Inverted Bushings Extra Hard 99A
Tight Control for Your Ace AF1 Inverted Trucks
Do your trucks feel too wobbly when you’re skating faster or landing harder? Then the Extra Hard Bushings (99A) will significantly stiffen your steering response. Your board will react more directly and be much harder to push sideways. They’re designed as replacements for the Ace AF1 Inverted Trucks—they’re not meant for use on other trucks. If you’re heavier or ride aggressively, this will give you a stiff setup. If you prefer a looser feel, go for a softer hardness. The set is available in white.
Features:
- 99A hardness (Extra Hard): tight, precise steering instead of a spongy feel
- For top and bottom: Top and bottom bushings have the same hardness, keeping your setup consistent
- Specially designed for AF1 Inverted: compatible with Ace’s Inverted Trucks
- Barrel and cone shapes: you can swap out both sides of the truck at once
Package contents:
- 2 barrel bushings, 2 cone bushings, and 4 cup washers

Riser Pads
Riser pads are used to increase the distance between the wheels and the deck in order to prevent undesirable contact between the wheels and the deck (wheel bites) when turning.
No riser pads = 7/8" to 1" screw length
1/8" riser pads = 1" to 1 1/8" screw length
1/4" riser pads = 1 1/4" screw length

1/2" riser pads = 1 1/2" screw length

Trucks
Information about the correct skateboard truck width:
All truck manufacturers provide their trucks in different size charts. For an 8" deck, you can use an Independent 139", a Thunder 147", or a Titus 5.3" truck. To determine which truck fits perfectly under your deck, consult the size chart. The length of the truck axle should ideally match the width of the deck. Trucks should not be wider than the deck itself whenever possible. When in doubt, you can simply follow our recommendations for the appropriate deck width when choosing your trucks.
Truck Height:
Truck height is measured from the baseplate to the center of the axle. There are three different types of truck constructions that primarily differ in their height:
Low trucks provide a more direct board feel due to their lower center of gravity but should only be used with wheels up to 53mm to avoid wheel bite.
Mid trucks are the standard when it comes to truck height.
High trucks offer a wider turning angle due to their additional height.
For more detailed information on skateboard trucks, you can refer to the Titus Skateboard Guide.
