Construction & Design:
Brian Tooley Racing meticulously designs and manufactures the Stage 4 camshaft in-house, focusing on precision lobe profiles that balance aggressive performance with mechanical stability. The camshaft lobes are engineered to optimize valve timing and lift, delivering enhanced airflow and combustion efficiency. High-quality materials and rigorous testing protocols, including spintron and dyno validation, ensure the camshaft withstands the stresses of high RPM operation while maintaining long-term durability.
The camshaft’s design also accounts for the heavy OEM valves and the increased RPM potential, necessitating the use of upgraded valve springs and hardened pushrods in power-adder applications to maintain valve control and prevent component wear.
Performance & Sound
The Stage 4 camshaft produces a substantial power increase, with dyno-tested gains of up to 83 horsepower and 72 lb-ft of torque at 6000 RPM. It enables the engine to pull strongly beyond 7100 RPM, expanding the powerband by approximately 1900 RPM compared to stock. This camshaft delivers an aggressive idle characterized by a pronounced exhaust note, reflecting its performance-oriented profile. When paired with supporting modifications such as long-tube headers, E85 fuel, and upgraded valve springs, the Stage 4 camshaft transforms the 5.7L HEMI into a high-revving powerhouse suitable for spirited driving and performance builds.
Installation & Fitment:
The Stage 4 camshaft is compatible with a wide range of 5.7L HEMI-equipped vehicles, including:
- 2009–2024 Chrysler 300 5.7L HEMI
- 2009–2023 Dodge Challenger 5.7L HEMI
- 2009–2023 Dodge Charger 5.7L HEMI
- 2009–2025 Dodge Durango 5.7L HEMI
- 2009–2010 Dodge Ram 5.7L HEMI
- 2011–2024 Ram 5.7L HEMI
- 2009–2021 Jeep Grand Cherokee 5.7L HEMI
Installation requires the included VVT cam phaser lock-out kit to disable variable valve timing, ensuring proper camshaft function. Additionally, upgraded valve springs and non-MDS lifters are mandatory to handle the increased lift and RPM range. For best results, a professional tune is recommended to optimize engine calibration and fully realize the camshaft’s performance potential. The use of an aftermarket torque converter is also advised to maintain drivability and maximize power delivery.
