Want a set of arms built to your specs? We've got you covered.
All of our arms are hand built to order so we thought it only fitting to step it up even farther and offer you CUSTOM builds for your specific application. Whether 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). Now you can choose from +1,+2,+3,  also +1 forward, long shock, std shock, regular straight style, max ground clearance (MGC) arched. Plus you can 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).

The bottom line is that we are only a phone call away and will dedicate the time to match your exact specifications with personalized service where we can figure it out together.

$70 upgrade when purchasing arms

  Tie Rod End Upgrade 
Upgrade your early model Yamaha/Suzuki tie rod ends.  The weakest link in these quads is the small 10mm male threaded ends.  All raptor 660,04/05 yfz, raptor 250, banshee, and blasters have the smaller ends. In 06 Yamaha stepped it up to a 12mm. We have complete kits (2  12mm tie rods and 4 new 12mm ends) to upgrade what you have now. And we also have the tie rod end upgrade you can get when you order your arms.


Note When you get the upgrade in your arm kit, you will get 12mm tie rods instead of the 10mm So if you are upgrading your old setup, or purchasing new arms, or just have worn out ends on your quad, we have you covered.


Upgraded tie rod ends in a/arm kit   $80

2  tie rods with 4 new ends   $129

Kits are available for Honda, Yamaha, Suzuki, Kawasaki

"The MGC are sick and they're hundreds of dollars cheaper than any company I could find. And the build quality is amazing." -- Customer Feedback

"I love these a arms, you can't beat them for the price. Thanks for a great product" -- Chris Porter #22
