DIYers and home mechanics working on suspension upgrades know the frustration of ill-fitting pin spanners and fixed-size wrenches that mar the shock collar finish. This adjustable C-shape coil over spanner wrench is built for anyone who wants a single, reliable tool that handles the full range of shock absorber collar sizes without compromise.\u003c\/p\u003e\n    \u003cp\u003eEach wrench is machined from carbon steel and features a C-shaped jaw that opens to engage the outer collar of coilover shock absorbers. The adjustable design spans a wide size range — from compact 18–22mm collars up to large 220–240mm units — with each variant sized to cover a specific range. Jaw depth and pin engagement are proportioned to the collar diameter, giving you solid torque transfer without rounding edges.\u003c\/p\u003e\n    \u003cp\u003eUse it when setting ride height on a coilover suspension kit, fine-tuning spring preload after a track day, or servicing rear shock assemblies on motorcycles and ATVs. The C-shape profile also makes it a practical choice for adjusting large lock rings on hydraulic cylinders and industrial threaded collars — anywhere a conventional wrench cannot reach around a cylindrical body.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"hdiy-compat\"\u003e\n    \u003cspan class=\"hdiy-compat-icon\"\u003e⚙️\u003c\/span\u003e\n    \u003cstrong\u003eCompatibility:\u003c\/strong\u003e Fits coilover shock absorber collars from 18mm to 240mm.
