Adjustable coilover spanner set with rubber grip — designed for safe, accurate spring preload and suspension adjustments Key benefits Safer grip: Rubber handle increases friction and prevents slipping, protecting your hands and reducing the chance of injury during use. Precise control: Adjustable crescent-style design and front hook engagement let you lock into side holes or slots to avoid slippage and wear while turning threaded collars. Durable construction: Threaded keys and C-shape wrenches are made from high-quality steel with high hardness for long service life. Resistant to corrosion, rust, deformation, and breakage under normal use. Fast identification: Color-matched wrenches make it easy to pick the correct size quickly in a toolbox or on the shop bench. Complete sizing: Multiple wrench sizes and sufficient quantities cover a range of coilover applications and general mechanical tasks. Compatibility and sizes Small wrench: Fits small tension rings on coilovers. Medium wrench: Fits special coilovers including specific models such as KW and HandR. Large wrench: Suitable for some skunks. The set provides a range of sizes to meet different adjustment and maintenance requirements. Practical features Front hook design locks into side holes or slots so the wrench does not slip off the collar during adjustment. High-hardness steel construction minimizes bending and breakage when working on tight threaded collars. Ergonomic rubber handle reduces hand fatigue for repeated adjustments. Typical applications Adjusting spring preload and ride height on coilovers during installation or corner-weighting. Servicing or dialing in KW and HandR coilovers where medium-sized spanners are required. General mechanical maintenance on vehicles and machine tools where C-shaped spanners and threaded keys are used. What you get A set of color-matched, high-quality steel threaded keys and C-shape wrenches in multiple sizes with rubber handles, ready for suspension work, vehicle repair, and mechanical equipment maintenance. Professional, reliable toolset for suspension tuning and mechanical maintenance — built to stay secure on threaded collars and to last through repeated use.
