This cutting-edge turbocharger system is designed to give your Softail serious bite, making it a true force to be reckoned with on the open road.

The Perfect Upgrade for Softail Owners

The Assault Turbo Kit was initially crafted exclusively for Assault Charge custom bikes, but now you can bring the same incredible performance to your Softail. Engineered for Harley Davidson enthusiasts, this kit delivers a thrilling boost in both horsepower and torque, giving you the power you need to take your riding experience to the next level.

The kit features a bold, aggressive design, including a sawed-off exhaust with sleek heat shields, ensuring your Softail looks as fierce as it performs. Whether you're accelerating off the line or enjoying the unique roar of a Harley Big-Twinturbocharged engine, the Assault Turbo Kit amplifies your ride in a way that nothing else can.

Key Features of the Assault Turbo Kit

  • Garrett Turbocharger for maximum airflow and power
  • Plenum Assembly with integrated BOV & 2 Bar Map Sensor for improved tuning
  • Stainless Steel Header Pipe and Heat Shields for durability and heat management
  • Heavy Duty Clutch Spring for smoother power delivery
  • Boost Gauge & Mount to monitor turbo performance
  • High Flow Injectors and NGK Spark Plugs for enhanced fuel delivery
  • Turbo Cam Cover and Tail Pipe designed specifically for your turbo setup

With all of these components included, the Assault Turbo Kit is the most comprehensive performance upgrade for your Harley Davidson Softail. It’s engineered to make sure you get the most out of your bike, whether you’re racing down the highway or taking on winding roads.

Choosing the Right Turbo Kit for Your Harley Davidson Softail

Before purchasing the Assault Turbo Kit, it's important to select the correct version for your bike's specifications. Here's what you need to know:

Step 1: Choose Your Softail's Year Range

To ensure you get the right parts for your bike, start by selecting the year range your Harley Davidson Softail falls into. This step guarantees compatibility and optimal performance.

Step 2: Select Stage 1 or Stage 2 Kit

  • Stage 1 Kit – Ideal for bikes with stock displacements from 88" to 117". We recommend using the Stage 1 kit for Harley Davidson Softail models that fit within this range. It provides excellent performance but is not suited for larger displacement motors.

  • Stage 2 Kit – Designed for larger displacement engines (120" and above). This kit can also be used for smaller displacements (like the 114" engine) if you plan to upgrade the motor to a larger size in the future, such as a 128" motor. Stage 2 kits provide more aggressive power output and are perfect for riders seeking maximum performance.

What's Included in the Assault Turbo Kit

Every Trask Turbo Kit includes the following high-quality components:

  • Garrett Turbo Charger
  • Plenum Assembly with integrated BOV & 2 Bar Map Sensor
  • Stainless Steel Header Pipe and Heat Shields
  • Turbo Cam Cover
  • Boost Gauge & Mount
  • Heavy Duty Clutch Spring
  • High Flow Injectors
  • NGK Spark Plugs
  • Complete Hardware Kit and Gaskets

Please note that the kit does not include a Thundermax ECU. However, Trask Performance will provide a base map for your newly purchased kit, even if you already have a Thundermax installed.

Important Compatibility Notes

Before purchasing, be sure to check the following:

  • Non-removable lower fairings on liquid-cooled models may not be compatible with the Trask Turbo Kit.
  • Engine guards may not be compatible with the kit, depending on the design of your Softail.

Legal Notice

Trask Turbo Kits are not legal for sale or use on any pollution-controlled motor vehicles in the United States. Please check your local laws and regulations before installing the kit on your Harley Davidson Softail.
