Street HD Hydraulic Bearing GM 1.375 Collar

The Street HD Hydraulic Bearing GM 1.375 Collar from RAM CLUTCH is a precision release bearing assembly engineered for high-performance street and strip driving applications. This component handles the critical job of hydraulic clutch actuation, transferring pressure from your master cylinder to the clutch fork with reliability and consistency. Whether you're building a restomod Chevy small-block, upgrading a modern LS platform, or retrofitting a hydraulic clutch system into a classic muscle car, this bearing collar serves as the mechanical interface between your hydraulic system and clutch engagement. It's designed for drivers who demand durability and smooth clutch modulation under repeated full-throttle load cycles.

Built with a 1.375-inch diameter collar specification, the Street HD Hydraulic Bearing features a heavy-duty sealed bearing core that resists contamination and extends service life compared to unsealed alternatives. The bearing race is manufactured to tight tolerances, ensuring zero runout and minimal friction during clutch actuation cycles. RAM CLUTCH designs this assembly with a reinforced collar body that resists deformation under sustained pressure spikes, critical when running aggressive dual-disc or multi-plate clutch systems. The sealed design protects against water ingress and abrasive particles that accumulate in engine bays, particularly important for vehicles exposed to track conditions, rain, or salt environments. Weighing 1.43 pounds, it integrates seamlessly into most hydraulic clutch bellhousing configurations without requiring frame modifications.

This bearing collar is ideal for Chevrolet small-block and big-block engines using hydraulic clutch systems, as well as aftermarket LS swap builds that retain OEM or performance hydraulic actuation. Installation requires basic mechanical knowledge—the collar bolts to the bellhousing with standard fasteners and connects to your hydraulic line via the release cylinder. Compatibility spans most GM-pattern bellhousings and works with both street and competition clutches rated for 1.375-inch bore diameter specifications. For hot rodders, street racers, and restoration enthusiasts building reliable, drivable vehicles, this bearing collar provides the durability needed to handle repeated launches and sustained highway driving without premature wear or chatter.
