Sized to fit properly in conventional "Indy-style" trucks.
Custom APS Urethane Formula for ultra-performance and sweet rebound.
Hard durometer bushings (97.5a) for heavier weight riders & are designed for those looking for a very stable setup in the Board Side position.
Medium durometers (95a) are designed for those looking for a stable setup in the Board Side position.
Soft durometers (90a) are designed for those looking for a slightly less stable setup in the Board Side position
Super soft durometers (85a) are for lightweight, or young riders.
Stiffer bushings will result in a more resistant board, which can be an advantage when performing tricks - lightweight riders may benefit from mixing duro's roadside & board side.
