  • Carbon Fiber Front & Rear Shock Towers: The 4mm thick carbon fiber shock towers have multiple shock angle positions to fine tune the car for various track conditions.
  • 12mm Big Bore Shock Absorbers: The dual system 12mm big bore shocks feature hard coated threaded shock bodies and a unique cap design, combined with a superb o-ring and spacer package. 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.
  • Caster Blocks & Settings: Includes 0, 2.5 and 5 degree caster block inserts. The caster blocks are compact and strong, made from a special composite material.
  • Steering Blocks & Rear Uprights: The steering blocks fit 5x10x4mm bearings. The rear hub uprights use larger 5x14x4mm outer and 10x15x4mm inner bearings for performance and durability. The steering blocks and rear uprights utilize some of the best high strength materials available.
  • Rear Upright Settings: The rear uprights use included inserts to adjust the toe in from -2 to + 2 degrees.
  • Steering System & Ackermann: The steering system has a reverse swinging pivot system that optimizes the efficiency through all different types of corners. You have 3 Ackerman choices to choose from.
  • Wheel-axles & Wheel Hex: The spring steel wheel-axles use a 12mm hex adapter to follow current market standards. The front spring steel axle is fixed, while the rear wheel-hex is a clamping aluminum version.
  • Battery Space Mount & Weight Balance: The battery is mounted perfectly in the center line of the car. The design is optimized for saddle packs, but if a shorty type pack is used the battery 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.
  • Motor Plate & Motor Guard: The motor plate is a machined, anodized and lightened. The composite motor guard will keep your motor protected even after the hardest landings.
  • Anti-Roll Bars: Anti-roll bars can be fitted on the front and rear of the car, but are optional and are not included. They are recommended for high grip surfaces to tune the performance.
  • Rear Transmission Case: The composite rear transmission case is light and durable. It allows the customer to adjust the differential height for specific conditions. It also securely holds the motor plate and differential, and also supports the rear wing mount and carbon fiber rear shock tower.
  • Rear Driveshaft System & Wheel Axles: The spring steel drive shafts are thin and light, yet durable. The spring steel wheel-axles are 5mm, light and durable, supported by 10x14x4mm inner and 5x13x4mm outer bearings. These bearings are for sure to stand up the rigors of any track condition. The driveshaft pin is fully captured to prevent any failure.
  • Rear Suspension Brackets & Toe In: The 3mm spring steel pivot pins are held in place by the aluminum suspension bracket. Inserts are used inside the bracket to set toe-in and roll center. You can adjust the toe-in from 2 to 4 degrees and adjust the anti squat from 0 to 4 degrees.
  • Rear Suspension Arms: The mid motor specific long and durable angled rear suspension arms are very tough, and designed to withstand the rigors of the track and the hard landings. The rear arm offers 2 options for shock position and two mounting locations for the optional rear anti-roll bar if used.
  • Rear Chassis Skid Plate: The composite rear skid plate connects to the chassis plate and is molded from extremely high strength composite material. This connection allows you to unclip the rear end in one piece, but helps reduce the total cost of maintenance.

Serpent Spyder SRX-2 MM Mid Motor 2WD Competition Electric Buggy Kit
For 300 bucks, you're getting a good deal. Sure, the B5m is a little cheaper and most hobby shops have the parts in stock, but I just got rid of my B5m, I had for 6-1/2 months, it's a good buggy, but Associated went cheap on quite a few things..hence the low price. However on the Spyder, you get some very nice quality parts for only a few bucks more than the Associated.)

Serpent Spyder SRX-2 MM Mid Motor 2WD Competition Electric Buggy Kit
Great Buggy, Have been putting it through it's paces, Some things I would suggest in need of upgrading would be the O Rings for the shock bottoms, The diff nut should not be plastic (I had to use an associated screw and nut), The Idler gear does strip and would be best upgraded to the steel Idler when built, Bearings have seized in the out drives in the gear box (since replaced with associated bearings)
For the price and the limited time in production, With all the above taken into account, It is a very good choice and worth sticking with, Cant wait to see the next version.)

Great buggy easy build the only thing you need to change the shock O-rings to the X rings by traxxis or Kyosho and use the green slime from associated(1105) on your shock shafts and seals. Or your shocks will leak.great buggy lots of carbon fiber b5 has none. Buy this!!!! Lol)

Serpent Spyder SRX-2 MM Mid Motor 2WD Competition Electric Buggy Kit
Kit went together very well, shocks are amazingly smooth. 1/8" diff balls last way longer then even the new B5 diff. Picked it up after getting fed up with a twitchy C4.2 and despite being the only one at my local track running a Serpent I have managed to get it set up perfect with very limited changes from the box setup. I would recommend this buggy to anyone who wants to run something really fast but also different from what everyone else is running.)

What the B5M wishes it was. Great fitment. Carbon fiber shock towers and battery strap, adjustable skipper AND clutch without removing anything. LOW STOCK WEIGHT means you don't really need to purchase a ton of hop up parts.)

Serpent Spyder SRX-2 MM Mid Motor 2WD Competition Electric Buggy Kit
The only 2wd I havent owned is a Losi 22 2.0. But I have driven one. Ive owned pretty much every other brand and can tell you honestly this kit is a real pain in the butt. Shocks leak, bad o-rings. Gear diff, should you choose to buy one also has the same issue. One run and all the diff oils gone. Horrible ball cups, the most ridiculous idea ever I changed mine to B5M ones for durability and convinience. Horrible ball diff and lock nut. You have to use two aluminum idlers or the whole gear box will strip. However there is support for this car on FB, but its more like an AA meeting for people to complain. No one really has any answers on how to fix its issues. The car is just a pain to work on, a pain to fix constantly and yhere are better options. If I had to recommend a car for this class, buy a Kyosho RB6, or a B5M Lite. Youll love those cars and everything about them. If you want a PIA of a car that youre always wrenching on buy this, its no wonder people are selling these off for close to nothing. Even the build doesnt go smoothly. Dont have to take my advice, just trust all the feedback online, stay away.)
