Information
High-quality replacement timing belt tensioner damper. Manufactured to meet or exceed Porsche’s original specifications, including dimensions, materials, and spring/damping rates. Essential for correct belt tension, timing accuracy & long-term engine health.
Fits:
Porsche 968 1992 - 1995
Diagram Ref No 9.
The tensioner damper plays a critical role in maintaining correct tension on the timing belt, helping to prevent belt slippage, tooth skipping, or premature wear. By damping vibration and maintaining even belt pressure, it ensures smooth engine operation and protects against costly engine damage.
Timing belt tensioner dampers wear over time due to heat and mechanical stress. A failing unit can lead to incorrect belt tension, increasing the risk of timing belt failure and severe engine damage. Replacing the tensioner during timing belt service intervals ensures continued reliability and peace of mind.
Recommended whenever the timing belt is changed – helps maintain correct tension and protects your 968’s engine.

About Belts / Tensioners / Rollers
Engine Rebuild Belts, Tensioners & Rollers – Precision Timing for Reliable Porsche Performance
Engine rebuild belts, tensioners, and rollers are essential components in maintaining your Porsche’s precise engine timing and smooth operation. These parts work together to synchronise the camshaft and crankshaft, ensuring valves open and close at exactly the right time for optimal combustion. Over time, these components can wear or deteriorate, especially under high performance or extended use, making replacement vital during an engine rebuild or major service.
At Design911, we supply a full range of genuine and high-quality belts, tensioners, and rollers for various Porsche models including, 911, Boxster, Cayman, Cayenne, Macan, and Panamera models. Each component is designed for strength, accuracy, and long-lasting reliability — ensuring your rebuilt Porsche engine performs flawlessly mile after mile.
What Do Engine Belts, Tensioners & Rollers Do?
These components form the heart of the engine’s timing and
auxiliary systems. They:
- Drive
key engine components, including the camshaft, alternator, and water
pump.
- Maintain
accurate timing for optimal combustion and efficiency.
- Reduce
friction and noise through smooth roller and tensioner operation.
- Ensure consistent belt tension to prevent slippage or premature wear.
Together, they guarantee your Porsche’s engine runs smoothly, efficiently, and reliably — whether cruising or driving at peak performance.
Why Do Belts, Tensioners & Rollers Fail?
Exposure to high temperatures, vibration, and constant
motion causes natural wear over time. Common causes of failure include:
- Aging
rubber belts becoming brittle or cracked.
- Worn
bearings in rollers or tensioners leading to noise or vibration.
- Loss
of tension causing belt slippage or timing misalignment.
- Contamination
from oil or coolant degrading materials.
- Extended maintenance intervals leading to unexpected failure.
Symptoms of failing components include squealing noises, poor engine performance, rough idle, or even timing belt failure, which can cause severe engine damage if ignored.
Why Replace Belts, Tensioners & Rollers During an Engine Rebuild?
Replacing these components during an engine rebuild ensures long-term reliability and eliminates the risk of future timing-related failures. A fresh set of belts, rollers, and tensioners restores precision, efficiency, and performance — protecting your investment.
Benefits of replacement include:
- Restored precise timing and smooth operation.
- Reduced risk of catastrophic engine failure.
- Enhanced reliability and longevity of the rebuild.
- Quieter, more efficient engine performance.
All components available from Design911 are made using premium-grade materials, precision bearings, and advanced heat-resistant compounds, ensuring maximum durability and performance in high-stress Porsche engines.
