What is the main benefit of the 5-position preload adjuster?

The 5-position cam-style preload adjuster allows you to easily change the spring tension. This lets you fine-tune the ride for your specific weight and riding conditions, whether you're riding solo or with a passenger.

Are these shocks nitrogen charged?

Yes, these shocks are high-pressure gas charged, typically with nitrogen. This helps maintain consistent damping performance by preventing oil and gas from mixing, even under demanding use.

What is the difference between standard and heavy-duty springs?

While this specific model comes with standard progressive rate springs, Progressive offers Heavy-Duty spring options for select applications. Heavy-Duty springs are generally recommended for heavier riders or for carrying significant loads.

Product Details

When you're looking to dial in the ride on your Harley-Davidson, especially models like the Electra Glide or Softail Standard, a good set of shocks makes all the difference. These 12-inch chrome 412 Series shocks from Progressive are built to give you a smoother, more controlled feel on the road.

They feature a doublewall steel body for durability and are charged with high-pressure gas to ensure the damping stays consistent, no matter how hard you ride. You can easily adjust the spring preload using the five-position cam-style adjuster to fine-tune the ride for your weight and riding style, whether you're cruising solo or carrying a passenger. The progressive rate springs help provide a comfortable ride across a range of conditions.

These shocks are a solid option for many Harley-Davidson models from the 70s through the 80s. If you're looking for a well-built shock that offers adjustability and improved performance over stock, these are worth considering.
