IMPORTANT BEFORE ORDERING
Are your Arms Stock or BDX?
Be sure to check your A-Arms to see if you have the stock Yerf Dog a-arms or the Buggy Depot or BDX a-arms. The BDX a-arms have small holes in the a-arm tabs of about 3/8". The stock a-arms have holes approximately 1.5". If you have the stock a-arms you will need the spacers thus be sure to check the stock a-arm option.
BALL JOINT "TORTURE TEST" DARE: Way back in 2006 when we first announced our claims of our joints' strength, members of the Buggy Depot Forum dared us to to actually lift one, so we did!
2006 Yerf Dog Spiderbox Lift
JUST ONE BDX JOINT EASILY HOLDS THE WEIGHT OF THE ENTIRE KART!
INSTALLS IN 10 MINUTES
Once your original joints are off, you'll only need TWO 9/16" WRENCHES to install our joints. They bolt right in. It's that easy!
FITS BDX, BMI, AND STOCK A-ARMS
Despite claims stating otherwise, our HD joints absolutely do work with A-Arms from BMI.
NO LOOSE AND WOBBLY "SNAP RING" JOINTS
Our kit bolts in! meaning you have the ability to fully tighten without hassles of wobbly snap rings.
Our design is a major advantage over snap-ring mounted joints. Snap rings don't allow you to fully tighten the joint into place, which is critical to the stability of the joint and suspension system overall. The snap ring design is a very loose fit which causes slop in the front-end and steering issues. The BDX joints clamp down at this location with nylock nuts, creating solid ridged attachment point torqued properly. This eliminates all movement of the joint in the A-Arm - which is impossible with the snap ring joints.
Also, the sheet metal mounting tabs that come on these karts stock is known to fatigue and break over time. Snap ring joints do nothing to help this. Our BDX joints clamp down on this weak area with a nut and high-shoulder extra-thick washers. This helps greatly but will not fully resolve the weak A-Arm tabs, which should be reinforced. We also offer reinforcement services.
HOW OUR "WELDLESS" JOINT MOUNTS WORK
Applies to stock and BMI A-Arms. BDX arms don't need the weldless mounts.
The oversized washer mounts (shown in the picture above) allow our joints to (tightly) fit the larger hole of all stock-spec A-Arms (like the BMI arms). They work like an adapter, requiring no welding or fabrication to work with stock arms. This a rock solid setup that has held up to the test of time on thousands of Yerf Dogs since 2006. (The weak stock A-Arm flange is a different story, look it up! It's a good idea to upgrade to HD arms anyway!)
This "weldless" no-hassle mounting setup for stock-spec arms was one of the best selling points of our HD kit back in '06. (Years before we later came out with our BDX HD A-Arms.)
INSTALLING ON STOCK OR BMI ARMS
INSTALLING ON BDX HD ARMS
Check out how beefy our A-Arm tabs are! Compare that to the tabs on your stock A-Arms.
If you're getting our BDX HD A-Arms, you won't need the washer mounts. Run the threaded shank directly through the hole on the HD Arm and you're good to go.
