Features

Axle/Kingpin Style

Hollow Axle - Hollow axle trucks cut down on the materials used in the axle, so your trucks feel lighter, because they are lighter.

Inverted Kingpin - An inverted kingpin means the threads are in the trucks, meaning that even after prolonged grinding, you will always be able to tighten or loosen your trucks.

Non-Compatible Risers

Risers from the following brands are not compatible with the baseplates of these trucks.

Diamond, Girl, Independent, Loaded, Paris

Ace AF-1 Inverted Hollow Skateboard Trucks - polished silver 44

Youre going to love how these turn and the difference you feel with the grind clearance. Smiths and Feebles are especially interesting on rails. You can get a lot of dip.

Im used to Indy forged Hollow lows, so these Aces sit a bit higher and feel heavier, which matters to me personally. Ive set up two boards and have been alternating between the two for different application.
