Chain tensioner blade.
The chain tensioner blade (96410504302) is an OE-Match replacement built to Porsche’s original specifications. It ensures proper timing chain tension, smooth operation, and reduced noise and wear within the engine’s timing system.
Fits left or right side, Sold each.

Fits:
Porsche 964 1989 - 1994
Porsche 993 1994 - 1998

Diagram Ref 13

The tensioner blade maintains proper tension on the timing chain, keeping it securely in place as it runs between the camshaft and crankshaft sprockets. By guiding chain movement, it ensures smooth operation, accurate valve timing, and reduced friction and wear. It also minimizes chain noise, helping the engine run quietly and efficiently.

The tensioner blade is located inside the timing chain assembly. It is mounted against the chain path, where it works with the hydraulic chain tensioner to keep the chain properly aligned and tensioned throughout all engine speeds and loads.

Over time, chain tensioner blades can wear, crack, or deform due to constant stress, heat, and oil exposure. A failing blade may cause the timing chain to loosen, rattle, or fall out of alignment. This can result in inaccurate timing, loss of performance, or even major engine damage. Installing an replacement restores the correct fit and function. Ensures long-term reliability, smoother operation, and protection of engine health.

About Chains & Tensioners

Precision Timing Chains & Tensioners – Engine Synchronisation and Reliability for Porsche Models

The timing chain system is one of the most critical components of a Porsche engine, ensuring perfect synchronisation between the crankshaft and camshafts. This precise coordination allows valves to open and close at the right moment, maintaining smooth power delivery, fuel efficiency, and long-term engine health.

At Design911, we supply a comprehensive range of precision-engineered timing chains, guides, and hydraulic tensioners designed to meet or exceed manufacturer performance standards. Each component is manufactured from high-strength materials for exceptional wear resistance and durability — vital for high-revving, performance-oriented Porsche engines.

What Do Timing Chains and Tensioners Do?

A timing chain connects the crankshaft to the camshafts, ensuring accurate valve timing. The tensioner keeps the chain taut to prevent slack, vibration, or noise, maintaining precise timing under all load conditions.

Core Functions:

  • Synchronise engine timing between the camshaft and crankshaft.
  • Maintain valve timing accuracy for optimal combustion and power.
  • Prevent chain slack and noise through hydraulic or spring-loaded tensioning.
  • Ensure long-term reliability in both performance and everyday driving.

Together, these components preserve the exacting standards of Porsche engine operation — vital for both power and longevity.

Why Do Timing Chains and Tensioners Fail?

Over time, wear, oil degradation, and heat cycles can cause timing components to deteriorate. When neglected, they may stretch, seize, or lose tension — leading to severe engine damage.

Common Causes of Failure Include:

  • Chain stretch or elongation, resulting in timing misalignment.
  • Worn or leaking hydraulic tensioners, causing chain rattle on start-up.
  • Contaminated or degraded engine oil, accelerating wear.
  • Broken chain guides from heat stress or material fatigue.
  • Insufficient oil pressure, reducing hydraulic tensioner performance.

A failing timing chain system can lead to poor performance, rough idling, check-engine lights, or — in extreme cases — catastrophic valve-to-piston contact.

Why Replace with Performance-Grade Timing Components?

Replacing aging timing components with manufacturer-quality parts ensures reliable valve timing, smoother operation, and peace of mind.

Key Benefits:

  • Restores precise valve timing for peak performance and efficiency.
  • Prevents engine noise and vibration caused by chain slack.
  • Protects against catastrophic engine damage due to chain failure.
  • Constructed from heat-treated, high-grade steel for long service life.
  • Engineered to match original timing profiles for Porsche engines.
  • Perfect fitment for classic air-cooled and modern water-cooled models.

Whether performing preventive maintenance or a complete rebuild, these timing chains and tensioners deliver race-ready reliability with road-tested durability.

Highlights:

  • Precision-engineered timing chains, guides, and tensioners for Porsche engines.
  • Restores timing accuracy and eliminates start-up rattle or misfire issues.
  • Built from heat-treated alloy steel for maximum longevity.
  • Hydraulic and mechanical tensioners available for various Porsche models.
  • Ideal for performance rebuilds and preventative maintenance.
  • Compatible with air-cooled and water-cooled Porsche engines.
