Dependable & Predictable.
Built for steep drops, hard banking turns, and zero surprises on critical wave faces. While skatey twin-plus setups are made to slide and release, the 4Runner is engineered for surfers who need absolute grip and stability when pushing hard through a turn.
By pairing full-sized drive fronts with substantial, raked quad trailers, this set keeps the tail firmly planted in the water column. When you bottom turn off a steep section or bank hard into the pocket, it tracks cleanly with dependable, predictable bite instead of washing out or skating free. Laid up in solid fiberglass with custom resin tints, it eliminates high-speed chatter, cuts through surface chop, and converts pure rail pressure into controlled forward momentum.
