Spoke Nut Hot Rod Truss Rod

About This Item

Easy neck heel adjustment in electric guitars and basses. Smooth two-way action corrects upbow and backbow, giving complete control over the neck.

The 1/2"-diameter "spoke" nut is designed to protrude slightly from the heel of a bolt-on neck; you can insert a thin tool into the side of the nut to turn it, without pickguard removal.

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.

Hot Rod's 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; the 24" rod fits basses. 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.

Too long!

(Customer's Reviews)

This truss rod works fine, but I needed a shorter one, with a spoke nut, to fit a 32" bass neck.
No problem, I bought the cutting die and handle, cutted the rods to lenght, putted threads on the ends, screwed them to the nut, and that's done!
A little expensive for one neck, but it works.
It would be helpful to find a 22" truss rod in the catalogue


Much better appearance (spoke-end)

(Customer's Reviews)

The good folks at StewMac responded appropriately to the justified criticism of the condition of the visible metal spoke ends. The latest set of units I received (May 2016) appeared to be bead blasted; the matte finish spoke end was uniform in color and surface finish. These easily adjustable dual rod truss rod assemblies are back up to the high quality standards we expect from this world class supplier of guitar parts. Thanks!


Lower Quality , Makes noise , Needs more QC

(Customer's Reviews)

Four years ago these rods came they were fluid and had no tarnishing. Today the rods are the shame shape and size. But they make slight noises and need to be oiled, The nut itself comes with rust and tarnishing they are also no longer polished they come as if fresh cast and just thrown on with no QC almost seemingly like a different material from years past. Unfortunately I will no longer order these rods until we get email of some improvement on this end.


Specs are off. Only useful for 25-1/2" scale.

(Customer's Reviews)

The spoke wheel is an excellent design but the adjusting wheel is pretty dirty looking, especially at this price. I can deal with polishing it up but the catalog specs need amendment. This rod is actually 18-3/8" in length. They are too long for use in Gibson scale designs with 22 frets.


Spokewheel trussrods

(Customer's Reviews)

Overall StewMac products do the job. The quality continues to be quite a letdown these rods arrive oxydized and dirty. As an aside they require a very deep channel.I would like to think you can do much better


LOVE the nut, but not the rod, and not the quality.

(Customer's Reviews)

The spoke wheel is simply the best, most convenient truss rod adjuster available. I won't use anything else.

However, i'm not crazy about the Hot Rod. It's sloppy, and can rattle around a bit even when under tension. It's VERY deep and fairly heavy compared to other dual-action truss rods. And the inevitably seem to come tarnished, oxidized, and stiff, requiring some work to get them usable and presentable.

On the left is how they typically arrive. On the right is how they look after some brushing, grinding, polishing, buffing and waxing. StewMac, you can (and should) do better… especially for the price.

Three suggestions:

1) Make these with one threaded rod and one flat steel bar, so they can fit better in thinner necks. This would probably reduce the weight a little bit as well, and also take care of the rattling issue.

2) Please make them 1/4" wide so we can use commonly-available spiral cutters instead of having to purchase your proprietary 0.225" router bit.

3) Make the spoke wheels out of stainless steel, or at least plate them so they're more presentable to our customers.


Good but a bit disappointing

(Customer's Reviews)

Spoke nut was askew against the steel bar what required me to make baggy hole to set the rod properly. I do hope this will be improved right away.


Rusting on rod-

(Customer's Reviews)

For the most part it seems like a great solid rod, but straight out of the box, the rod had rusting on the adjustment nut and on the thread of one of the rods, right through the double nut. Also the nut isn't nice and shiny looking like on the picture. A bit disappointed with quality, but it should still do the job. 6/10


Quality Decreased

(Customer's Reviews)

For a long while i'm aware of SM truss rods. Till the last time i always got happy with them. Thats why i kept buying. But the last one i got, thats another story. I saw the material quality of the adjustment tip ,particularly, decreased. Okay, not that bad but i'm not fully satisfied with the spoke nut truss rod. I think i'm going to keep using standard truss rods of Stew Mac next time, not spokes...


great adjustment

(Customer's Reviews)

convenient adjustment system, high-quality material.
