Built with ease of use in mind, this Valve Spring Compressor features a tapered design to aid in installation of keeper, along with aluminum construction so your pencil magnet doesn't stick to the tool. The bridge places the threaded stud directly over the center line of the injector bore. This applies equal force on all four valve springs.
