Serpent 500504 1/10 SRX2 4-Gear Laydown Transmission Kit  [SER500504]

Upgrade SRX2 Handling with Serpent 500504 4-Gear Laydown

For RC hobbyists wanting better on-track control, the Serpent 500504 4-Gear Laydown Transmission Kit is a practical upgrade for the Spyder SRX2 1/10 2WD buggy. The laydown design moves mass forward and lower, improving stability and grip on high-traction surfaces such as clay, carpet and astro.

Tune Acceleration for Smoother Power Delivery

The 4-gear arrangement produces a gentler torque curve than a 3-gear setup, making the buggy easier to modulate through corners and over technical sections. The transmission cases include diff height inserts so you can choose high, center or low differential heights to match driving style and track grip.

Precision Parts for Cleaner Installation

The kit features a machined 7075 T6 motor plate for a solid connection between chassis and case. Installation requires an aluminum chassis upgrade, and when using the SRX2 MM as the donor car the kit supplies the needed pieces. Refer to the online PDF manual for full assembly steps.

This transmission kit suits drivers seeking more predictable throttle response and improved front-end traction on high-grip tracks. The adjustable diff heights let you fine tune balance for different circuits.
