The chassis plate has been machined from a plate of 2.5mm thick carbon fibre, which creates a perfect platform for the cars electronics as well as stiff structure, especially when combined with the equally rigid 2.5mm thick carbon fibre top deck. All holes in the base of the chassis have been countersunk while on the top of the plate, the area around the motor has been milled down to allow it to sit as low as possible. The plate features cooling holes below the motor and speed controller.

The S400 is supplied with colour coded anti-roll bars front and rear that are held in place using a 2 piece anti-roll bar mount. The anti-roll bars are available in a number of thicknesses and are connected to the wishbones using short adjustable track rods. Stiffness is quickly and easily adjustable by changing the linkage mounting points on the lower wishbones or alternatively by changing the position of the ball joint pivot point on the roll bar itself.

Serpent S411 - RCCX Shock absorbers

RCC Shock absorbers

The RCC shock absorbers are the smoothest and easiest to build shocks ever designed. Machined from aluminium and unique in that the shock bodies only open on the bottom half, they are really simple to assemble. The result is an ultra-smooth and air-free shock absorber thanks to the self-bleeding system incorporated into the design. The shocks are supplied with 4 different shock pistons.

Another great benefit is that these shock absorbers come pre-assembled in the kit, so you need only add shock oil.

Serpent S400 - Front end

Front axle

The car comes supplied with a front spool which has been made from hard anodised aluminium while its shape has been optimised to ensure that the part is as light as possible without compromising strength.
