A couple weeks ago my son and I were riding serious rocky trails and managed to break the left front a-arm. The spindles were fine but the bolts looked like they had been worked on using vice grips in the past so I replaced those also
Here's how it looked
Got in the new A-arms and all grade 8 bolts to replace the worn OEM stuff
Old part next to new one
The bad A-arm, you'll notice how bent it is as well as broken, the small piece at the top right of the pic is the bolt head, 5/8" bolt and it was frozen in place inside the A-arm so we had to cut it out in pieces using the angle grinder
The front of the kart had some pretty bad scratches so I sanded it down and painted it silver to match the new arms
Final results
Old
New
You'll notice how the tires sit slightly outward so that once there is rider's weight in the kart is sits level
Think the next mod for the kart is to change to oil filled coil-over shocks to try and take some of the bounce out of the ride
