Direct Slider Dog Tooth Spline Oversize

The Direct Slider Dog Tooth Spline Oversize from BERT TRANSMISSIONS is a precision internal transmission component designed for high-performance manual and automatic transmission builds. This oversize dog tooth spline slider is tailored for builders and mechanics who require enhanced torque capacity and shift reliability in various applications, including competition, street rod, and heavy-duty racing.

Engineered to improve engagement surfaces and load distribution, this component is essential for custom transmission assemblies where standard internals may not suffice. The aggressive tooth geometry of the dog tooth spline design minimizes rotational play, preventing gear rattle and ensuring smooth synchronization during gear changes. The oversize profile increases the bearing surface area, distributing clamping forces across multiple engagement points to enhance durability.

Transmission builders, engine builders, and mechanics working on vintage restorations or constructing pro-street and drag racing gearboxes will find this slider indispensable for its reliability under demanding conditions. Proper installation requires alignment with mating shafts to ensure optimal performance and longevity.
