What is the benefit of a progressive spring design?

A progressive spring design offers a dual rate. It starts softer to absorb road imperfections for a more comfortable ride, then gets stiffer as it compresses during cornering or braking, which helps reduce body roll and improve handling.

Do these springs come with everything needed for installation?

These are lowering springs only and are designed as direct replacements for your OEM springs. You will likely need to reuse your existing hardware and potentially other suspension components for installation. Refer to the manufacturer's installation instructions for details.

What does the lifetime warranty against breaking cover?

The lifetime warranty against breaking covers the springs themselves from fracturing or snapping under normal use. It ensures that the structural integrity of the spring is protected for as long as you own the vehicle.

About this part

Product Details

These AST lowering springs are cold-coiled on Wafios coiling machines, a detail that speaks to their well-built nature. They're designed to replace your Nissan 309's factory springs directly, offering a way to lower your vehicle's center of gravity by about 35mm. This change can lead to improved handling characteristics without sacrificing too much of the comfortable ride you're used to from the original equipment.

The progressive design of these springs is key to balancing a lower stance with everyday drivability. It means they offer a softer initial spring rate for comfort over bumps, then stiffen up as they compress during cornering or hard braking. This approach helps reduce body roll and can make your car feel more responsive on the road. They are built to be a direct fit, meaning installation should be straightforward for someone familiar with suspension work.

With a lifetime warranty against breaking, AST stands behind the durability of these springs. They are a solid option if you're looking to give your 1986-1993 Nissan 309 a lower profile and a more engaging feel on the road.
