What is a progressive rate spring?

A progressive rate spring starts with a lower spring rate for a softer initial feel, then increases its rate as it compresses. This allows for a comfortable ride over small bumps and provides more support when the suspension is heavily loaded or compressed.

What is the benefit of preventing bottoming out?

Preventing bottoming out means the suspension is not fully compressing to its limit. This protects your shocks and other suspension components from damage and maintains better control of the vehicle during hard braking or when encountering large bumps.

What does the black finish do?

The black finish on these springs is primarily for aesthetics, giving them a clean, stealthy look. It also provides a basic layer of protection against corrosion and minor abrasions.

About this part

Product Details

These Progressive Rear Springs feature a spring rate of 115 pounds per inch at the start of compression and 155 pounds per inch at full compression. This progressive rate design means the spring starts out softer for a more comfortable ride over small bumps and then stiffens up as the suspension compresses further. This helps prevent the rear end from bottoming out during hard braking or when hitting larger impacts.

The black finish on these springs not only looks good but also offers a layer of protection against the elements. They are well-built to handle the demands of daily riding, providing a noticeable improvement in stability and overall ride comfort. You'll find they offer a plush feel over everyday road imperfections while still providing the support needed when you push the bike a little harder.
