Spark ARC ST PRO

The Spark ARC ST PRO is a lightweight splitboard binding built around Spark’s Tesla T1 base, with a carbon-reinforced highback, dedicated straps and drilled pins that reduce weight while preserving dependable performance. Its responsive construction and custom 7075-T6 aluminum hardware make it especially well suited to demanding backcountry missions.

On the ascent, the Whammy Bar provides straightforward angle adjustment, while the puck-based system enables quick transitions between climbing and riding modes. The ARC’s more forgiving spoiler and strap design suit splitboarders who value efficient touring, low weight and comfortable, responsive handling on the descent.
