Honda K20/K24 Oil Chain Tensioner 13450-RAA-A02

Honda K20/K24 Oil Chain Tensioner - OEM Part 13450-RAA-A02

If your K-series is rattling on cold starts or you're rebuilding after a chain failure, this is the part you need. The Honda OEM Oil Chain Tensioner (13450-RAA-A02) is the factory hydraulic tensioner that keeps the oil pump drive chain loaded correctly on K20 and K24 engines. No aftermarket guesswork - this is the exact component Honda engineers spec'd for these blocks from the factory.

The oil pump chain on a K20 or K24 is a low-attention item until it fails. When the tensioner loses its preload - whether from age, oil starvation, or extended drain intervals - you get chain slap that can damage the oil pump sprocket and, in worst cases, cause oil pressure loss at high rpm. Replacing it with the OEM unit (13450-RAA-A02) restores factory preload spec without any shimming, adjusting, or calibration. Install takes 60-90 minutes and reuses your existing bolts and seal - no additional hardware needed.

Features

• Genuine Honda OEM (13450-RAA-A02) - Cast and machined to Honda's production tolerances. Not a reboxed aftermarket unit.
• Hydraulic preload design - Maintains correct chain tension across the full operating temperature range, including cold start and sustained high-rpm use above 8,000 rpm.
• Eliminates cold-start chain rattle - Worn tensioners are the most common cause of that characteristic K-series rattle on first start. This fixes it at the source.
• Hardened plunger and internal seals - Built to handle heat soak and extended oil change intervals. Holds up in boosted applications running higher oil temps.
• No additional hardware needed - Reuses OEM bolts and seal. Direct swap with zero cutting, tapping, or tuning required.

We stock this part at Hybrid Racing because K-series builds - whether it's a Type-S refresh, a Civic Si timing job, or a full swap - don't leave room for off-spec components in the oiling system. When you order the OEM tensioner, you're getting the part Honda put on the engine the first time.
