What the AI looks for in Automotive Performance Shock Cartridges
- Housing type
- Cartridges only fit serviceable strut housings with a removable gland nut, or sealed housings you are prepared to cut open. Many modern struts are sealed and must be replaced complete.
- Length for ride height
- Use shortened cartridges when running lowering springs. Standard-length inserts bottom out on lowered cars.
- Gland nut and fit
- Confirm the housing's inner diameter and the gland nut thread, or that a new nut is supplied. A loose cartridge rattles and damages the housing.
Brands that matter
- Koni: Adjustable inserts for many classic MacPherson strut cars.
- Bilstein: Monotube inserts for a range of European and performance applications.
- KYB: Cartridges for some older strut designs.
What to avoid
- Cutting a sealed strut housing without the correct cutter and a cartridge confirmed to fit.
- Mixing worn and new cartridges across one axle.
Questions
Can I put a cartridge in any strut?
No. It must be a housing designed for inserts, or one that can be opened. Otherwise you need a complete strut.
