Mini 4WD Super Speed Gear (for MS Chassis)

The Hobby Hideaway Verdict: Demolish the Competition on the Straights! If your local track layout features long, blistering straightaways, this is the upgrade you need. Originally included with touring car-style Mini 4WD PRO machines, this super-fast 3.5:1 ratio gear set is designed to kick your top-end speed up to the absolute maximum. At Hobby Hideaway, we highly recommend this Grade-Up part for racers looking to outpace the pack and dominate their heats with raw, unadulterated speed.

Unlock Touring Car Speed for the PRO Series Gear ratios determine the balance between acceleration (torque) and top speed. A 3.5:1 ratio represents the highest top-speed option available for the PRO series, meaning your wheels will spin faster for every rotation of the motor compared to standard gears. This set is engineered specifically for the dual-shaft motor design of the Mini 4WD PRO platforms, making it a direct drop-in upgrade to completely change the dynamic of your machine.

Key Features & Technical Specs:

• Extreme Top Speed: Features a super-fast 3.5:1 gear ratio designed to maximize straight-line momentum.

• PRO Series Exclusive: Specifically designed for dual-shaft motor chassis (like the MS and MA platforms).

• Direct Upgrade: An official Grade-Up parts set that easily replaces your stock gears.

• Incompatibility Note: NOT compatible with Dangun racers or standard single-shaft non-PRO series chassis (like AR, VZ, FMA, etc.).

Hobby Hideaway Pro Tip: Because a 3.5:1 gear ratio sacrifices a little bit of low-end torque in exchange for massive top-end speed, it can sometimes struggle to regain momentum right after tight technical corners or when climbing steep slope sections. To get the best of both worlds, pair these gears with a motor that delivers strong, punchy torque—like a Hyper-Dash PRO or Mach-Dash PRO. This combination will give you the acceleration you need out of the corners, and the gearing will let that motor scream on the straights! Always remember to apply a light dab of gear grease during installation to keep the mesh running smoothly.
