Product Description


Dynojet Thunderslide Carburetor Jet Kit

Every Dynojet Thunderslide jet kit is designed specifically for your Harley Davidson to increase engine power, smoothness and throttle response. Each kit provides optimum performance throughout the rev range for maximum power and optimum fuel economy.

  • Thunderslide Jet Kits include a composite slide to replace the old aluminum slide. This gives you better throttle response and higher fuel economy

These kits are available in two types to suit your riding needs:

Choose the correct kit for your needs:

Stage 1 jet kits

Ideal for bikes with a stock engine using the stock airbox, air filter and stock pipe. Stage 1 kits are fully adjustable to work with well-designed aftermarket pipes as well as stock replacement air filters.

Stage 1 kits improve throttle response and driveability. In most cases, power increases of approximately 5% throughout the entire power range can be achieved with correct tuning.

Stage 7 jet kits

For race only use or for special applications with a complete induction kit. Stage 7 kits are designed to optimize jetting for a given tuning specification or racing conditions.

    Yes, you'll find that, not only will it make fuel delivery ideal for your bike's configuration, but also - throttle response will be better than stock.
