Transmission Mount Bolt Washer, Sold Each

OVERVIEW

When it comes to the structural integrity of your air-cooled Volkswagen''s drivetrain, no detail is too small to overlook. The EMPI Transmission Mount Bolt and Washer kit is a critical component designed to provide a secure, rock-solid connection between your transmission mount and the chassis yoke. Over decades of operation, original factory hardware often suffers from metal fatigue, cross-threading, or severe corrosion due to exposure to the elements and road grime. A loose or failing transmission bolt can lead to excessive drivetrain vibration, poor shifting alignment, and even catastrophic failure of the mounting cradle. By replacing your aging hardware with these high-strength EMPI components, you ensure that your transaxle remains properly indexed, protecting your expensive gearbox and ensuring smooth power delivery to the wheels.

This replacement bolt and washer set is engineered specifically for swing axle transmission mounts, making it an essential item for both stock restorations and high-performance off-road builds. Whether you are refreshing a daily driver Beetle or assembling a rugged sand rail, the precision-cut threads and included lock washer provide the clamping force necessary to withstand the high-torque environment of a VW flat-four engine. These bolts are compatible with standard factory cradles as well as heavy-duty performance mounts, offering the versatility needed for any Type 1 based project. Don''t risk your build by reusing rounded-off or weakened hardware; installing fresh, zinc-plated bolts is the professional way to complete your transmission installation and maintain the longevity of your rear suspension components.

PRO TIPS

1. Always Use a Torque Wrench

One of the most common mistakes when installing transmission hardware is over-tightening, which can strip the threads inside the cast-iron transmission yoke. Conversely, under-tightening can lead to the bolt backing out due to engine vibration. Always refer to your factory service manual for the exact torque specification. We recommend applying a small amount of medium-strength (blue) thread-locking compound to the threads to ensure the bolt stays put, even under the harsh vibrations of an air-cooled engine.

2. Inspect the Yoke Threads Thoroughly

Before installing your new EMPI bolt, take a moment to clean the internal threads of the transmission yoke using a wire brush or a thread chaser. Since these bolts live in a high-moisture area near the ground, the internal threads often collect grit and old grease. If the threads in the yoke are damaged, a new bolt will not provide the necessary holding power. Cleaning the threads ensures a smooth installation and prevents the new bolt from galling or seizing during the torquing process.

3. Replace in Pairs for Consistency

While these bolts are sold individually for your convenience, we strongly recommend replacing all transmission mount bolts at the same time. Hardware of the same age typically experiences similar levels of stress and fatigue. By installing a complete set of new EMPI bolts, you ensure uniform clamping pressure across the entire mounting cradle. This prevents uneven loading on the rubber mounts, which helps reduce cabin noise and prevents premature wear of the transmission mount bushings.
