It keeps the classic Ace geometry and 53mm mid height, with a 12mm 91a top bushing and 14mm 86a bottom bushing for a smooth, controlled turn and a board that feels lighter under your feet.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHollow axle and kingpin:\u003c\/strong\u003e about 8.6% lighter than a standard AF1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e55 size, 8.5\" axle:\u003c\/strong\u003e made for 8.3\"–8.75\" decks\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAF1 casting and T6 heat treatment:\u003c\/strong\u003e AA 356.2 alloy hanger and baseplate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOversized SAE 4140 steel axles:\u003c\/strong\u003e built to cut bearing wobble\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual-hardness bushings:\u003c\/strong\u003e 91a top, 86a bottom for a smooth, controlled turn\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRethreading axle nuts:\u003c\/strong\u003e clean up damaged axle threads as you tighten\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSold as a pair:\u003c\/strong\u003e two trucks, enough for one board\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSpecs\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e Ace AF1 Hollow 55\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAxle width:\u003c\/strong\u003e 8.5\" (215mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHanger width:\u003c\/strong\u003e 5.8\" (149mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight:\u003c\/strong\u003e 2.1\" (53mm), mid\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits boards:\u003c\/strong\u003e 8.3\"–8.75\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e approx. 368g per truck\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKingpin and axle:\u003c\/strong\u003e Hollow\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBushings:\u003c\/strong\u003e 12mm 91a top, 14mm 86a bottom\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePivot cups:\u003c\/strong\u003e Hand-poured 96a urethane\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e AA 356.2 alloy, True T6 heat-treated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Raw polished\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSold as:\u003c\/strong\u003e Pair (2 trucks)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat Size Board Does It Fit?\u003c\/h3\u003e\n\u003cp\u003eMatch the truck's axle width to your deck width, ideally within about 1\/8\" and no more than about 1\/4\" either side, so the wheels sit right under the edge of the board.

Joey Pulsifer joined as a third partner in 2017.\u003c\/p\u003e\n\u003cp\u003eAce is known for its smooth, easy turn and clean, classic looks. In April 2021 it launched the AF1, cast with Ace's own process for a big jump in strength without changing the geometry riders already loved. Ace backs new trucks against manufacturing defects for their usable life to the original owner, which is a big part of why skaters trust them for street, park and bowl.\u003c\/p\u003e\n\n\u003ch3\u003eFAQs\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eWhat size board do the Ace AF1 Hollow 55 trucks fit?\u003c\/strong\u003e\u003cbr\u003e\nThe Ace AF1 Hollow 55 has an 8.5\" axle and fits decks from 8.3\" to 8.75\". Ace sizes its trucks by number, not width, so check the chart above if you're between sizes. The Hollow uses the same sizing as the standard AF1.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eAre hollow trucks as strong as standard trucks?\u003c\/strong\u003e\u003cbr\u003e\nAce says yes. The hollow parts are the axle and kingpin, which saves weight, while the hanger and baseplate use the same AF1 casting and heat treatment. You get a lighter truck with the same geometry and turn.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow tight should I set my Ace AF1 Hollow 55 trucks?\u003c\/strong\u003e\u003cbr\u003e\nStart with the kingpin nut snug, then loosen it a quarter turn at a time until the board turns easily without wobbling at speed. Ace trucks are known for a smooth, easy turn, so many skaters run them a little tighter than other trucks. Always leave at least two threads showing above the nut.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDo I need risers with the Ace AF1 Hollow 55?\u003c\/strong\u003e\u003cbr\u003e\nUsually not. At 53mm tall, they suit most street and park wheels up to about 56mm without risers. If you run bigger or softer wheels, or loose trucks that let the wheels touch the deck in hard turns, add a 1\/8\" riser and use 1\/4\" longer bolts.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDo these come as a pair?\u003c\/strong\u003e\u003cbr\u003e\nYes.
