Porsche 356 Front Suspension Link Pin Seal
Sold each - 2 required per car

The Porsche 356 front suspension link pin seal is a critical component designed to protect the link pin assembly from dirt, moisture, and debris. Fitted to the front suspension of all Porsche 356 models, this seal helps retain lubrication while preventing premature wear of the king and link pin system — a cornerstone of the 356’s precise and lightweight handling.

Fits:

• Porsche 356 1950-55
• Porsche 356A 1955-59
• Porsche 356B 1959-63
• Porsche 356C 1963-65

Though small, link pin seals play a vital role in suspension longevity. Over time, age, heat cycles, and road contamination cause seals to harden, crack, or shrink, allowing grease to escape and contaminants to enter the suspension joint. Replacing worn seals is essential to maintaining correct steering feel, suspension geometry, and long-term component health on your classic Porsche 356.

What Does a Porsche 356 Link Pin Seal Do?

The front suspension link pin seal sits at the outer ends of the link pins, forming a protective barrier between the suspension joint and the external environment. Its purpose is to:

• Retain grease within the link pin assembly
• Prevent ingress of water, grit, and road debris
• Reduce wear on link pins and bushes
• Maintain smooth, controlled front suspension movement

Without an effective seal, metal-on-metal wear accelerates rapidly, leading to looseness, uneven tyre wear, and compromised steering precision.

Why Do Front Suspension Link Pin Seals Fail?

On Porsche 356 models, link pin seals commonly fail due to:

• Age-related rubber hardening and cracking
• Grease contamination and degradation
• Long-term storage without maintenance
• Exposure to moisture and road debris

Even low-mileage vehicles are prone to seal failure simply due to age. Original or old replacement seals may no longer provide adequate protection, making proactive replacement essential during suspension servicing or restoration work.

When Should You Replace Porsche 356 Link Pin Seals?

You should replace the Porsche 356 front suspension link pin seals when:

• Performing a front suspension rebuild or overhaul
• Replacing link pins, bushes, or king pins
• Grease leakage is visible around the link pin area
• Steering feels vague or inconsistent
• Restoring or recommissioning a long-stored vehicle

Replacing seals early helps prevent costly suspension wear and preserves the original driving characteristics Porsche 356 models are renowned for.
