This automotive component grouping enhances engine performance in vehicles manufactured by Chrysler and its associated brands. It typically includes a camshaft, valve lifters, valve springs, and related hardware designed to optimize the engine’s valve timing. An example would be a kit specifically engineered to improve horsepower and torque in a Dodge Challenger equipped with a Hemi engine.
Its significance lies in its ability to alter the engine’s power band, potentially increasing output at higher RPMs. The benefits extend to improved throttle response and overall engine efficiency. Historically, modifications to valve timing have been a common method for extracting more performance from internal combustion engines, with the availability of pre-packaged kits simplifying the upgrade process for enthusiasts and professional mechanics alike.
