Trask Assault Breather Kit For Harley Twin Cam 1999-2017
Trask Assault Breathers: Mastering the Twin Cam Engine Standard
The Trask Assault Breather Kit for Harley-Davidson Twin Cam (1999-2017) represents the pinnacle of streamlined engine architecture for the serious performance enthusiast. For the rider of a Road Glide, Street Bob, or a custom Twin Cam Softail who values the precision of a competition-grade “Assault” signature as much as long-term structural durability, the challenge has always been finding a ventilation system that bridges the gap between raw, performance-oriented oil control and elite factory-integrated reliability. The Trask system addresses these concerns by providing a rigid, precision-engineered foundation, designed to maximize air-to-oil separation and cylinder head efficiency. This design provides secure, mechanical utility by utilizing a refined, billet aluminum geometry, effectively providing a high-output structural delivery that prevents internal pressure buildup and optimizes balance during high-velocity urban runs and aggressive highway sprints. This provides the mechanical synchronization of engine pressure management and elite motorcycle management needed to keep the rider confident, maximizing the efficiency of your performance run.
Material Innovation and Industrial Precision
What sets the Trask Assault Breather Kit apart in the marketplace is the uncompromising focus on structural stability and metallurgical durability. In the high-performance Twin Cam scene, engine integrity is paramount; however, this system features a robust, precision-machined assembly that ensures the breather ports remain synchronized perfectly without compromising the integrity of the critical intake tract over years of heavy-duty use. The high-quality billet finish is engineered for secure, long-lasting aesthetic appeal, providing a high-output, uniform luster that resists oxidation and harsh environment wear. Every unit is manufactured to exacting tolerances, featuring high-temperature seals for secure, vibration-free installation on all Twin Cam models from 1999 through 2017. Whether you are navigating technical city streets or cruising through mountain passes, Trask ensures your engine remains synchronized by professional-grade engineering integrity.
