Ace Theories Hollow Trucks

The hollow kingpin and axle significantly reduce the overall weight of the trucks without compromising structural integrity. This makes flip tricks feel lighter and less fatiguing during longer skate sessions.

While the hollow components reduce weight, they are engineered to maintain the same strength-to-weight ratio as solid trucks. You get the benefit of a lighter setup without sacrificing the durability needed for street or park skating.

Ace sizing corresponds to deck width: size 33 is typically best for 7.75" to 8.125" decks, size 44 for 8.125" to 8.375" decks, and size 55 for 8.375" to 8.75" decks. Always match your truck width as closely as possible to your deck width for optimal stability.
