The updated Serpent SDX4 EVO 1/10 scale shaft driven 4wd buggy in a very clean, simple and open design. Designed to perform on all surfaces with versatile layouts in which motor, battery and speedo can be mounted in a variety of locations. Highly accessible for maintenance and set-up, with a minimal number of screws and screw types.
Strong composite lower suspension arms with mounting spots for the pivot ball activated anti-roll bar. The arms are a closed type design for aero effect, rigidity and clean looks. On the upper side optional carbon inserts can be applied in case harder arms are needed for handling. Composite insert plates are standard. The front arms have 2 shock leverage positions. The arms have been updated, to have more material around the center of the arm around the shock mounting positions to prevent breakage.
Strong composite lower suspension arms with mounting spots for the pivot ball activated anti-roll bar. The arms are a closed type design for aero effect, rigidity and clean looks. On the upper side, optional carbon inserts can be applied in case harder arms are needed for improved handling. Composite insert plates are standard.
The rear arms have 2 shock mounting positions on each side, front and rear. The front and rear shock mounting positions are different and the arms can be used on both sides of the car, so you have 4 shock leverage positions to choose form. In addition, the rear arms and shock tower allow the shocks to be mounted in front or behind the rear arms.
Furthermore, the arms have been updated on the shock mounting face to allow for longer screws to ensure that the shocks cannot pull out of the arm.
Hard coated aluminum suspension brackets for both the front and rear pivots
Small but effective composite front bumper to protect the front end. The angled front built in kick up allows for smoother landings.
The rear/rear suspension bracket can be used standard with o-degree or upside down as 3-degree anti-squat.
The front and rear bulkheads made from 7075-t6 are designed to optimize strength, while offering the shock tower additional strength. The transmission housings are neatly packaged in the bulkheads to further strength while allowing ease of assembly and disassembly.
Both the front and rear bulkheads allow mounting the ball-raced anti-roll bars. The wire type anti-roll bars are lasered for easy identification. The wires connect to the arms with the proven friction free super smooth pivot ball system. It is very easy to access and change the anti-roll bars as needed.
The motor is mounted securely to the CNC machined 7075 T6 aluminum motor slide. The slide has been slotted into position to ensure consistent and reliable gear mesh.
Center drive holders
The slipper clutch unit is held in place by the motor mount bracket and a H shaped lightened 7075 T6 aluminum holder topped by a carbon connector plate that also holds the cable guiders in place. The slipper can also be replaced by a gear differential in the center. Its super easy to access the slipper or central gear diff.
The lightened 7075 T6 aluminum uprights are same left and right and feature 3 camber link positions.
The front and rear wheel hex are 12mm industry standard size. The hexes are clamp type and anodized to last. Flanged wheel nuts are included to keep the wheels in place.
The strong composite body mounts are easily located in case used.
Top quality clear polycarbonate is used for the Spyder SRX4 buggy body. The nicely shaped body has flat sides and roof for extra downforce and great handling. It leaves enough space for electronics and cooling finds as needed. The body closely follows the chassis shape, so less debris can enter the car. The body comes with a white precut masking sheet.
Rear wing and wing holder
The strong clear polycarbonate wing is mounted to the nylon rear wing holder.
Durable Serpent designed wheels are included in white color for front and rear (tires and inserts are not included). Rear wheels are same as SRX2 and SRX4, the front ones have a different offset and are new. Compliant to the latest IFMAR rules.
Steering blocks and c-hubs
The lightweight composite steering blocks are combined with aluminum 7075 T6 c-hubs. The c-hubs has 2 positions for the camber link and can be further finetuned by using more or less shims. The c-hubs are 10 degree?s, other optional ones are 0, 3 and 5degree.
Steering Bell Cranks
The fully ball raced angled dual axis steering system with integrated servo saver function, offers an almost perfect Ackermann effect. Ackermann can be set with small plates which mount to the steering arms and the black coated aluminum steering brace has 2 holes to choose from. The servo saver has a pre-load nut to easily set the desired tension.
The steering system is mounted on a carbon fiber u-bracket which also connects the front left and right sides and acts stiffener.
NEW Front/Rear and center CVD?s
The EVO kit has been updated to utilize front/rear outboard CVD?s which have captured pins to ensure, you finish every race you start. The center drivetrain is no exception as it too was updated to have CVD?s, all captured. The outboard CVD?s increase efficiency and traction, while the drivetrain increase efficiency.
Updated 2.5mm Drivetrain Pins
To increase reliability, and prolong the life of the drivetrain, the Evo drivetrain has been updated to use 2.5mm driveshaft pins throughout.
Solid Hinge pins 3mm Hinge Pins
The EVO Kit has been updated to use solid 3mm hinge pins on the front and rear inner pivots. This increase reliability and also allows you to shim your arms forward or back. Being able to shorten or length the car will allow you to further fine tune your car for every track condition you will face.
Updated 2 Pad Slipper
The slipper assembly has been updated on the EVO to utilize 2 pads. By going to 2 pads, it will allow you a broader range of adjustment on dirt all the way up to Astroturf and Carpet. You can still use the old 3 pad slipper, simply by swapping out parts if you are looking even less slipper action on the most extreme conditions.
Manual / setup sheet / decals
The Spyder SDX4 comes with a PDF style full color manual on a Serpent USB stick which shows the assembly process in steps following the packed bags. The manual also encloses the exploded views and a ref-guide to make it easy to find the part numbers you may need of spares and optional parts. A latest version of the manual can always be found on our website as PDF too.
A default set-up sheet is included, but more set-ups can be found on our product page under set-ups.
A Spyder SDX4 decal sheet and a Serpent decal sheet are included.
The strong kit box includes the coded bags to assemble the car, as well as the body, rear wing and wheels, manual, set-up sheet and decals. Each kit is carefully packed and a checking decal can be found on the side of the box

In the rear the SDX4 features a carbon fiber chassis stiffener which is clamped between the rear/front suspension bracket and the bulkhead and extends to the center. The brace has 5 optional holes to choose the stiffness by placing the small stiffener pole and screw or even adding more poles/screws.
The system influences rear end flex and is set depending on grip levels and driving style.
Battery and stays
The SDX4 car accepts a shorty in standard trim, but you can also mount saddle packs as needed. The battery is kept in place by an easy to use composite battery-cover with a twist nut on one side.
The center of the car allows plenty of space to mount the most popular speedo and receivers, as well as the transponder. The car also allows enough space to enable nice routing of your cables. On the side of the slipper the SDx4 offers 2 special cable guiders.
