KS LEV/LEV Ci Oil Pressure Cartridge

If your post is sagging, failing to return to full extension, or feels sluggish despite proper cable tension, the internal cartridge is likely worn out. Replacing the cartridge is the standard fix for restoring that factory-fresh, smooth action.

This specific cartridge is designed for the LEV and LEV Ci models with a 125mm drop. It is not a universal part, so you must verify your specific post model and drop length before purchasing to ensure a proper fit.

Yes, this is a serviceable part designed for home mechanics. You will need basic bike tools and a bit of patience, but the process is straightforward if you follow the official KS service guide for your specific post model.

This product is the sealed cartridge unit itself. It does not typically include external seals, bushings, or fresh suspension fluid, so you should check if your post requires a full service kit or additional maintenance supplies before you begin the installation.

OEM versions of KS posts sometimes feature slight variations in internal dimensions or threading compared to the aftermarket versions. Always double-check your post's serial number or specific branding against the manufacturer's compatibility charts to avoid fitment issues.
