Serpent designer Billy Easton from USA, is part of a team of designers, each with their own specialty. Billy used the input from many Serpent drivers, team drivers and distributors, to create this EVO version 1/8 buggy. The focus is as always on performance, but we have paid a lot of attention to ease of use and durability.

For drivers that also run electric 1/8 buggy, Serpent offers the Cobra SRX8-E which is based on the same platform and shares many parts with the GP version, so it’s an ideal combination.


The chassis cnc machined from 3mm aerospace type 7075 T6 aluminum and comes anodized for durability. All holes in the chassis are countersunk.
The pocket for the flywheel is large enough to suit most commonly used starter wheels. The sideguards mount to the bend chassis-sides from the inside with pre-threaded holes in the chassis. The chassis offers good size surfaces for the down stops.


The composite sideguards help to keep debris out of the car, add rigidity to the chassis and support the body. The sideguards are fixed to the chassis from the top in pre-threaded holes in the chassis. This way the screws are protected well and it’s easier to re-assembly when needed. The sideguards feature a pocket on the outside to allow mounting some felcron tape to guide / fix the body.

Engine mount

Lightweight CNC machined engine mount in 7075 T6 aluminum with pre-threaded holes and large contact area with chassis, comes grey anodized .

Chassis stiffeners Extra-long chassis stiffeners, front and rear in composite material to offer the right flex and prevents the chassis to bend too much. Easy locking fastening system.

Steering system – servo saver

The dual axis steering system with integrated servo saver is mounted under an angle for less bumpsteer and a more direct steering feel. The axis are made in lightweight aluminum. The new bell crank accepts a bearing raced crossbar with zero slop. It designed with the optimal Ackermann to increase the cars drive-ability.

Servo saver

These servo saver parts not only have the right Ackermann, but also have a good internal servo saver design. It incorporates a helix in order to guarantee the proper operating of the servo saver assembly. The servo saver spring is protected by a dense foam cover, to keep debris out. The spring pre-tension clamp nut can be locked in place to avoid turning loose.

Fuel tank

The125cc fuel tank with the spring and cap allow the pressure to be more equal across the entire top of the cap, as well as the design of the cap has no flex . The clunk has been enlarged so it will sit at the bottom of the tank and will not pop up or float at the bottom. While the drain section on the top has been improved where there is now a 4mm hole that will allow dirt and debris to escape and not clog. The fuel-tube clips now mount to the tank with screws so you won’t have to worry about losing them. The tank pull will enable faster and more secure refueling. The tank is further away from the exhaust , which will prevent melting of the tank. The kit includes purpose made insert to reduce the content if needed. The tank mounts on 2 strong composite poles with rubber grommets for flexible mounting and allow easy dis-assembly for checks and cleaning.

Air filter

High quality 2 piece dense foam for perfect filtering ( use top-quality air filter oil only ). The holder allows for easy assembly. On the front -top side the mount is attached to the center support with a spring wire, fixed with a body clip. The new rubber elbow allows for good airflow and features wide grooves to apply tie-wraps.

Center diff mount

Durable center mounts with large size bearings to mount the brake system and center differential. A molded brake disk guider is mounted on the brackets. The whole system is made as low as possible for CG reasons. The sleek top-cover keeps dirt out and guides the 2 brake cams.


The SRX8 provides a conventional braking system with brake cams, steel disks and steel pads with effective pre-glued brake pads.


The effective 4-carbon shoe race clutch is continued . It can be completely pre-assembled and then be mounted to the engine. The system comes with a light and small aluminum flywheel and durable spring steel 14T clutch-housing.

Differential cases

The strong molded differential cases which contain the differential and supports the shock towers. The differential front and rear can be removed after taking out only 4 screws and removing the anti-roll bars, super-easy!


The compact gear diffs with large oil volume. The diff has cavities designed specifically for closed cell foam. This foam will compensate for expansion of the oil, which will allow us to fill the diffs more full, keeping the gears fully engulfed in oil. The cavity where the gears rest has also been redesigned so that there is not low pressure zones outside of the gears. This will keep more oil on the gears even when spinning at high rpms. This in turn will keep the diff more consistent at low and high speeds as well as hot or cold .

