Bearing & Sleeve for 5.5in Clutchs

The Bearing & Sleeve for 5.5in Clutches is a precision drivetrain component engineered for heavy-duty power transmission in tactical and military vehicle platforms. Built by Quarter Master, a manufacturer with proven track record in high-performance clutch systems, this bearing and sleeve assembly serves as the critical interface between the clutch pressure plate and transmission input shaft. Whether you're operating in law enforcement fleet maintenance, military motor pool operations, or specialized tactical vehicle support, this component ensures reliable engagement under extreme duty cycles and demanding field conditions.

The bearing and sleeve assembly functions as a release mechanism within the 5.5-inch clutch system, allowing smooth disengagement of the transmission when the clutch pedal is depressed. Quarter Master's design uses precision-ground bearing surfaces and hardened steel sleeves to withstand the radial and thrust loads generated during repeated engagement cycles under combat load or high-speed tactical operations. The compact 2.5 x 2 x 2.5-inch profile and 0.63-pound weight reflect optimized engineering for minimal parasitic loss and efficient power delivery, critical specifications for vehicles operating in austere environments where mechanical reliability directly impacts mission success.

Operators and fleet maintenance personnel benefit most from this bearing and sleeve when performing clutch system rebuilds, replacements, or preventive maintenance on vehicles equipped with Quarter Master 5.5-inch clutch platforms. Correct installation requires precise alignment during assembly to ensure bearing preload and sleeve concentricity meet OEM specifications; improper fit can cause premature wear or transmission chatter. This component is compatible with specific vehicle platforms and transmission assemblies that factory-specify the Quarter Master 5.5-inch clutch system, making verification of fitment critical before purchase. Professional installation by certified automotive or fleet technicians is recommended to guarantee optimal performance and longevity in tactical duty applications.
