QA1 coil over wrenches fit most coil over shocks. They offer enough leverage to turn most spring seats and are small enough to fit in your back pocket. The ratchet spanner wrench is great for tight working conditions and can be used on all QA1 drag and street shocks except Steelers/Economy Steelers. Kit includes two wrenches for use with a 3/8” drive ratchet that fit either the spring seat adjuster nut or lock nut.
