THE GOLD STANDARD PROCESS
WHY REMANUFACTURED

NEW ISN'T THE ONLY WAY TO WIN.

A reman nFLOW engine costs a fraction of OEM new — without gambling on quality. Here's how every Gold Standard build comes together.

01

Teardown

Every engine fully disassembled and professionally cleaned on arrival.

02

Inspect

Each component measured and failure-analyzed against spec.

03

Rebuild

All wear items replaced with new premium components.

04

Test

Precision-assembled, bench-tested, and prepped for install.

VERIFIED OWNER REVIEWS

RIDERS & SHOPS RUN NFLOW

GOOGLE FACEBOOK NFLOW.COM
  • "I was in desperate need of an engine for my Polaris General before an out-of-state event. They said 7–10 days — I was leaving in 13. A new motor was on my doorstep, I installed it, it sounds great, and I made my trip. No other company could have done this for me."

  • "Had a great experience getting a rebuilt engine for my 2019 Polaris Ranger. nFLOW is the same company that rebuilds engines for one of the largest Polaris dealers in Minnesota — so you know you're getting the best in engine rebuilds."

  • "The engine arrived very well packaged and looked like new. The cost was just as cheap as I could have gotten the parts for, and after installation the Teryx runs amazing."

  • "I've had mine in now for several years with not one issue. They even put a High-Output kit in mine — Sportsman 800 and it RIPS!"

  • "The engine was shipped fast and installed great. It ran better than when the unit was new."
