Bilstein front shock absorber gland nut tool, Max. Drehmoment, 140 Nm, MS 08/6. This tool allows you to remove the large gland nut which holds the shock insert inside the strut assembly. Just place your strut assembly in a vice, slide the wrench over the strut allowing the two tabs to interlock the opening on the gland nut, attach any 1/2 drive ratchet or torque wrench and crack the nut loose. Works on both internally and externally threaded strut bodies.
