Descripción

Enhance Your Driving Experience with the JNDO Reverse GearboxUpgrade your vehicle's capabilities with the JNDO Go Kart Forward Reverse Gearbox Kit, designed specifically for DIY assembly enthusiasts looking to add professional-grade functionality to their builds.This kit addresses the primary limitation of standard karts by enabling smooth shifting between forward, neutral, and reverse modes. By integrating this transmission, you gain significantly improved control and practicality, making it ideal for navigating tight trails or maneuvering in storage areas.Engineered for Performance and DurabilityDesigned to handle the rigors of off-road environments, this gearbox is constructed from high-strength aluminum alloy to balance weight and structural integrity.The internal precision steel gears and a high-strength alloy steel output shaft ensure consistent power delivery even under high-frequency use. With a forward ratio of 1:1.3 and a reverse ratio of 1:2.6, the system is optimized to enhance low-speed torque, providing the necessary grunt for 212cc to 420cc engines up to 13HP.Versatile Integration and CompatibilityThis transmission kit is a choice solution for a wide range of applications, including go-karts, golf carts, small agricultural machinery, and utility vehicles.It is specifically compatible with 30 Series Torque Converters featuring a 5/8" driven pulley.The package includes two different sprockets—a 12-tooth for #35 chains and a 10-tooth for #40/41/420 chains—ensuring it fits popular models and homemade projects like electric-to-gas conversions.Important Installation and Maintenance Notes1.Please note that the gearbox is shipped without gear oil to meet safety requirements. Users must fill the unit to half its height with standard gear oil before operation(you may use any readily available gear oil).2.Installation is recommended for experienced enthusiasts, as it requires a welding mounting bracket (not included) to secure the unit to the vehicle frame. 3.Always verify your vehicle's available space and compatibility with the 8.5cm length and 5/8" diameter output shaft before purchase.4.To ensure the gearbox maintains its factory-sealed condition, do not disassemble the gearbox, as this may easily cause gear oil leakage.If you find oil leakage from the gearbox during the initial gear oil filling, please contact us immediately and we will provide you with after-sales support.Comprehensive Package and After-Sales AssuranceThe JNDO kit comes with everything needed to get started: one reverse gearbox, a shifter lever, a cable equalizer, two 61-inch shifter cables, mounting brackets for the cables, and necessary sprockets.Your purchase is protected by a 14-day free return policy for any reason, and we provide a replacement for any product quality issues discovered within 6 months of use.
