The Front Engine Poly Snub Mount (Part Number: 22501) is a critical rubber component designed to stabilize the powertrain in classic Volkswagen Mk1 and Mk2 models. This specific mount acts as a “bump stop” for the engine, preventing excessive front-to-back rocking during acceleration and braking.
Poly Snob Mount Specifications and Function
-
Role: This mount serves as a torque vibrator damper that absorbs engine movement and prevents it from transferring into the chassis.
-
Material: It is constructed from high-quality, durable rubber designed to withstand the heat and stress of the engine bay.
-
Installation: It slides onto the front engine mount bracket and fits into the cup located on the front core support of the vehicle.
-
Performance Impact: Replacing a worn or dry-rotted snub stop restores a “tight” feel to the drivetrain and protects other more expensive engine mounts from over-extending.

Signs Your Snub Mount Needs Replacement
Because this part is made of rubber, it eventually hardens, cracks, or compresses until it no longer fills the mounting cup. Look for these symptoms:
-
A noticeable “thud” when letting off the gas or shifting gears. For example, if you have a lot of movement when letting out the clutch, this could be bad.
-
Visible cracking or missing chunks of rubber when inspecting the front of the engine.
-
Excessive engine movement when revving the motor while the vehicle is stationary.
