Key Features
- Formula Four Urethane: Specifically developed to provide more speed, a more consistent slide, and unmatched flat-spot resistance.
- Radial Full Shape: A wide, stable riding surface for maximum control, combined with rounded edges for effortless lock-ins on grinds.
- 56mm All-Terrain Size: The perfect "hybrid" size—large enough for transition and bowl skating, but still agile enough for heavy-hitting street sessions.
- 99D Durometer: The industry standard for versatile performance, offering enough "grip" for slick concrete and enough "give" for crusty street spots.
- Custom Swirl Aesthetic: Each wheel features a unique Green and Purple swirl pattern, ensuring no two sets look exactly alike.
Note: Includes one (1) set of four (4) wheels. Bearings are not included. Due to the 56mm size, we recommend using 1/8" riser pads depending on your truck height to avoid wheel bite.
