Weighing 1 lbs (0.5 kg) 15 oz (425.2 g), this valve spring compressor compresses springs and removes keepers directly on the engine to eliminate the need for cylinder head removal. The adjustable cam action allows for rapid operation because the tool does not require readjustment after each spring. This design simplifies overhead valve maintenance by maintaining consistent settings throughout the job.
