Hollow Kingpin - Lightening the load, hollow kingpins reduce weight for lighter feeling trucks, while still maintaining strength in this critical area.
Hollow Axle - Hollow axle trucks cut down on the materials used in the axle, so your trucks feel lighter, because they are lighter.
Sizing Reference
Note - Every skate truck brand represents their sizing a little differently, so it's easy to get confused. Take a look at this graphic and then reference the size chart.
Got these to setup a 14" Eggzilla 3 with 55mm 78a OJ Mini Super Juice wheels. Man is that setup fun to ride. I like my trucks loose and turney and went up to 3/4" risers to eliminate wheel bite. And these trucks just want to grind and give very little resistance on the local curb. For fat boards these are ideal imo.
They fit beautifully on my 11Alva Abstrakt deck. The soft bushings and geometry make the truck surprisingly turny for being so wide (make sure to add risers or swap for harder bushings if need be) They grind well on curbs but yes you will need to get used to the size, but you already knew that if youre buying something like this. In summary if you want to pull the trigger on getting a huge deck, these trucks are way fun and will suit your fancy.
