• The HI4 is Harleys new go to performance longboard for anything up to a bit over head faces. Its wider all round with more plane shape curve making it incredibly loose and easy to turn. It utilizes the easy continual HIHP rocker with the last 6 inches flipped up so with the wider dimensions its still very at home in the pocket. The even rocker, nose concave and the wider nose combination makes the HI4 the easiest to walk and nose ride of the HI series.

Thunderbolt Technologies:

Thunderbolt Technology utilizes advanced materials and technology to decrease weight while enhancing performance, flex characteristics, board control, and durability.

Mass-produced epoxy boards are corky and stiff. While light and durable, they simply dont ride well. But Thunderbolts hand-built boards take superior epoxy materials to an entirely different level. These boards provide the feel and sensitivity of a good poly board, but deliver performance far beyond traditional epoxy pop-out constructions. Indeed, those who ride these high-tech epoxy boards claim they actually feel better than polyurethane.

Thunderbolt boards are 100% hand layups. They begin with an EPS foam core with multi-component carbon fiber stringer systems that produce engineered flex and twist for a more lively, responsive performance. Proprietary designs employing internal carbon fiber components are then arrayed in the deck and bottom of the deck for precise flex control and strength.

The core shield PVC provides flexible protection to increase strength and durability without compromising the flex and twist characteristics built into the blank. With ample carbon fiber and fiberglass in the deck, bottom, and rails, these boards both outperform and outlast traditional PU boards and other epoxy designs.
