GSC P-D Mitsubishi 4G63T Evo 1-3 / 90-99 DSM R4 Camshafts 295/310 Billet (Drag Race Engine Only)

These GSC Power Division R4 camshafts are built from solid billet material, a strong foundation for serious drag racing builds on the Mitsubishi 4G63T engine found in Evo 1-3 and 90-99 DSM models. With a duration of 295 degrees on the intake and 310 degrees on the exhaust, these cams are specifically tuned for maximum power output at high RPMs, making them ideal for vehicles solely intended for the drag strip. The aggressive ramp rates and lift profiles are designed to work together to ensure optimal valve timing and airflow during those critical moments of acceleration.

The choice of billet material means these camshafts are well-built and can withstand the extreme stresses of a dedicated drag race engine. This isn't a street cam; it's built for competition where every bit of performance counts. The R4 profile is a popular choice for builders looking to extract the most power from their 4G63T, especially when paired with other performance engine components. Expect a significant change in your engine's powerband, with peak performance occurring much higher in the RPM range than stock.

Because these camshafts are designed for maximum performance in a competition environment, they are not CARB approved and cannot be shipped to California. Ensure your build is focused on drag racing to get the most out of this specialized component. Always refer to the manufacturer's installation guide for proper setup and break-in procedures to ensure longevity and performance.
