I don't like the cheap quality plastic bushings, ( brittle) and the crap metal pins with bad chroming. I started looking for bearings but the tubing isn't perfectly sized after welding. would need machined. Ive broken 3 bushing at Mountainridge, and 1 at Hatfeild Mcoy, The arm moves forward and back too much, caught a tree and few rocks, and it slams the upper arm into the bushing lip, and shears it off. Im not sure if anyone else sells bushing for them, they are a different size than stockers, Alba sells a rebuild pack with same low quality pins for about 30 bux ish. Like I said, I love the arms, bushings and pins .. not so much. I just pulled my fuel valve out a few weeks ago, and it looked just like that with a few bugs and legs.
