RPM Adjustable Upper & Lower A-Arm (Blue)

With your purchase, receive at no cost:
This is a set of optional RPM Adjustable Upper & Lower A-Arms, and are intended for use with the Losi LST and Aftershock monster trucks. Camber is one of the most critical adjustments on a monster truck. The stock camber angles on the LST is set at zero degrees and the A-arms do NOT allow adjustability. RPM upper A-arms for the LST incorporate a tough 303 series stainless steel camber rod to create an adjustable camber RPM A-arm. RPM has included the anti-sway bar mount in the stock location as well. The lower A-arm is beefed up to take some serious abuse while maintaining stock shock mounts. RPM is the only answer for rugged, rigid, durable, and adjustable performance that works. These A-arms are  molded from RPM's bulletproof blend of nylons for the ultimate in rigidity, strength and durability.

This set includes one upper A-arm assembly (consisting of both upper A-arm sections and the connecting 303 stainless steel camber rod) and one lower A-arm. Two sets of these arms will be needed to convert the front end of one vehicle.


  • Super strong molded pieces
  • The first set of adjustable A-arms for the LST
  • Stainless steel camber rod for adjustment
