What does 'set to block' mean for these springs?

Being 'set to block' means the spring has undergone a process to pre-compress it. This ensures that after installation, the spring will settle to the correct ride height and maintain it over time, preventing sagging.

Does this spring come with any hardware?

This product is for a single front spring only. Installation hardware such as isolators or retainers are typically reused from the original spring or purchased separately.

What is the benefit of using Eibach springs?

Eibach uses carefully selected spring steels and advanced manufacturing processes, including CNC winding, heat treatment, and shot peening. This results in a durable and stable spring designed to maintain your vehicle's correct ride height.

About this part

Product Details

If you're looking to replace a worn-out front spring on your 2015-2020 Ford F-150 4WD with the 3.5L EcoBoost or 5.0L V8 engine, this Eibach single front spring is a solid option. It's designed to restore your truck's ride height and handling characteristics.

Eibach starts with carefully selected spring steels, wound on advanced CNC machines for precise dimensions. They then treat each spring with heat treatment, shot peening, and a durable powder coating for long-lasting stability and corrosion resistance. This process ensures the spring is set to block, meaning it will maintain the correct ride height for many miles after installation.
