This is an acceptable replacement for the OEM LS3 oil pump in stock and mild to moderate naturally aspirated applications with no additional oil system demands (larger cooler, increased bearing clearance, turbo, etc). This pump is not suitable for VVT applications.
- Red spring (installed) – 70psi bypass
- Optional Blue spring – 60 psi bypass
- Optional Silver “COPO” spring – 85psi bypass
Great products and prices
Great oil pump great fit and great oil pressure
Worked great for my l99 to ls3 conversion
Came super fast, box was a little banged up but not much
Stock replacement, operates as advertised. Great product.
