What is the main benefit of the 412 Series shocks?

The main benefit is improved suspension performance with smooth, consistent damping. The adjustable preload allows you to fine-tune the ride for your specific needs and riding style.

Are these shocks difficult to install?

Installation typically involves removing the old shocks and bolting these in place. It's a common DIY job for many Harley owners, but refer to your motorcycle's service manual for specific procedures.

What does 'progressive rate springs' mean?

Progressive rate springs get stiffer as they are compressed. This means they offer a softer initial ride for small bumps but become firmer under heavier loads or larger impacts, providing a good balance.

Product Details

If you're looking to improve your Harley-Davidson's ride quality, these Progressive 412 Series shocks are a solid option. They're designed to fit a wide range of Harley models, from the Electra Glide Classic to the Softail Standard, offering a noticeable upgrade over stock suspension. These shocks do the job of smoothing out bumps and keeping your ride consistent, whether you're cruising around town or hitting the open road.

What makes these shocks work well is their well-built, doublewall steel body construction. Inside, they're charged with high-pressure gas and feature multi-stage valving that responds to speed, ensuring consistent damping performance. You can also fine-tune your ride using the five-position cam-style preload adjuster. This lets you dial in the suspension to match your weight and riding style, making them a versatile choice for many riders.

These particular shocks come in a 11.0-inch length with a black finish, and they use progressive rate springs. Progressive offers different spring rates and finishes on other 412 models, but this setup is a popular choice for a balanced ride.
