Description

 

Flyin Diesel Flexible Locking Dipstick – Cummins (1999–Current)

Clean up your engine bay and gain total flexibility with the Flyin Diesel Flexible Locking Engine Oil Dipstick, designed for Cummins engines where factory dipstick routing just doesn’t work—especially on custom builds and swaps.

This flexible dipstick allows you to mount the dipstick in virtually any location, including the factory position or a completely custom route. It’s an ideal solution for trucks running side-draft intakes, aftermarket intake horns, CCV filters, or tight engine bay layouts.

It’s also a perfect fit for Cummins conversions into Ford trucks, where the factory Dodge dipstick often interferes with accessories or simply won’t fit correctly.


🔧 Key Features

  • Flexible Mounting Design – Route and mount the dipstick wherever your setup requires

  • Locking Dipstick Handle – Prevents dipstick expulsion under crankcase pressure

  • Teflon®-Lined Braided Housing – Available in black or stainless steel for durability and clean looks

  • Easy-to-Read Flexible Inner Cable – Clear oil level readings even with custom routing

  • NHRA Approved – Accepted for use in all categories of competition


⚠️ IMPORTANT INSTALLATION NOTE

You MUST trim the inner dipstick cable to the correct length before installation.
Failure to do so can result in incorrect oil level readings, which may lead to engine damage.

Take your time during setup and verify oil level accuracy after trimming.


🛠️ Why Upgrade to a Flexible Dipstick?

  • Eliminates interference with aftermarket intake and CCV systems

  • Cleans up engine bay appearance

  • Solves dipstick fitment issues on engine swaps and custom builds

  • Provides secure, pressure-resistant oil level monitoring


🎨 Available Options

  • Black Braided Housing

  • Stainless Braided Housing


🚗 Fitment

  • 1999–Current Dodge Cummins Engines


🏁 Bottom Line

If you’re running a modified Cummins, building a swap, or just tired of fighting the factory dipstick, the Flyin Diesel Flexible Locking Dipstick gives you the freedom, safety, and clean look your engine bay deserves—without compromising accuracy or reliability.
