What is the lift height difference between the Trail Boss/AT4 and standard models?

These coilovers provide a 3.5-inch lift for standard Silverado 1500 and Sierra 1500 models. For models equipped with the Trail Boss or AT4 suspension, they offer a 1.5-inch lift.

Are these coilovers a direct bolt-on replacement for the factory shocks?

Yes, these FOX coilovers are designed as a direct bolt-on upgrade for the factory front shocks and springs on compatible Silverado 1500 and Sierra 1500 models.

What is the benefit of the external reservoir system?

The external reservoir system on these coilovers helps to increase the shock's oil capacity and surface area, which aids in dissipating heat more effectively. This leads to more consistent damping performance, especially during demanding use or over rough terrain.

Product Details

If you're looking to give your 2019-2025 Chevrolet Silverado 1500 or GMC Sierra 1500 a significant suspension upgrade, these FOX 2.5 Performance Elite Series front coilovers are a solid choice. Developed with technology from off-road racing, these shocks are built to handle tough terrain while providing a more comfortable ride on the street. They are specifically tuned for your truck, meaning the valving is set up to work best with the weight and suspension geometry of the Silverado 1500 and Sierra 1500.

These coilovers feature an aluminum body, which helps dissipate heat more effectively than steel, especially important during extended use or aggressive driving. The external reservoir system further aids in cooling, keeping the shock oil at optimal temperatures for consistent damping performance. The components are CNC machined from aluminum and then black anodized for durability and a clean look. This kit offers a 3.5-inch lift for models without the Trail Boss or AT4 packages, and a 1.5-inch lift for those equipped with the Trail Boss or AT4 suspension.

When installing these coilovers, you'll want to refer to the manufacturer's instructions for the specific lift height adjustments based on your truck's configuration. This upgrade is designed to bolt on directly to your vehicle, replacing the factory front shocks and springs.
