Product Description
Genuine GM 19166181 LSX Engine Block Rear Cover O-Ring Seal
Fits GM Performance LSX Engine Blocks Only – Sold Individually
Complete the rear-cover assembly on a compatible GM Performance LSX engine block with Genuine GM rear cover O-ring seal 19166181. This application-specific seal installs between the rear cover and LSX engine block, providing the corresponding GM sealing component required at this connection during engine assembly.
Designed specifically for GM Performance LSX blocks, this rear-cover O-ring is suitable for new engine builds, rear-cover service and LSX engine rebuilds. Its Genuine GM Original Equipment identity and exact 19166181 part number make it easy to locate the correct LSX rear-cover seal instead of selecting a seal intended for a different LS block configuration. One O-ring seal is included.
Key Features & Benefits
- Genuine GM Part Number 19166181: Manufactured as a Genuine GM Original Equipment sealing component for the supported LSX engine-block application. The exact GM part number provides a clear reference when sourcing the correct rear-cover O-ring for an LSX assembly.
