Chains & Tensioners
To help remove all the balance shaft belt and ancillary
products on 944/968 which is only way to make the engine run smoother (After
you’ve removed that stuff these bungs to plug up the holes on the engine, so it
does leak from where the shafts used to be).
So, engine will still run without all that balance shaft
belt and ancillary, maybe a bit rougher but will save a bit of engine power not
having to drive all that stuff and engine weight. (Crankshaft/Camshaft timing
is on a separate timing belt on 944/968)

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.
