RC racers aiming for crisper handling will appreciate the Serpent 500504 4-Gear Laydown Transmission Kit for the Spyder SRX2 1/10 2WD buggy. By lowering and shifting weight forward, the package improves stability and increases traction on high-adhesion surfaces like carpet, clay and astro.
The four-gear setup softens acceleration compared to a three-gear system, helping drivers manage power through tight corners and complex layouts. Differential height inserts in the cases let you set high, center or low positions to suit track grip and driving approach.
Included is a precision 7075 T6 motor plate that locks to the chassis and case for a secure install. An aluminium chassis upgrade is required for fitting, and the kit contains the necessary parts when using an SRX2 MM donor. Detailed assembly instructions are available in the downloadable PDF manual.
This kit is aimed at competitors who want smoother power delivery and better front traction on high-grip surfaces, with adjustable options to fine tune handling across different tracks.
