JRRXM 2-Pack Large Aperture RS555 Gearbox for Power Wheels – 24V/30V/36V High Torque, 12000–18000 RPM

Upgrade your ride-on car with confidence

The JRRXM 2-Pack Large Aperture RS555 gearbox set is designed to elevate your child’s Power Wheels experience. This upgrade pair combines two aperture sizes—a primary 1.9 cm (0.74 in) opening and, after inserting a sleeve, a 1.6 cm (0.61 in) option—offering flexible compatibility with different housings. The design intentionally avoids the traditional 1.2 cm aperture, helping you verify a precise fit before purchase. The result is a more robust drivetrain that can support higher torque demands while preserving smooth operation.

Two aperture options for a precise fit

• Large aperture: 1.9 cm for a snug, secure fit in many Power Wheels housings.
• Smaller aperture with sleeve: 1.6 cm to accommodate tighter spaces without sacrificing performance.
• Distinct from common 1.2 cm variants, designed for flexible installation planning.

Durable construction for long-lasting performance

• Motor core: RS555 with a pure copper coil for efficient energy transfer.
• Gear materials: steel gears in the core stack to boost lifespan and torque resilience.
• Heat management: four-hole cooling design helps dissipate heat during extended use.

Voltage range and speed options

These gearboxes are compatible with multiple voltages within a safe range. At 24V, expect around 12000 RPM; at 30V, around 15000 RPM; and at 36V, around 18000 RPM. The output speed ratio is approximately 1:100, enabling strong takeoff while preserving control. Do not exceed 36V to protect components.

Easy installation notes and real-world use

• One-button motor cable option may simplify wiring during upfit; follow the included guidance.
• Before purchasing, compare the size of your original gearbox to confirm fit and recommended voltage.
• Professional pre-sales and after-sales support are available for questions about compatibility.

What you get and practical benefits

Two high-speed RS555 motor gearboxes designed for ride-on cars, built to withstand repeated use while delivering improved takeoff performance. Potential advantages include quicker acceleration, better hill-climbing capability, and steadier speed transitions, depending on your specific setup and power source.
