A strut that came without a spring perch cannot carry a coil-over spring, and there is no safe way to improvise one. This kit adds the threaded sleeve, adjuster nut and spring seats sized for QA1's HD, HS and HR series struts, which turns a fixed strut into a ride-height adjustable coil-over.

- Converts a QA1 HD, HS or HR series strut to a coil-over.
- Not compatible with HX605, HX607 or HX701 struts.
- Sized for a 2.500 in. inside diameter coil-over spring.
- Threaded spring seat adjuster nut sets ride height.
- Spring seats included.
- Machined from aluminum with a black anodized finish.
- Installs without modification to the strut.
- Coil spring and strut are not included.