Differential gears 28 / 14 / 44

The hard metal 28T and 14T satellite gears have a larger overall diameter, to make sure they are more in oil, making the diff more consistent , smoother and stronger . The steel 44T ring gear is light and has a perfect match with the new 28T gear.

Wheel axles / hex / boots

The durable Serpent spring steel wheel axles are captured CVD style and have rubber boots to protect the system and bearings against dirt and dust, so it will all last longer. The wheel hex is a durable hard aluminum version which fits all popular wheels very well. The pins in use are 3mm ones to increase durability.

Steering blocks

The steering blocks are made in 7075 T6 aluminum and are anodized in black. These steering blocks have been designed to allow you to change the Ackermann at the steering spindle as well as give us the optimal scrub offset in conjunction with the caster block. The bushings press into the blocks and reduce any unwanted play.


The new 15 dgr c-hubs are made in 7075 T6 aluminum and are anodized in black. These open style very durable units allow enough space to allow for the maximum steering-angle and allow space to mount the rubber dust protectors on the CVD system. As optional we offer 13, 17 and 19 dgr alu c-hubs too.


The new strong composite uprights come into play on the Team edition. Offering 2 lower and 4 upper positions for set-up.


Very durable and long molded wishbones front and rear. The composite is chosen to have enough flex when needed. The design has pockets in the top and bottom part of each arm to mount the standard molded insert plates, or the optional carbon fiber ones. In that way you can choose the right arm flex for each condition. Even different or no inserts front or rear and mixing molded and carbon inserts is possible. The molded inserts will stiffen the arms only a little, but keeps them cleaner. The carbon ones, or mixed with molded ones will stiffen the arms a lot. Many options to try and apply.


The mudguards are offered in lightweight transparent polycarbonate and can be left clear, be painted or skinned as preferred.

Shock towers

The front and rear shock towers are durable 4.5mm 7075 T6 aluminum units, CNC machined and laser engraved with Serpent logo.

Anti-roll bars

The anti-roll bar system is the best around. Precision made wire runs in ball raced adaptors on the front and rear diff case-plates. Super free and stabile. The wire connects to a ballpoint which is fitted with a pivotal to the wishbone. The works!

Suspension brackets

The suspension brackets are CNC machined in 7075 T6 aluminum and grey anodized. They key into the chassis for perfect fit. The brackets have precision machined pockets to use inserts to alter the set-up.


Durable polished steel 3.5mm rods are used with hard anodized caps and threaded shock-bodies. The seal pack consist of machined bushings and new x-rings and is kept in place with a small inside clip. The shock pistons are machined delrin units for best performance. The shocks in the kit are membrane style, with emulsion type hard coated caps and seals to be offered as option.

Shock springs

Race shock springs which are pre-selected and paired. The shock springs are grinded flat for perfect operation.

Wing rear black

The new flat type rear wing is a very effective medium downforce unit with large side wings. The decal sheet offers side wing decals to apply.

Wing holder rear

The rear wing holder is a super durable and light one piece molded unit . The set includes wing-spacers to put the wing under a range of angles.


Avenger style high downforce body is developed for the SRX8. Cab-forward style body with small fin on the roof for stability. Nice flowing sides with small rear upward fins for rear downforce. Enough space to allow for air filter, engine head, carburetor and exhaust / exhaust adaptor. Top quality polycarbonate. The body has nice trim lines for easy cutting. Same for the body holes. A masking sheet is included to assist with paintjob preps.

Body mounts

This rear body mount has a rubber cushion in it. It allows the body mount to rotate front to rear in an impact or crash. This saves the body from breaking or tearing. The front one is a fixed type and is easy accessible.


New full color PDF manual in landscape orientation to have more space to explain all, and have correct layout for screen use as well. Full color version with additional detailed views and notes, and also showing the hardware in real size on each page. Serpent USB stick is included with all manuals and set-up sheets.
