I actually bit the bullet and just bought a "parts" kit...an extra kit incase anything breaks..
I've had great luck. The only thing that has truly broken is the rear shock tower, after a hard 60 minute main on a track with huge jumps (designed for 1/8th). If you buy a kit now, it'll include the aluminum hubs and upgraded axles.. I'd also recommend the aluminum hubs, and you'll be pretty bulletproof! It's a good reliable truck!
