RCG Racing 18-Series Lengan Atas Suspensi Belakang (2pcs)

The bolts lined up perfectly with my stock mounting points, so the swap took under ten minutes. This upper arm feels way stiffer than the factory plastic piece, and my truck tracks straight again after a hard tumble.

I was worried about replacing the rear upper arm after a hard crash, but these two pieces bolted right on with no slop at all. The truck sits square again and the 18-Series chassis feels solid through turns.

The replacement upper arm fit perfectly on my 18-Series Short Course truck and the metal hinge pins feel much sturdier than the plastic ones that came with it. Installation was straightforward and my suspension is tight again after a hard crash.
