Quick answer

Pick the FOX GRIP-Street Performance 41mm cartridge if your Harley-Davidson Touring has 41mm forks; choose the 49mm version if it has 49mm forks. The 49mm model also offers an adjustable ride height option that the 41mm does not.

Why fork size matters

Your Harley-Davidson Touring model determines the fork tube diameter — either 41mm or 49mm. The cartridge must match that diameter to install correctly, so measuring or checking your bike's specifications is the first step. Both sizes use the same opposed-piston sealed design, but the 49mm kit adds a ride height adjustment that can change your bike's handling feel.

Trade-offs to consider

The 41mm cartridge is slightly more expensive (USD 461.49 vs USD 428.99) but does not include ride height adjustability. If you want to fine-tune your bike's stance or cornering balance, the 49mm kit gives you that extra control. Both use linear rate springs that maintain consistent support through the travel, preventing the dive you might experience with stock components.

Decision rules

  • Match the fork diameter: Measure your fork tube diameter or look up your Harley-Davidson Touring model specs. Choose the 41mm cartridge for 41mm forks and the 49mm cartridge for 49mm forks. Double-check your fork size before ordering.
  • Decide on ride height adjustability: If you want to adjust your bike's front ride height for different riding conditions or a custom stance, the 49mm cartridge is the only option that includes this feature.
  • Consider spring weight: Both cartridges are available with different spring weights to match your riding weight and style. Choose the correct spring weight for optimal support and comfort. Select the spring weight during checkout.
