Traditional Fender adjustment nut for electric guitars. Smooth two-way action corrects upbow and backbow, giving complete control over the neck.

Easy to install. The Hot Rod® fits in a straight channel. For proper operation, this truss rod must be installed so that the active rod (the rod with the adjustment nut) is below the passive rod. A wooden filler stick is not required.

Smooth 2-way action with superior strength for stubborn necks. Stainless steel adjustment rod corrects upbow and backbow.

Our Hot Rod neck adjustment system features twin rods in threaded brass collars. The stainless steel active rod turns for smooth neck alignment, with 2-way action. The Hot Rod requires an access cavity for the adjustment nut, and a straight 7/32"-wide x 7/16"-deep slot (measured from the bottom of the fretboard) for installation.

The 18" rod fits many electric guitars. Overall length includes the nut.

We've designed the Router Bit for Hot Rod Truss Rods especially for routing your neck to fit our truss rods.

Excellent truss rod!

I have been using these for years in all my necks and have zero issues. They always work perfectly to correct any neck issues. Cellini Custom Guitars.

Easy installation - prone to rust

I'll start by saying that the truss rod is great but I have installed it on two necks and one of the truss rods picked up rust while the other is showing signs of starting as well. I would only wish that the metal in the knob be of higher quality. Other than that is pretty good.

Excellent item. I'm building my first solid body electric guitar so I'm always looking for items that make the process neat, clean and easy. This was it. Routered out the channel with an easy jig, drilled out a hole for the slotted nut and it fit in nicely. Installed, it worked perfectly. Thanks Stew Mac!

Easy Installation.  Works very well.

It was easily installed and has worked well on my Strat design. The price is not too bad either. I wish they come in shorter lengths (i.e., 14, 15 inches, etc.) so they can be installed in acoustic and archtop guitars as well as other stringed instruments. One thing to watch for, if your groove is 7/16" deep and you intend to apply some caulk in the groove under the truss rod (to minimize vibration), do not put to much caulk under the rod, otherwise, the truss rod top elevation may end up slightly higher than the groove, and in such case, you may have to file down the rod top ends some to get them leveled with the groove top. I do not use a filler strip and never had a problem with the vibration. I also wish the rod would require a bit shallower groove, i.e., 3/8" deep. It concerns me when the bottom of the groove is just about (or less than) 1/8" from the back of the neck and I do not want to end up with chunky necks. Also, I like to take the least amount of meat possible out of the neck for rod groove routing to maximize the energy transmission and minimize the effects of wood removal on the overall guitar tone. Please see the attached picture for a "safe" installation of the nut. This requires drilling a horizontal hole with the same length and diameter as the nut, install the rod carefully, then glue a small filler strip above the nut. This way, you are very unlikely to crack the groove (therefor, the neck) during the rod installation!

Perfect as always.

I use these truss rods in every guitar i build. They are well constructed, strong and smooth. It doesnt take more than a slight turn to make a big difference.

Hot Rods

When I'm feeling lazy and don't want to make a rod from scratch or the application seems to call for a double acting rod, I always choose a Hot Rod from Stew Mac. I've never had a problem with them and they are a snap to install.

Good truss rods.

By Jeremy Dumoit from Richmond, TX

These Hot Rod two-way truss rods work just fine. They're easy enough to install. The screw is a bit offset from center, and can be hard to get in the hole when installing the rod. I've cracked one neck this way. However, if you're careful, it's straightforward. They work great.

Not so good

By K Armand from Mahomet

Not what I expected. Please look carefully before you purchase. These are not like other truss rods.
