113-301-257 VW Transmission Cradle Mount Bolt - Type 1, 2 & 3

Transmission Carrier Mount Bolt – 113-301-257

The 113-301-257 is an often-overlooked but vital fastener for any vintage VW chassis restoration. Over decades, these bolts are subjected to road salt, moisture, and extreme vibration, often leading to "seizing" in the frame horns. When rebuilding a transmission or replacing mounts, using fresh hardware prevents the risk of bolt failure, which could lead to severe drivetrain misalignment.

This bolt is designed to pass through the transmission cradle (carrier) and thread directly into the frame horns. It is compatible with standard rubber mounts as well as aftermarket urethane or solid performance mounts.

Product Highlights & Features

• High-Grade Steel: Forged to handle the constant shear and tension forces exerted by the engine and transmission.

• Correct Shank Length: Ensures the bolt doesn't bottom out in the frame horn before the carrier is fully tightened.

• Corrosion Protection: Typically finished with a zinc coating to prevent the bolt from bonding to the chassis over time.

Technical Specifications

• Part Number: 113-301-257 (111-301-257/17-2828-7)

• Application: Swing Axle Transmission Carrier

• Location: Rear Frame Horns

• Sold As: Individually (Usually requires two per vehicle)

Installation & Maintenance Tips

• Anti-Seize is Essential: Because these bolts thread into the hollow frame horns, always apply a liberal amount of anti-seize lubricant to the threads before installation to ensure they can be removed in the future.

• Torque to Spec: Refer to your factory service manual for specific torque values. Over-tightening can strip the threads inside the frame horn, which is a very difficult and expensive repair.

• Inspect the Cradle: While the bolts are out, inspect the transmission cradle for cracks around the bolt holes, which is a common failure point on high-mileage vehicles.
