This is the O.S. Max 30VG(P) Rear Exhaust Monster Truck Engine with a Pilot Type Crankshaft included.

Features:
  • Same mounting dimensions as .21 size engines making upgrading easier
  • Machined aluminum piston, 3-port cylinder liner and double bushed knife edge connecting rod
  • SG (pilot) type oversized crankshaft with rubber-sealed front bearing and oversized rear bearing to handle high torque loads
  • 21E single needle Slide Valve Carburetor (OSMG2449) with insulated sleeve to prevent fuel vaporization
  • Advanced Bi-Metallic Liner (ABL) cylinder liner construction This process uses a double layer of plating material rather than one thick layer. This helps the metal bond to the cylinder and is more durable. Also, the plating process is more consistent, resulting in a more precise fit between piston and sleeve for better compression and longer life
  • Two year limited warranty (through the manufacturer)
