.015 Axle Shim for Baby Bulldog

The .015 Axle Shim for Baby Bulldog from DIVERSIFIED MACHINE is a precision-engineered adjustment component designed for fine-tuning differential carrier bearing preload and pinion depth on Baby Bulldog rear axle assemblies. This shim serves builders, fabricators, and experienced mechanics who demand exact gear mesh geometry and backlash control during axle setup and repair. Proper shimming is critical to maximize gear lifespan, minimize whine and vibration, and ensure reliable power transmission under load.

Manufactured to tight tolerances, the .015 Axle Shim measures precisely 0.25 x 0.25 x 3 inches and weighs a minimal 0.25 pounds, allowing it to stack seamlessly with other shims during assembly. The thin-gauge steel construction maintains consistent thickness under the pressure and thermal cycling encountered in real-world axle operation. A .015-inch thickness increment provides the incremental adjustment needed when dialing in carrier bearing preload or correcting pinion height—critical variables that separate a quiet, long-lasting setup from one prone to bearing failure or gear noise.

This shim is essential for owners building or rebuilding Baby Bulldog axle assemblies, whether for street performance, circle track, or restoration projects where OEM tolerances or wear require adjustment. Installation occurs during carrier bearing cap assembly; stacking multiple shims allows builders to achieve the exact preload specification demanded by the axle design and intended duty cycle. Pairing this shim with quality bearings, proper break-in, and periodic maintenance ensures smooth, durable axle performance for years to come.
