Ace Trucks are one of the most popular trucks in skateboarding, but their numbered sizing (22, 33, 44, 55, 66) confuses a lot of people. This guide covers which size fits your deck and the difference between the AF1, AF1 Hollow, AF1 Low, Inverted and Classic, so you can pick the right set first time.
Ace Trucks size chart
Ace names its trucks by number instead of axle width. Find your deck width in the right-hand column:
| Ace size | Axle width | Fits decks |
|---|---|---|
| 22 | 7.75" | 7.25" – 8.0" |
| 33 | 8.0" | 8.0" – 8.25" |
| 44 | 8.25" | 8.25" – 8.5" |
| 55 | 8.5" | 8.5" – 8.75" |
| 60 | 8.75" | 8.75" – 9.0" |
| 66 | 9.0" | 9.0" – 9.25" |
Quick rule: your truck's axle should sit roughly in line with the edge of your deck. If your deck is between two sizes, most skaters go with the smaller truck for street and the bigger one for transition.
Most popular sizes: 44 (8.25") and 55 (8.5"), since they match the most common deck widths.
Which Ace truck should you get?
Ace AF1: the all-rounder. Ace's flagship truck, and the one most people should start with. It's cast from high-grade AA 356.2 aluminium, heat-treated for strength, and has oversized steel axles to stop bearing wobble. The axle nuts re-thread the axle as you tighten them, so damaged axle ends are less of a problem.
Ace AF1 Hollow: lighter. The same AF1, but with a hollow axle and kingpin, which makes it 8.6% lighter than the standard AF1. Good if you want a lighter setup for flip tricks without losing strength.
Ace AF1 Low: lower to the ground. A lower-profile AF1 for skaters who run smaller wheels and want a lower, snappier feel for technical street skating.
Ace AF1 Inverted: best for grinds. Ace's most technical truck. The kingpin is flipped upside down, so nothing sticks out to catch on grinds, giving the lowest grind clearance of any kingpin. It also has a hollow axle, and each truck comes with a magnetic adaptor that turns any skate tool into an inverted-kingpin tool.
Ace Classic: the original. Ace's classic design, machine polished, for skaters who like the original Ace feel.
Not sure? Go AF1. It suits street, park and bowl, and it's the one we recommend most.
Bushings and pivot cups
Bushings control how your truck turns. Stock AF1 bushings are 91a on top and 86a underneath. If your trucks feel too loose or too stiff after tightening or loosening the kingpin nut, swap the bushings:
- Ace Bushings Standard: for a regular, responsive turn.
- Ace Bushings Hard: for heavier skaters or anyone who wants a stiffer, more stable truck.
Pivot cups wear out over time and cause a clunky feel. Ace makes separate pivot cups for the AF1 and the Classic, so make sure you get the one that matches your trucks.
Keep your Ace trucks running
- Ace Re-Threader Dies: drop into any skate tool to fix damaged axle and kingpin threads. A set comes with every AF1, and you can buy spares.
- Ace AF1 Skate Tool: a compact folding tool with re-threaders built in.
- Ace Classic Skate Tool: a T-shaped tool that folds down small.
