TRASK Assassin Turbo Kit for Harley Davidson Baggers: Unmatched Performance & Style

If you're seeking the ultimate in performance and style for your Harley Davidson Bagger, look no further than the TRASK Assassin Turbo Kit. Designed to enhance both the power and aesthetics of your ride, this turbo kit is a game-changer for those who demand the best from their M8 motor builds. Whether you're upgrading a stock bike or building a high-performance bagger, the TRASK Assassin Turbo Kit delivers unbeatable performance and a custom look that will set your bike apart.

Key Features of the TRASK Assassin Turbo Kit

The Assassin Turbo Kit features a V-Band exhaust housing with a 3” discharge pipe made from pie-cut stainless steel. This design provides a unique, custom look while ensuring superior performance for even the largest displacement M8 engine builds. Originally introduced as part of the Assault Glide performance bagger builds, it has since become the best-selling Stage 2 kit, found on some of the most powerful M8 street bikes on the road.

TRASK Turbo Kit Components Include:

  • Garrett Turbocharger for optimal power delivery
  • Plenum Assembly with integrated BOV (Blow-Off Valve) and 2 Bar Map Sensor
  • Stainless Steel Header Pipe with heat shields for durability and style
  • Tail Pipe tailored for your chosen turbo kit style
  • Turbo Cam Cover for enhanced performance
  • Boost Gauge & Mount for precise monitoring
  • Heavy Duty Clutch Spring for smooth operation
  • High Flow Injectors to fuel your power upgrades
  • NGK Spark Plugs for reliable ignition
  • Hardware Kit and Gaskets for easy installation

Note: The kit does not include a Thundermax ECU, but Trask Performance will supply a base map for all newly purchased kits, even if your bike already has a Thundermax installed.

Choosing the Right Turbo Kit for Your Harley Davidson Bagger

When selecting the Assassin Turbo Kit for your bike, it's essential to choose the correct configuration to match your bike's displacement and build goals. Here’s what you need to know:

Stage 1 Turbo Kit vs. Stage 2 Turbo Kit

  • Stage 1 Kit: Designed for bikes with stock displacements between 88”-117”. We recommend against using this on larger displacement motors. If you plan on building your motor to a larger size later, opt for the Stage 2 Kit.

  • Stage 2 Kit: Ideal for larger displacement engines (120” and above), but can also be installed on smaller motors (e.g., a 114” motor) if you plan to build it to a larger displacement in the future, such as a 128”.

Why Choose the TRASK Assassin Turbo Kit?

The TRASK Assassin Turbo Kit is the ultimate performance upgrade for Harley Davidson baggers, delivering both style and power. Whether you’re cruising the streets or hitting the open road, this kit offers unmatched performance that will transform your ride. Don't settle for less—upgrade your Harley with the Assassin Turbo Kit and experience the thrill of superior power and style.

Note on Legal Compliance

This kit is not legal for sale or use in the United States on pollution-controlled motor vehicles.

Important Considerations Before Purchasing

  • Year Range Compatibility: Be sure to select the correct year range for your Harley Davidson Bagger to ensure compatibility with your bike’s parts.
  • Engine Guard & Fairing Compatibility: Trask Turbo Kits are not compatible with non-removable lower fairings, such as those on liquid-cooled models, and may not work with all engine guards.
  • Lead Time: Due to demand, lead time for the kit is typically 4-5 weeks, though this may vary seasonally.
