing around with 149, 151 and 161s the other day on the same board, which was almost too tippy on the 149s, then pretty good on the 151s and a little too wide spread on the 161s for the size that it was - 8.75 DLX standard shape - but I could see how all three versions would work for different people.
Yet to see the really wide 181 trucks that came out to go with the Zip Zoggers 10" decks, but I don't think I am missing out at all there.
On some of the smaller boards I have set up for kids or others to use, the 147s feel quite low and small by comparison, as I am way more used to taller wider trucks on most setups nowdays, but they still worked fine on the 8 to 8.25 boards with various wheels, usually with risers and looser trucks to help the light weight bodies turn more easily as well.
