What is the purpose of a 'high travel' spring?

A high travel spring is designed to compress and extend over a greater range of motion compared to a standard spring. This allows for more suspension travel, which can improve ride comfort over uneven surfaces and enhance handling by keeping the tire in contact with the road.

What does the 'pigtail' end refer to on this spring?

The 'pigtail' end is a common design for coilover springs where the end of the spring is coiled into a loop or 'pigtail'. This shape is designed to fit securely into the spring perch or mounting hardware of a coilover shock absorber, preventing it from shifting or coming loose.

What is the benefit of the lifetime guarantee on this spring?

The lifetime guarantee ensures that the spring will maintain its original free height within 2% for the life of the product. This means you can expect consistent spring performance and ride height over many years, without the spring sagging significantly.
