Red Truck Diesel 4wt 10ft Fly Rod, 4-piece, 4100-4

(2 customer reviews)




An incredible nymph rod with a little more backbone.

This rod is very much like the Diesel 3100-4 fly rod, but we’ve added a little extra “umpf” to the new 4wt 10ft 4-piece. Here is the perfect rod to give you extra length for line control and beefed up tip to react to any grab from a striking fish.  This rod has gone through some serious testing with various guides on small, medium and big water. They all agree that the new Diesel 4100-4 is perfect for bigger fish, heavier rids and as an all-around trout catching machine.

We’d like to give special “THANKS” to Jonathan Neyman and the team at The Fly Box in Bristol, Tennessee for helping us field test and put this rod to use!


  • A great rod starts with the grip. Red Trucks switch grip is not only ergonomic but enhances feel and efficiency of casting and fishing.
  • Versatile and able to fish with “high sticking” or indicators.
  • Sanded and precision fit ferrules, where the rod pieces come together, allow for repairs in just a few days and eliminates the need for you to ship the entire rod back to us.
  • Effortlessly cast a variety of setups and rigs.
  • The extra length makes roll casting and mending much easier.
  • Powerful mid-section and butt for ease of flies.
  • Hand made with incredible craftsmanship and premium components.
  • Up-locking reel seat
  • All of our Diesel rods are proudly made in South Korea.

  1. Forrest

    The 10’4wt has become staple in my line up for my customers. Has power to throw larger nymph rigs yet still tons of delicacy to throw long leaders and small dry flys. 100% recommend for someone looking for a “do it all” rod.

    The 10ft 4WT Diesel is my daily driver guide rod. Beginners love to fish it but it keeps pace with experienced anglers just as well. It’s crazy versatile, and a no-brainer to add to your quiver.
