      McLeod 1300-Series Hydraulic Throwout Bearings are high-quality replacements for factory bearing retainers, providing precision clutch actuation. They are designed for applications where the "A" dimension (bell housing rear surface to the top of the pressure plate release fingers) is less than 3 inches. Each throwout bearing features a hard-anodized billet aluminum body, elbow swivel fittings, and high-pressure stainless steel braided lines for strength and durability.

      Upgrade your clutch system with confidence using McLeod Bolt-On Hydraulic Throwout Bearings — a precision-engineered solution designed to deliver smoother shifts, improved clutch modulation, and long-lasting performance. Whether you’re building a high-power street car, restoring a classic, or prepping a competition machine, these hydraulic throwout bearings simplify installation and enhance drivability compared to traditional mechanical linkage systems.

      McLeod hydraulic throwout bearing units eliminate the need for external clutch linkage, providing a clean, direct interface between your clutch pedal and pressure plate. This means less drivetrain lash, more consistent pedal feel, and reduced maintenance over time. Their bolt-on design makes them an ideal upgrade for performance enthusiasts who want professional-grade results without complicated modifications or fabrication.

      One of the biggest advantages of a McLeod hydraulic throwout bearing is the improved clutch engagement it delivers. By centralizing actuation at the bearing, these assemblies reduce wasted motion and help ensure smooth clutch release — especially helpful in high-power, high-load applications where precise control matters most. Whether you’re launching hard at the strip, crawling through traffic, or shifting quickly on the street, this design enhances clutch feel and response with every gear change.

      Built with durable materials and engineered to meet McLeod’s strict quality standards, the mcleod hydraulic throwout bearing holds up to demanding use and helps extend the life of your clutch components. Installation is straightforward with bolt-on compatibility for many popular transmissions and bellhousing patterns, making it accessible to experienced DIY mechanics and professional builders alike.

      If you’re looking for a clutch actuation upgrade that offers smoother operation, reliable performance, and a modern feel, the McLeod throwout bearing is a smart investment — helping you get more out of your drivetrain with less fuss and greater confidence behind the wheel.
