Trask Performance is an industry leader in high-performance Harley-Davidson aftermarket parts — known for their turbo kits, stainless steel exhaust systems, and precision CNC-machined billet components. Every Trask part is dyno-developed and made in the USA.
Founded in Phoenix, Arizona, Trask Performance built their reputation around forced induction — and their Tornado Turbo kits remain the gold standard for Harley-Davidson turbo systems. Designed for Big Twin engines, Trask turbo kits deliver dramatic horsepower gains with the reliability and fitment quality that serious builders demand. Pair one with a Trask Assault Charge high-flow air cleaner to maximize airflow and get every pound of torque your engine can produce.
Trask's lineup of stainless steel 2-into-1 exhaust systems is purpose-built for Harley-Davidson Touring and Softail models. The Assault, Nasty Bastard, Big Sexy, BMF, and Up Yours series are all built from seamless steel pipe, dyno tested, and available in stainless, chrome, black, and polished finishes. Whether you're building a bagger or a custom Softail, Trask exhausts deliver an aggressive sound and real performance gains right out of the box.
Beyond the power upgrades, Trask's CNC-machined billet aluminum parts bring the same precision to every corner of your build. Shop cam covers, derby covers, power plate clutch upgrades, titanium axle kits, billet swingarms, frame tail sections, and vented transmission covers — all engineered for direct bolt-on fitment across Harley-Davidson Touring, Softail, Dyna, and Sportster platforms from the late 1990s through current model year.
