The SRX8-E GEN4 refines Serpent’s 1/8 electric race buggy with chassis, shock, drivetrain, and battery layout updates aimed at easier tuning and improved performance. Kit ships at HK$4,749 (about $600 USD).
GEN4 focuses on refinement: new 7075-T6 lightweight chassis, redesigned shocks, and updated drivetrain parts for race-ready tuning.
Battery and weight options: saddle battery layout plus three shorty battery positions to tune balance and center of gravity.
Serviceability and parts: easier to tune and maintain with updated caster blocks, driveshafts, lightened spur gear, and premium NSK bearings.
Serpent announced the SRX8-E GEN4, the fourth-generation update to its 1/8-scale electric 4WD off-road buggy kit. The company describes this release as a set of targeted refinements rather than a ground-up redesign, with changes aimed at performance, tuning flexibility, and serviceability.
The kit includes a new 7075-T6 lightweight chassis. That material choice typically reduces chassis weight while keeping stiffness, which helps lower overall mass and can change handling balance.
Shocks were redesigned with 16 mm bodies and the rear shock standoffs are 4.5 mm longer. The combination of revised shock bodies and altered standoff lengths gives different spring and travel characteristics for tuning suspension response.
Drivetrain updates include an updated center differential and motor mount, Serpent's HTD differential system, updated V2 driveshafts, and a lightened spur gear. Those parts aim to improve drivetrain efficiency and durability while reducing rotating mass.
Other chassis and running gear updates are V2 caster blocks and the inclusion of premium NSK bearings throughout.
Serpent emphasizes easier tuning and maintenance. Concrete changes that support that goal include updated caster blocks and driveshafts, redesigned shock bodies that are likely to simplify spring and damper changes, and a lightened spur gear for easier drivetrain adjustments. Premium NSK bearings are specified, which reduces friction and maintenance cycles compared with lower-grade bearings.
The kit's part number is SER600025 and it is priced at HK$4,749, listed as approximately $600 USD in the announcement.
The GEN4 package is presented as an evolution intended for racers who want more straightforward setup options and lower rotating weight, while keeping the core SRX8-E layout familiar. The combination of a 7075-T6 chassis and the drivetrain/gear updates suggests this kit targets competitive 1/8 electric racing and advanced hobbyists who want a tuneable platform.
