TRF421X A Parts, suspension arm spare part

TRF421X A Parts Upper Suspension Arm (2) is a dedicated spare part set for the TRF421X platform. The pack contains 2 upper suspension arms, giving a direct way to replace worn or damaged suspension pieces and return the chassis to its intended running condition. Within an RC chassis, the upper suspension arm is part of the linkage that guides wheel movement as the suspension works through bumps, load changes and cornering forces. Replacing this section can help bring back the original fit of the suspension area when a heavily used car starts to show play or after contact has stressed the arm. The A Parts designation also makes this set easier to identify when sorting workshop stock or matching replacement components to an existing build. This spare part suits routine maintenance, race-day repairs and keeping key chassis components ready between running sessions. For builders who maintain a TRF421X regularly, a matched 2-piece set supports quick parts changes and a more orderly spares setup at the bench or track.
