Collection: GSC Power Division Canada - Authorized Dealer - My Parts Guy

GSC Power-Division specialises in valvetrain and camshafts for boosted four-cylinder and six-cylinder import engines. Its best-known parts are the S1, S2 and S3 camshaft grinds, stainless and Inconel exhaust valves, beehive and dual valve spring kits, titanium retainers and billet valve spring seats. Popular platforms include the Mitsubishi 4G63 and 4B11, Subaru EJ and FA, Honda K-series, Nissan SR20 and VR38, and the Toyota 2JZ. Because higher boost and higher rpm are exactly where stock valvetrain gives up, GSC parts tend to show up on builds targeting reliable power well past factory limits. My Parts Guy ships GSC Power-Division camshafts and valvetrain across Canada in CAD.
