Tired of snapping stock A-arms on your Losi Micro-B or Micro-T? Step up to RPM Heavy-Duty A-arms. They’re engineered for strength where it counts. Reinforced and built to last, they’re the upgrade your micro ride has been waiting for. Here are some of the updates we made:

  • The inner and outer hinge pin bosses are thicker than stock.
  • The overall width of the A-arm support beams have been increased by approximately 20%.
  • Front A-arms feature a triple beam construction for enhanced durability.

These strengthening upgrades are combined with some of the highest-quality engineering-grade nylons in the industry. The result is a set of ultra-lightweight replacement A-arms. They offer unmatched durability and performance. Place your trust in American-made products. Trust RPM.

Tech Notes: Replaces the front and rear A-arms from stock Losi #LOS-1768. Includes both front and both rear A-arms.
