Mazworx SR20 Timing Chain Tensioner
$99.00
Upgrade your Nissan SR20 engine’s timing chain system with the Mazworx Timing Chain Tensioner. Designed to reduce chain wear and improve reliability, it works without oil pressure and fits both FWD and RWD applications. Available in multiple colors and compatible with S13, S14, and S15 chassis.
The Mazworx SR20 Timing Chain Tensioner is a high-quality upgrade designed to address the limitations of the factory hydraulic timing chain tensioner found in Nissan SR20 engines. This improved tensioner is engineered to enhance reliability and reduce premature wear, especially when upgrading to bigger cams or stiffer valve springs.
Unlike the original hydraulic tensioner that relies on oil pressure to function, the Mazworx tensioner operates mechanically without the need for oil pressure. This key design difference allows the tensioner to maintain consistent chain tension and reduce the risk of chain stretch, ensuring more stable valvetrain performance over time.
Key Features
- Improves upon factory tensioner design to handle upgraded valvetrain components
- Reduces excessive timing chain wear and premature chain stretching
- Does not require oil pressure, allowing reliable and consistent operation
- Helps improve overall engine reliability and longevity
- Variable fitment options for FWD and RWD SR20 engine setups
Fitment Details
The tensioner is available in two versions tailored to different chassis and engine configurations:
- FWD Version: Designed specifically for FWD setups where the oil filter is positioned close to the tensioner. This version includes a short bolt to ensure proper clearance around the oil filter.
- RWD Version: Recommended if your vehicle does not have the oil filter positioned near the tensioner. Suitable for rear-wheel drive SR20 applications.
Compatible with Nissan SR20 engines across S13, S14, and S15 chassis, this tensioner is available in Billet, Purple, and Black finishes to match your engine bay aesthetics.

Scared to be different? You can be safe knowing that you don't have to worry about the famous chain rattle. The product is simple to install an adjust. An if you get scared,they do have YouTube videos for those like me who rather see than read on how it's done. Plus it's purple!
