Description

We recommend this pump as an upgrade for the OEM LS3 oil pump in applications with added oiling system demands such as large external oil coolers, larger bearing clearances, turbochargers, etc. This is also the recommended oil pump for extreme (8000+) rpm applications. We recommend this pump as a replacement for the OEM L99 oil pump in all VVT applications.

  • Orange spring (installed) – 70psi bypass
  • Optional Yellow spring – 60 psi bypass
  • Optional Green spring – 80psi bypass

    7. I am going to be completing a DOD/VVT complete delete on a 2011 Chevy Silverado 5.3 LMG/LS Engine. I've heard I should change my oem high volume pump to a standard volume pump. Is this a standard volume and good replacement for my needs?

    Asked by Matt B. on November 27, 2020 4:16 pm
    A This pump will fit and work well in your application. When we do an afm delete/cam upgrade in the LMG we never change the oil pump unless there is a loss of oil pressure or damage from debris going through it. The higher volume pump is approximately 13% different. If the truck has several miles on it the additional volume is usually a good thing.

    A Steven on a mild N/A build the 10295 should work out fine. It is basically a stock LS3 type replacement.
