Bert Trans Ball Spline Kit 1/2in 12pk

The Bert Trans Ball Spline Kit 1/2in 12pk from Allstar Performance is engineered specifically for builders and mechanics working with Bert transmission assemblies. This set of 12 steel ball splines serves as a critical wear component in high-performance and racing transmissions where smooth gear engagement and power transfer are non-negotiable. Whether you're rebuilding a transmission, replacing worn spline balls, or performing preventive maintenance on a competition or street-driven vehicle, this kit provides the precision balls required to restore proper mesh and reduce gear noise during shifting.

Each ball features a 1/2-inch outer diameter and is manufactured from hardened steel in natural finish, designed to withstand the repetitive shear forces and high rotational speeds typical in Bert transmission operation. The ball spline geometry allows controlled radial engagement between input and output shafts, enabling torque transfer while accommodating slight misalignment—a design philosophy that minimizes binding and extends component lifespan under load. The 12-piece quantity in this kit covers multiple spline positions or provides a complete replacement set for full transmission servicing, ensuring you have adequate inventory for the job at hand without unnecessary oversupply.

This kit is ideal for transmission rebuilders, performance shops, and serious enthusiasts who demand OEM-quality replacement components for Bert transmission systems. Installation involves careful placement within the transmission case according to manufacturer torque and positioning specifications—precision work that rewards attention to detail with smooth shifts and reliable power delivery. Verify your specific Bert transmission model and spline cavity count before ordering to ensure proper fit and complete coverage of all engagement points.
