Fits 1994-2001 Acura Integra GS-R and Type R, 1999-2000 Honda Civic Si, and 1994-1997 Civic del Sol VTEC.

BLOX Racing Lost Motion Assemblies (LMAs) are engineered to replace the aging factory hydraulic-style units found in B-Series and H-Series VTEC cylinder heads. Over time, original hydraulic LMAs often lose their effectiveness, leading to the notorious "VTEC clatter" or valvetrain noise. These BLOX Racing units utilize a modern spring-type design that provides consistent tension against the high-lift rocker arm when VTEC is disengaged, preventing rocker float and ensuring valvetrain stability at high RPM.

  • Eliminates valvetrain noise and ticking common in high-mileage VTEC heads
  • Spring-type design offers superior durability over OEM hydraulic pistons
  • Ensures proper rocker arm alignment and contact during high-RPM operation
  • Critical upgrade for performance camshaft installations and cylinder head rebuilds
  • Direct replacement for factory Honda/Acura components
  • Manufacturer Part Number: BXPT-11300
