About This Product

S&S electric compression release kit. Fits high-compression or big-bore Harley-Davidson engines. The solenoids crack the valves open during cranking to drop cylinder pressure. Your starter motor and battery do less work. The components live inside the cylinder head and see plenty of heat. You will want this on any large-bore performance build. Sold as a kit.

Manufacturer part number: 90-4915.
