What is a progressive rate spring?

A progressive rate spring has a spring rate that changes as it is compressed. It starts with a softer rate for initial engagement and becomes stiffer as it compresses further. This allows for a smoother initial ride while still providing support under heavier loads or impacts.

What does this bump stop spring pack do?

This pack includes progressive rate springs that work with your existing bump stops. They are designed to improve the suspension's response by absorbing impacts more smoothly and reducing harshness, especially when the suspension is compressed.

Does this kit include the entire bump stop assembly?

This product includes the progressive rate bump stop springs. It is designed to work with your vehicle's existing bump stop components.

About this part

Product Details

This Carli Bump Drop Full Progressive Spring Pack for the rear of your 2005-2016 Ford F250 or F350 Super Duty includes the progressive rate bump stop springs. These springs are designed to work with your existing bump stop system to provide a more controlled and comfortable suspension response.

The progressive rate design means these springs offer a softer initial engagement that gradually stiffens as they compress. This helps to absorb impacts more smoothly, reducing harshness over bumps and during compression events. This updated spring rate helps to manage the suspension's reaction, especially when carrying loads or driving over uneven terrain. The pack is well-built to handle the demands of a Super Duty truck.
