Trask Billet Aluminum Swingarm Kit - 25+ Softail Gen 2

A more planted Softail starts at the rear of the chassis. The Trask Gen 2 Billet Aluminum Swingarm reduces weight and increases rigidity, improving stability through corners, at speed and under hard acceleration.

Designed specifically for 2025 and newer Harley-Davidson Softail models, the Gen 2 swingarm is precision-machined from solid T6061 billet aluminum. Pocketed joints remove unnecessary material while the bolt-together construction eliminates welded connections and simplifies installation.
