The Edelbrock Stage 1 Street supercharger system for 2007–2013 Silverado and Sierra 1500 increases power for Gen IV 4.8L and 5.3L engines (roughly 334 hp/380 lb‑ft and 364 hp/397 lb‑ft at the rear wheels respectively). It uses an Eaton Gen VI 2300 TVS rotor assembly, an integrated bypass valve to reduce parasitic loss, a short, efficient inlet and a high‑capacity air‑to‑water intercooler with a heat exchanger. The supplied tune is intended for otherwise stock vehicles and the system is 50‑state emissions legal.
