The IAG Performance Red Racing Timing Belt is designed to work with all Subaru EJ series engines. The high-strength Kevlar construction and attractive red color make it a great choice for your Subaru engine bay. We have performed extensive testing of this belt on our Spintron testing machine, as well as our fleet of racing vehicles. In testing, we found that these belts ensure accurate timing and unmatched performance.

IAG Red Racing belts are lightweight and utilize EPDM Rubber for increased durability and performance in all climates. The Kevlar construction is 300% stronger than the OEM Subaru timing belt, and is also three times more heat resistant. The belt teeth are made of H-NBR grade rubber for additional strength.

The IAG Performance Adjustable Timing Idler kit is specifically intended to properly align the camshafts on Subaru EJ20/EJ25 cylinder heads and/or blocks that were resurfaced (“Reducing” long block length), or utilize thicker head gaskets (“Increasing” long block length). The ability to adjust and properly align the cams is recommended for any performance built Subaru.

The product is precision CNC machined and hand assembled in-house. Each idler features a machined 10mm hex enabling your socket to hold it in place while you adjust the timing to perfection. The idlers come engraved with the IAG logo on the face and are manufactured to strict OEM tolerances.
