Full Pulley & Belt Kit – Tensioner, Idlers & Drive Belt – with Air Conditioning
This kit includes a replacement tensioner element, all three pulleys, a new drive belt, and is suitable for models with air-conditioning (option code 573).  

Maintain reliable auxiliary drive performance on your Porsche Mezger engine with this complete Full Pulley & Belt Kit for Porsche 997.2 GT3 and GT3 RS models equipped with air conditioning from 2010 to 2012.

Fits:

  • Porsche 997 MKII GT3 / GT3 RS 2010-11

Designed as a comprehensive preventative maintenance and service solution, this kit includes the essential tensioner, idler pulleys, and drive belt components required to restore smooth accessory drive operation, maintain correct belt tension, and reduce the risk of pulley or belt-related failures.

Kit Contents:
1x Original Porsche Tensioner Element 
1x Gates Drive Belt
1x OE Match Tensioner Pulley Incl. Nut, Bolt, & Dust Cap
1x OE Match Upper Idler Pulley, Cover & Bolt 
1x OE Match Lower Idler Pulley, Cover & Bolt

The auxiliary drive system on the high-revving Porsche GT3 Mezger engine operates under constant thermal load, sustained high RPM, and intense mechanical stress. Over time, tensioners, idler pulleys, and drive belts can wear, leading to pulley noise, belt slip, bearing failure, or reduced accessory efficiency.

Replacing all related components together helps ensure long-term reliability while protecting critical engine-driven systems and maintaining proper accessory drive performance.

This complete service kit is ideal for routine maintenance, engine refresh projects, preventative servicing, or resolving common issues such as belt squeal, noisy pulleys, or worn tensioner operation on Porsche 997.2 GT3 and GT3 RS models.

Engineered for precise fitment and dependable operation, this kit helps maintain smooth auxiliary drive performance for both road and track-focused Porsche applications.

Perfect for Porsche enthusiasts, independent specialists, and workshops maintaining Mezger-powered GT3 models.

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.
