HCT features a self-contained hydraulic cartridge within a thick wall lifter body. With reduced oil volume, the hydraulic cartridge is less affected by oil aeration. In turn, the Hydraulic Roller Lifters offer the most consistent bleed rates between each lifter on the market. In addition to a precision-controlled bleed down rate, the Hydraulic Roller Lifters also reduce startup noise significantly and promote top performance at high RPM. The cartridge design allows for a stiff lifter body, dramatically reducing body distortion and further ensuring consistent hydraulic performance.
