Shock Preload Spanner Wrench | 50mm C-Hook 55-62mm Collars

Stop fighting your suspension with the wrong tool. This 50mm C-Hook Shock Spanner Wrench is purpose-built for adjusting coil-over shock spring preload collars and round nuts from 55mm to 62mm in diameter. The laser-cut 50mm inner arc seats firmly on the collar without slipping, so you can dial in your preload precisely — whether you're setting up for a track day or tuning ride height in the parking lot.
