The Serpent ERYX 4.0 is the next big development stage for the 411 platform. Featuring an ultra-low center of gravity, optimized weight distribution, high performance geometry and top quality materials throughout, the ERYX is your car for personal best times !
Michael Salven the Serpent chief on road designer has worked intensively over summer with Marc Fischer and Viktor Wilck to develop the 4.0 new parts. Most of the testing was done by Marc and Viktor and the parts have been used in recent races already.
The Eryx 4.0 will ship end December worldwide.
Key new items in the ERYX 4.0:
- new 2.25mm carbon chassis; fully symmetrical for even flex
- completely new shocks absorbers; housing, lower cap, x-rings, machined bushings, shock rods, shock caps, membranes
- 2mm higher front carbon shock towers to mount the new shocks
- 2mm higher rear carbon shock towers to mount the new shocks
- Completely new mid-shaft pulley system with play free assembly, one screw fixture

- New Online PDF manual and ERYX 4.0 set-up sheet
rear lower suspension pin mounts in 0.5 and 1.5, prepared to be used with the innovative Reactive Rear Steering System
carbon fiber chassis in 2mm hard and 2.25mm semi hard versions
Key main specs:
- Serpent spring steel front Double Joint Cardan shafts
- hard compound molded suspension parts
- ball raced anti-roll bars
- centrally mounted servo-mount, lowest cg
- low friction belts and super true low friction plies
The Serpent ERYX utilizes a centrally mounted ball raced dual pivot steering assembly-rack in aluminum. Offset steering linkage for correct steering geometry and ackermann. The steering assembly allows for very precise steering and great control. The ackermann is adjustable by using shims. The system pivots on wider low steering-shafts, creating a more direct steering feel. The bearing in the levers are pressed inside for a play-free assembly
The unique and innovative servo holder has zero influence on tweak, as its floating above the chassis and mounted directly to the steering-assembly in the center of the car. This also keeps the weight lower than any other design.
For adjusting the cars toe-in and track-width, the ERYX is equipped with separately mounted suspension brackets on both the front and rear of the car. Each bracket features an easily recognizable number that corresponds to the setting being used and due to the way they are mounted allows the user to easily and accurately adjust their cars settings. The brackets are designed such way that they can be used in any position in the car. The inner brackets FR and RR are now split type, to allow for more flex. The split suspension blocks are mirror type, so you can use them either left or right and obtain a different desired setting. This way less different blocks are needed for a good variety of settings. Standard ones: : 3.5/ 0.5 split blocks in the rear, 2.0/ 0.5 in the front
DJC / CVD’s spring-steel
This car is supplied with a complete set of 4 high quality hard coated spring-steel CVD shafts, which are a highly consistent, efficient and durable way to transfer all the power the surface. The front ones are v2 type double joint cardans DJC, the rear regular CVD style shafts.
The newly designed very narrow chassis plate has been machined from 2.25mm carbon fiber. All holes in the base of the chassis have been countersunk .
The chassis further features extra holes to mount weights and additional stiffeners . All holes are as close to the centerline of the chassis, to create even flex.
Battery-stays carbon / alum
The battery pack is kept in place by 2 mounts on the centerline of the car, and 2 special carbon/alum mounts with slits to mount the glass-tape. The carbon brace can be easily adjusted to move the battery more forward or backwards. Below these the carbon Lipo battery holders are mounted.
The ERYX features a 2-belt configuration with a long front and a short rear Kevlar reinforced low friction belt that combined with precision molded gears makes for a super smooth and free drive train.
The Serpent ERYX features lowered shock towers 2.5mm thick carbon fiber shock towers on the front and rear of the car. Each tower sports many holes for adjustment of the shock absorber angle while the rear tower also acts as the mount for the rear body posts and the front tower accommodates a 3rd front body post.
The car comes supplied with a front spool which has been made from hard anodized aluminum and are used with blades to increase lifespan. The shape has been optimized to ensure that the part is as light as possible without compromising strength.
The ERYX is supplied with coded anti-roll bars front and rear with a composite centering bracket. The anti-roll bars are available in a number of thicknesses and are connected to the wishbones using short adjustable track rods, connected with a pivot ball to the lower front wishbone, and with a ball directly to the rear lower wishbone.
The anti-roll bars run in small tapered nylon inserts , and the anti-roll bar is centered through one captured center bushing.
Harder C-hub front
A standard system on most high-end touring cars, the ERYX features a front C-hub system in Hard composite. The car comes standard with a 4-degree caster block but is also supplied with a pair of 2 and 6-degree blocks. The C-hub is large enough to take out the drive-shaft assembly without dis-assembling the c-hubs.
Similar to the rear suspension in configuration, the front suspension sports a lower composite wishbone while the upper camber adjustment is handled using an aluminum track rod which is solid, lightweight and can easily handle impacts.
Rear section with harder arms
The rear end of the ERYX features stronger Hard lower wishbones . The lower wishbones can be used on both the left and right sides, minimizing the number of spare parts needed to bring to the track. The rear Hard upright features a pivot pin mounting point on the bottom and 2 upper camber link mounting holes for fine-tuning camber rise.
The front and rear end of the Serpent ERYX are fully identical and been designed for high performance and ease of maintenance. The rear bearing blocks have been designed in 2 pieces which allows the topside to be simply removed with 4 screws, giving you easy access to the differential for maintenance or adjustment. All the parts have been machined from aluminum and are anodized in gun metal grey.
The new one piece machined aluminum motor bracket is superlight and super low and suits both stock and mod gearing well. The small front alum bracket, can be fitted with an alum bushing with long screw to connect to the top-deck. It can also be removed to create extra flex. The separate machined brackets hold the light aluminum middle shaft/ 19T pulley.
Composite Gear differential with new material composite gears and X-axle
The ERYX comes supplied with a lightweight and smooth rear gear-differential. This super small differential can handle all the power of BL motors. Gear-diff can also be used on the front. The new version has new type composite internal gears and 3.5mm x-shape shaft and features coated aluminum outdrives. The metal gears can also still be used or mixed with composite. ( The ball-diff is optional).
Big bore shocks
The new Serpent big bore on road shock absorbers lower the center of gravity even further. They come with threaded coated shock-bodies, pre-load shock nuts with o-ring, harder membranes , super smooth and strong shock-rods with clip to hold the piston, perfectly machined pistons ( 1,2,3 and 4 holes in kit) in a new yellow material , top-level x-ring /bushing package, light spring-cups, strong ball joints. The advantage is that you can continue using the normal size springs as before.
High quality race-springs included with color coding, grinded flat for even load.
The front bumper has been made from a high impact absorbing foam material and is shaped to protect the entire front end of the car in the event of a crash. The bumper is held in place with a large top-plate.
The ERYX is supplied with high-quality lightweight bearings with orange seals throughout, making the drive train very efficient and allowing it to run very smoothly.
- Ackermann: two positions on the steering blocks , and the steering plate with shims
- Camber: adjustable front and rear
- Toe-in: adjustable front and rear
