JD Performance Steering Stems are not only expertly designed, but they are built to last. Using a heavier gage tubing allows for added strength, while precision design provides superior fit.

Not all riders are the same size, but all Quads are, so adjust the ergonomics of your bike with a PLUS length stem. Improve comfort with Anti-vibe mounts.


Stems are all anti vibe 
$309.00 w/ 7/8" or 1 1/8" clamp 
$259.00 w/o clamp (anti vibe hardware included)

In order to provide extra strength and still use stock bushing, JD Performance starts with a larger diameter tube and reduces it where the bushing is positioned. This will allow for stronger bend resistance and allowing for all the stock bushing and clamps to fit perfectly. No other company has this much attention to detail.

Does your stem look similar to the one pictures on the left?  It's time to upgrade and enjoy a significant leap in performance!

Want a set of arms built to your specs? We've got you covered. Since all of our arms are handbuilt to order these days, we thought it only fitting to also offer them CUSTOM for your specific application. Weather it be in wall thickness, varying from .065 for lightweight TT racing  to .120 wall chromoly for the XC racer, as well as our standard thickness (most common) .095 wall.    Need a specific shock mount location to go with a special shock configuration?  Give us the specs where you want your shock mount, and we will  build it for you. (a small fixturing fee may apply). So now you can choose from +1,+2,+3,  also +1 forward, long shock, std shock, regular straight style,max ground clearance (MGC) arched . And choose your color. We offer a variety of colors, but if you have a special color, give us the paint code ,and we will see what we can do. (some colors may cost more). So just give us a call, and we can figure it out together.  

Are you to tall for your quad? Adding +1 or +2 inches to your stem could provide extra comfort for those who feel a bit cramped. Moving the clamps +1/2 forward can even adjust the balance of the quad by changing the position of your body. Call JD Performance and ask exactly how it could affect the way you ride. In order to make a stem stronger, you need to start with a larger stronger tube.



Many companies are building stems, but very few understand what stresses your bike endures while riding or racing. JD Performance uses their years of experience to make sure that every stem has solid construction that will provide years of flawless use.
