Gates T304RB Engine Timing Belt

Gates T304RB High Performance Timing Belt

The Gates T304RB is a high performance automotive timing belt built for Subaru and Saab applications that demand precise valve timing and durable construction. It uses an HSN belt material with fiberglass cord reinforcement and a modified curvilinear tooth profile for consistent engagement in high-output engines.

Part of the Gates RPM Timing Belt line, this blue performance belt is engineered for engines that see higher heat and load than standard street applications. If you are servicing a Subaru Legacy, Impreza, Forester, Outback, or Saab 9-2X, the T304RB provides a direct timing belt option for the listed fitments.

Key Features

• Gates T304RB high performance automotive timing belt
• HSN belt material for heat resistance and durability
• Fiberglass cord reinforcement for strength and stability
• Modified curvilinear (III) tooth profile
• 223 teeth with 8 mm pitch and 70.236 in pitch length
• Blue belt construction for easy identification
• No timing marks

Product Details

The Gates RPM Timing Belt line is built for performance-focused engine service, with materials selected to handle elevated temperatures and the demands of higher horsepower engines. This T304RB timing belt uses HSN elastomeric composite construction and fiberglass reinforcement to maintain tooth integrity and dimensional control under load. It is a direct replacement timing belt for confirmed Subaru and Saab applications, including Subaru Legacy, Impreza, Forester, and Outback models, plus the Saab 9-2X.

This part cross-references Dayco 95304 and Bando TB304 for the same application. The Gates T304RB part number is also listed alongside Gates T304 in interchange data.

What It Helps Address

• Worn or stretched timing belt service intervals
• Noise or irregular operation from an aging belt
• Loss of valve timing accuracy in interference engines
• Heat-related belt deterioration in performance use
• Service replacement for Subaru and Saab timing belt maintenance

Installation Notes

Verify engine code and model year before installation, especially on Subaru Outback applications with VIN 4th digit G. Confirm the belt profile, tooth count, pitch, and pitch length against the original part before assembly. Because this is an interference engine application on the listed vehicles, correct timing alignment is critical during service. The belt has no timing marks, so follow the factory timing procedure and inspect related components during replacement.

Quality Assurance

Gates manufactures the T304RB as part of its high performance RPM timing belt line, using heat-resistant HSN materials and fiberglass reinforcement for demanding engine environments. Fitment is confirmed for 1999-2012 Subaru Legacy, 1999-2011 Subaru Impreza, 1999-2010 Subaru Forester, 2000-2009 Subaru Outback, and 2005-2006 Saab 9-2X applications.
