What is adjustable spring preload?

Adjustable spring preload lets you change the tension on the shock spring. This allows you to fine-tune the suspension's stiffness to better handle different weights or riding conditions, like carrying a heavy load or plowing snow.

What is the purpose of the Shock "Sox"?

The included Shock "Sox" is a protective cover that slides over the spring and shock body. It helps keep dirt, mud, and debris away from the spring and the preload adjustment mechanism, keeping them cleaner and easier to operate.

Are these shocks designed for specific ATV types?

Yes, the 512 Series shocks were specifically developed for utility ATVs. They are built to handle the heavier loads and rougher terrain often encountered with work-oriented vehicles.

Product Details

Progressive is known for making aftermarket suspension components, and their 512 Series shocks are a prime example of their work for utility ATVs. These shocks are built to handle the demands of a workhorse vehicle, offering a significant upgrade over stock suspension. They've been developed through extensive research and testing to give you a better ride, whether you're on the trail or hauling a load.

What sets these shocks apart is the attention to detail for utility use. You get improved spring rates that help keep your ATV stable when carrying heavy loads or navigating rough terrain. The increased length also means more suspension travel and a bit more ground clearance, which is always helpful. Plus, they come with adjustable spring preload, so you can easily dial in the suspension to match what you're doing, like when you're mounting a plow or carrying a heavy bale of hay.

To help keep these shocks working their best, they include Shock "Sox." This cover helps keep dirt and mud away from the spring and makes sure the adjustment mechanisms stay clean and easy to use.
