This is the X Factory X-6 Cubed B4 Conversion Kit. This kit allows you to convert any version of the Team Associated B4 kit into an X - 6 Cubed 2wd buggy. The X Factory X – 6 Cubed retains many of the same unique X Factory features that made the X - 6² successful, but has combined these features with a narrow carbon fiber chassis design and high quality machined aluminum parts. The chassis design is similar in some ways to the X – 60CF and SCX – 60CF, with the addition of buggy-specific features that make the X - 6³ a true masterpiece. The narrow carbon fiber chassis has been combined with an adjustable battery layout and an adjustable flex top deck concept that helps make the X - 6³ faster and more nimble than the previous model and better suited to a wider range of track conditions.

The XFCK030 includes all the parts needed to convert your B4 buggy into an X - 6³, including ASC7667 & ASC7668 outdrives and XFC6203 bearings that are required to fit the B4.2 diff into the XFC50041 transmission case. 


X– 6³ Features:
  • Carbon Fiber Construction: Carbon fiber chassis plate, top deck plates and chassis brace
  • Adjustable Chassis Flex Top Deck: Adjust both the amount of flex and where the chassis flexes.
  • Slim Design: Delivers improved cornering and performance over bumps.
  • Lightweight: Very close to minimum legal weight out of the box. Lighter than most buggies.
  • Rear Shock Tower: Rear shock tower has been moved forward. This moves the wing forward for better performance in the air.
  • High Quality: High quality carbon fiber and polished aluminum components.
  • Body & Wing: Redesigned body and medium downforce wing. Original high-downforce wing still fits.
  • 4-Gear Transmission: Uses the standard X Factory 4-Gear transmission.
  • Rear Pivot Block & Control Arms: Uses X – 6² rear pivot block and control arms.
  • Battery Options: Uses either saddle or shorty pack; both can be moved forward or back to adjust weight distribution.

NOTE: The car shown in the photos is a prototype. There are minor changes between this and the final production product. The biggest change is the way the ball studs are mounted to the rear tower. The ball studs will be in the same location in the production version, but will be mounted vertically. Also, the body mounts are not shown on the car, but are included.

Needed to Complete:

  • B4, B4.1 or B4.2 Kit
  • Tires, B4 Compatible Wheels & Tire Glue
  • 2-Channel Radio System & Steering Servo
  • AA Batteries for Radio System
  • ESC & Motor
  • Batteries & Charger
  • Tools
  • Paint for Polycarbonate Body

X Factory X-6 Cubed B4 Conversion Kit (B4/4.1/4.2)
The car is great. I know there is a huge back-order on them, but it is totally worth the wait. Very smooth and has a ton of different was of tuning the car. Went together very well, couldn't be happier with it!

X Factory X-6 Cubed B4 Conversion Kit (B4/4.1/4.2)
This kit is absolute junk and I really hate to say it because I was hoping for the best.,allignment is horrible and I stripped half my screws trying to suck the parts together. You have to tap the holes and finish the carbon parts with sand paper and glue. For the price I really expected a kit ready to assemble. At this point I have so many stripped screws stuck in it that ill never get it apart to return it and I ruined my factory b4 to do so. Guys for this price and quality just go get the latest and greatest factory kit and call it good .

X Factory X-6 Cubed B4 Conversion Kit (B4/4.1/4.2)
Just put this kit together and I found it to be not the easiest to assemble. A lot of the carbon fiber parts did not fit perfect so I had to grind down some areas to make them fit. Also the kit did not provide enough screws but no big deal I had plenty of extras lying around. The worst part is the steering assembly hits the left support brackets so you don't get full left steering unless you grind down the brackets pretty thin and still hits a bit. Also the body and wing are terrible looking, about as basic as it gets. On a good note the car looks awesome with the carbon fiber and is really light weight. I haven't driven it yet so we'll see how it compares to my B5m.

X Factory X-6 Cubed B4 Conversion Kit (B4/4.1/4.2)
To start, I've never drove an X-Factory vehicle but I race with one of their sponsored drivers. This conversion kit really is an excellent kit for anyone racing. It's surprisingly durable so don't worry about breaking the parts. HOWEVER, my problem with their kits is you first need to purchase a B4 Team Kit THEN you have to buy the conversion kit. In the end, your spending almost as much on a 1/10 scale 2wd buggy kit as what it would cost for a 1/8 buggy. MIP has a "Pro8 Pro4-Mance E-Buggy Conversion Kit" to convert a SCT to a 1/8 buggy for $100 so there is no reason this kit should cost as much as it does... In the end, if you have the money and are dedicated to both AE and the 2wd buggy class, then this kit is a good buy. Otherwise, save some cash and stick to the stock B4.2 or TLR 22 2.0.
