At first glance, the shocks look nearly identical, but there are a lot of minor differences that will make a difference in both ride quality, and experience with ownership on the vehicle. On most applications, the Eibach Pro-Truck option can achieve more lift compared to the Fox option, since Eibach is providing a longer shock and spring in their package.
The different valving approaches between the companies are one of the most important distinctions. A digressive valving approach, either through the piston itself, or the shim stack, usually results in tighter handling and performance in the easy stuff, or onroad.
A digressively valved shock will typically respond firmer at the beginning stages of shock travel and loosen up in the more aggressive terrain. A linear valving approach has a more even damping curve that sees more equal force across shock speed and force.
The aluminum body and heat dissipation of the Fox vs the steel body of the Eibach is a slight advantage, and one you will only take advantage of if you’re running long trails in the heat, where shocks can exceed 250-300 degrees.
