The Shocks can be used with either a Bladder or Emulsion setup and the kit includes a set of molded pistons to choose from. Shock Collars with inner o-rings are used on the threaded bodies to set-ride height and an optional set of 5 springs-sets is available to fine-tune the suspension settings.
  • Front Upper Bulkhead: The front upper bulkhead supports the upper links and shock tower. The front section allows the option to mount a front wing and sway bar unit
  • Front Wishbones: The front Wishbones are made from a super strong composite material. The arms are angled to optimize the CG and pivot on 3mm captured pins on the innner and outter arm. The arms have 2 mounting positions for shock angle and can use an optional anti-roll bar if needed.
  • Front & Rear Track Rods: Spring steel front and rear track rods are mounted to durable composite captured ball joints. The track Rods have L/R threading for easy adjustments.

  • Battery Space Mount & Weight Balance: The battery is mounted perfectly in the center line of the car, and can be moved forward or back to adjust the weight balance. Pieces of hard foam are included to secure the battery in position. The battery-top-brace has a secure quick release system with handy twist nuts.
  • Differential: The limited slip ball differential is a super compact, effective and durable unit. Utilizing 1/8 inch diff balls for ultimate durability. The structure and assembly similar to others in this class, but the high quality parts and function will make it stand out. The height of the diff can be changed.

The kit goes together amazingly well. Best kit I have ever built and I have been building and racing RC in excess of 20 years. The shocks are as smooth as silk. On track it is incredible even at kit standard settings. This 2wd platform is going to do something special over the next year to come and this is just the beginning. Can't wait for the mid motor version as well!

Kit was a bit frustrating to build. The shock pistons were not symmetrical and I needed to trim them down to fit the shock body. The the adjustable heights for the diff are not labeled for the lower out drives so can be a challenge to get aligned. The kit is a bit perplexing, high quality carbon fiber shock towers and battery strap and then cheap plastic nuts for attaching the tops of the shocks to the shock towers. Also, the wing attaches with screws which is very secure but a pain to take on and off. The biggest flaw are the captured ball studs. So challenging to screw in and chances are your 5mm nut driver won't work on it. All that being said, just running the stock setup this thing handles fantastic. It was as dialed (if not more so) than my Losi 22 that I'd been tinkering with for a year. I'm crazy impressed with how much steering it has. I can run my shorty pack all the way back for maximum traction with no loss of handling. I can only imagine how good this buggy will be as I dial it in more. It's a bear on the workbench and a beast on the track.
