The Rotor LH 8 Bolt 36 Vane 1.25x11.75 from Allstar Performance is a precision-engineered hydraulic pump rotor designed for high-performance racing and engine modification applications. This left-hand (LH) rotor is a critical component in centrifugal pump assemblies, enabling efficient fluid circulation under extreme operating conditions.
With a bore diameter of 1.25 inches and a rotor diameter of 11.75 inches, this rotor features 36 vanes that contribute to its performance. The 8-bolt attachment pattern ensures compatibility with standard Allstar pump housings and mounting plates commonly used in racing cooling systems. Its precision-cast construction maintains tight tolerances, which are essential for optimal pump efficiency across varying engine speeds.
Builders working on competition engines, whether small-block or big-block Chevrolet, Ford, or Mopar, will find this rotor beneficial for their high-performance applications. The rotor's weight of 11.47 lbs is designed to balance centrifugal forces, reducing vibration and extending bearing life in high-RPM environments.
