arms
I noticed on mine as well the top arm was very loose. I put a thin hardened washer over the plastic bushing for the wave washer to back up to. Also wrapped the plastic bushing with 15 thou shim stock. All nice and tight now.
I am running alt impact chromoly a arms. They fit a tad loose on the top, but are strong as hell. I hit a gnar stump a few weeks back that sent me over the bars and flipped my sled. Zero damage, zero issues with my sled. Seriously impressed!!! The stockers would've folded just like they did last year when I bounced off a thick tree and ruined them. Note that I didn't hit the tree. I just bounced off it in a side hill. Stockers are weak!!!
