Serpent 904003 Viper 977-e EVO2 - Competition Ready 1/8 Chassis

Designed for racers who like to fine tune every corner, the Serpent 904003 Viper 977-e EVO2 blends durable materials with a setup-first layout. The kit aims to simplify adjustments while standing up to hard running at events.

Stiff Base and Efficient Drive

The platform pairs a 5mm aluminum base with a 2.5mm carbon fiber top deck to control flex and weight. A dual-belt arrangement with ball-raced tensioners reduces power loss, and the front one-way plus solid rear axle setup helps maintain consistent handling through acceleration.

Adjustments for Different Surfaces

Independent double wishbones allow precise changes to camber, caster, toe and roll center so you can adapt the car to varied grip levels. Low-profile big bore shocks offer predictable damping for fast sweepers and tight infield sections.

Service Friendly Component Layout

Battery and motor mounting are designed for fast access during race day. Adjustable carbon battery holders take common 2S and 3S LiPo packs to help tune front to rear weight, and the aluminum motor mount is built to handle high power brushless systems.

The Serpent 904003 Viper 977-e EVO2 is a reliable base for racers who value tunability and durability. It provides a clear path for setup refinement across different tracks and conditions.

Many clubs allow custom 1/8 electric touring kits but check specific class rules. The chassis layout and drivetrain are typical for competitive 1/8 on-road events.
The adjustable carbon battery holders let you move cells fore or aft to shift the centre of gravity and fine tune understeer or oversteer tendencies.
Tyre choice depends on surface grip; medium compound slicks suit high grip circuits while harder compounds help on abrasive or dusty tracks. Pair tyre choice with damper settings for best results.
Yes, 2S packs fit the battery holders and provide gentler power for practice and setup work; ensure ESC and motor are compatible with the chosen cell count.
