This is the even upper a-arm for the Yerf Dog GX 150

MADE IN THE USA WITH 100% AMERICAN STEEL

Instead of discontinuing our USA-made product line, in 2017 and 2018 we doubled down and invested in new equipment and processes to make it easier to keep these items on the shelf long term. And lower prices! Read about it here.

BUY BDX - THE TOUGHEST GX150 PARTS AVAILABLE!

Heavy Duty Update! All of our HD A-Arms now come with heavy duty pivot tubes specially machined from over-sized steel tubing. Our tubes are twice as thick!.

FITS 3RD SPINDLE GENERATIONS

This arm fits the 3rd Generation setups where the A-Arms are all equal length.

FITS 1/2" GX150 BULKHEADS (AND EASILY DIY CONVERTED TO 5/8")

Most GX150's have 1/2" A-Arm bolts. Our arms match that common style, with genuine Oillite self-lubricating bearings/bushings.

If you have the less common 5/8" A-Arm bolts, you can easily use a 5/8" drill bit to ream out the pivot tube. A small amount of the ID will be removed. This A-Arm replaces BOTH styles. We don't pre-convert them to 5/8".

HD SUPER OILITE® SELF-LUBRICATING BUSHINGS

The BDX bushings are self-lubricating Super Oilite® Flange Bearings. Genuine straight from Oilite, no knockoffs. They're oil impregnated with synthetic "Extreme Pressure AM3-SPD®". Made in the USA.

The grey color of the bushing is due to the addition of sintered iron, making our bushings much tougher than the original bronze pieces.

PRECISION CNC CUT 3/8" THICK JOINT MOUNTS

Our tabs are 3x thicker than stock and will NOT rip, break, or bend. Precision CNC cut, and more precise than stock.

ACCEPT NO SUBSTITUTES!

Don't fall for guys telling you to save a buck and cut your own. You don't want to cheap out on parts that hold your wheels on. We've seen some hack jobs, that in the end get sent to us for proven reinforcements.

SUPERIOR ACCURACY!

When it comes to accurate dimensions, our arms win hands-down. Turns out that the stock A-Arms aren't very consistent or accurate. No wonder you're having wonky steering problems even since the machine was new.

DEAD-NUTS CENTERED BDX ALIGNMENT, EVERY TIME

VERSUS INCONSISTENT STOCK ARMS, YOU'RE LOOKING AT 1/4" OFF CENTER!

LIFETIME GUARANTEE

This part comes with a Lifetime Guarantee against breakages of the tab. After seeing many Yerfs with broken A-Arm tabs over the years, we designed this Heavy Duty version to combat the breakages. This unit comes with super thick mounting tabs for the ball joints, eliminating separation of the outer tab ring from the arm.

Note: BDX Heavy Duty Ball Joints must be used with this item. We don't sell original A-Arms due to their tab design.
