This aluminum spring seat fits between upper and lower 60mm springs to "join" them together. Typically you would have a main spring on top and a tender or helper spring on the bottom (or vice-versa). The spring joiner, or locator ring, fits between the springs with a retaining lip on the inside. We like this design better than an outside spring joiner because it's lighter and there's no material sitting on the outside where a tire might come in contact with it. These are priced per each.

The most popular spring in H&R's line-up, Sport Springs will lower your vehicle an average of 1.1 inches for a lower center of gravity, improved handling, and a more aggressive appearance. Sport springs feature a spring rate that is firmer than that of the OE spring but is still comfortable enough for daily use. Sport springs are an excellent choice for street and occasional track use.

Why a strut nut socket? To secure shocks and struts to their mounts, the retaining nut must be torqued to its proper specification using a torque wrench. Strut nut sockets allow for the use of a 21mm wrench to hold the damper shaft allowing you to achieve proper torque. An improper torque value may result in premature mount failure - or worse.
