If you want more power out of your Gen III/IV LS engine, the GTA Series of street performance camshafts from Straub Technologies is the answer. Our GTA camshafts will boost the power of your LS like no other hydraulic roller cam. These cams have been engineered to feed the demand of your LS based on CID and cylinder head. Your CID and desired RPM range sets the demand of the engine. The cylinder head, based on its flow characteristics, will deliver the air and fuel. Since there are multiple options in heads with different flow rates, you need a camshaft based on what the heads can supply. The GTA series of camshafts makes this easy. You select your engine and cylinder head combination and we supply the camshaft. Straub Tech takes the guess-work out of camshaft selection. Straub Tech camshafts are proven world-wide by customers who crave maximum power. These cams all but guarantee the performance you're looking to get out of your LS. Customers report easier starting, a much more broad, usable power-band, greatly improved throttle response, faster spooling of turbos, and lower EGTs. Dyno tests have consistently shown a greater power gain under the curve compared to the competition.
