WPL Motor Upgrade Kit With 2-Speed Gearbox
This WPL upgrade kit provides a direct bolt-on solution for WPL C14, C24, and C34 models. Its plug-and-play design uses factory mounting points, preserving suspension geometry for authentic handling across trails, rocks, and scaled terrain. The 2-speed metal transmission delivers smooth, distinct shifts between low and high gears, enabling strong crawling torque when navigating obstacles and elevated speed for open runs. A reinforced metal-ABS hybrid housing safeguards the internal gears against impact and repeated shifts, supporting long-term reliability during aggressive crawling sessions and outdoor use.
2 Speed Transmission Gearbox With Metal Internal Gears
Designed for 1/10 scale TRX4 and TRX6 crawlers, this gearbox uses metal internal gears and bearings to boost durability and performance. The gears feature hard anodic coating and anti-rust treatment, extending service life under demanding use. The upgrade aims to improve overall RC performance with better torque at low gear and stronger top-end speed in high gear. Its robust construction and precision machining minimize backlash, promoting more predictable gear shifts and smoother operation during rock crawling and rocky terrain navigation.
2 Speed Gear Box For HSP 94102/94122
This replacement gearbox is tailored for HSP 94102/94122 models, providing an easy upgrade path with standard sizing for straightforward installation. The 2-speed configuration is aimed at delivering stronger crawling capability in low gear while maintaining reliable top speed in high gear. It emphasizes smooth gear engagement and quiet operation, reducing noise during runtime and improving driving comfort on varied surfaces.
INJORA LCG Complete Transmission Gearbox
The INJORA LCG gearbox combines plastic and aluminum components for a balance of durability and weight reduction. Its low center of gravity design enhances stability, particularly on steep inclines and uneven terrain. Hardened steel gears deliver smooth, dependable driving performance, supporting consistent power transfer across both speeds and improving control during technical maneuvers and rock crawling. The design prioritizes reliable alignment and reduced heat buildup during intense use.
2-Speed Transfer Case With Steel Gears
This 2-speed transfer case is built with durable aluminum housing and steel gears, designed for off-road endurance. The selectable gear ratios—1.8:1 for climbing and 0.7:1 for higher speeds—enable tailored performance across varied terrains. Wide 48-pitch steel gears ensure strong mesh and efficient power transmission. It is suitable for 1/10 scale crawlers and provides a robust upgrade path for vehicles used in rock crawling, trail running, and challenging courses.
Buying Guide: Key Considerations For Choosing A 2-Speed RC Gearbox
- Compatibility: Verify model compatibility (scale, chassis, and mounting points) before selecting a gearbox. Some kits require specific model families or chassis adjustments.
- Drive Efficiency: Look for gearboxes with low-gear torque and high-gear top speed balance to optimize crawling ability and trail speed without sacrificing durability.
- Gear Material And Build: Metal internal gears, hardened steel components, and durable housings (metal-ABS hybrids or aluminum) generally offer longer life under high-torque conditions.
- InstallationEase: Consider bolt-on or plug-and-play designs to minimize modifications and preserve suspension geometry, especially for scale appearances.
- Weight And Center Of Gravity: Heavier gearboxes may affect handling; lighter designs with a low center of gravity improve stability on uneven terrain.
- Maintenance: Check for straightforward disassembly and lubrication options to sustain performance and reduce wear over time.
- Noise And Heat: Some units run quieter and cooler; these aspects support longer sessions and better driving experience in trails.
