Whether you’re bashing in the backyard, tearing up the race track, or crawling over rocks, there’s always room to push your RC car a bit harder and make it a bit better. The beauty of hobby-grade RC cars is their customizability—you can tweak, swap, and upgrade nearly every part.
In this post, we’ll break down the top 10 upgrades that will improve speed, handling, durability, and overall performance.
1. Brushless Motor Upgrade
One of the most noticeable performance upgrades.
Why Upgrade?
Brushless motors are faster, more efficient, and longer-lasting than brushed motors.Result:
More speed, better torque, and reduced maintenance.
💡 Pair this with a compatible Electronic Speed Controller (ESC) for maximum benefit.
2. LiPo Battery Pack
A Lithium Polymer (LiPo) battery offers more power than standard NiMH batteries.
Why Upgrade?
Higher voltage and better energy density = more power and longer run times.Result:
Faster acceleration and longer driving sessions.
⚠️ Make sure your ESC can handle LiPo batteries, and always use a proper LiPo charger and storage bag.
3. High-Performance Tires
The right tires can drastically change how your RC car handles.
Why Upgrade?
Factory tires are often general-purpose and may lack grip.Result:
Improved traction, control, and performance on specific surfaces (asphalt, dirt, sand, etc.)
🔄 Match your tire type to the terrain: slicks for pavement, knobbies for off-road, or beadlocks for crawlers.
4. Upgraded Suspension (Shocks and Springs)
Control your car’s bounce and improve its handling over rough terrain.
Why Upgrade?
Stock suspension can be too soft or stiff.Result:
Better stability, smoother landings, and improved cornering.
🛠 Consider oil-filled shocks for a customizable ride feel.
5. Steel or Hardened Drive Shafts
Stock plastic drive shafts can twist or break under heavy load or high torque.
Why Upgrade?
Steel drive shafts are more durable and transmit power more reliably.Result:
Better power transfer and reliability, especially for high-power setups.
6. Metal Gears
Plastic gears are often the first parts to wear out when you upgrade power systems.
Why Upgrade?
Metal gears resist wear and damage.Result:
Longer-lasting drivetrain, especially when running brushless motors or racing.
7. Upgraded Bearings (Full Ball Bearings Kit)
Ditch the plastic bushings and go with high-quality ball bearings.
Why Upgrade?
Less friction = smoother movement.Result:
Increased speed, improved efficiency, and reduced wear on moving parts.
8. Aluminum Parts (Arms, Hubs, etc.)
Aluminum is stronger than plastic but still lightweight.
Why Upgrade?
Better durability without adding too much weight.Result:
Less breakage, tighter tolerances, and better handling under stress.
⚠️ Use aluminum upgrades selectively—too much can make your car heavier and more brittle in crashes.
9. Programmable ESC (Electronic Speed Controller)
Control how your power is delivered.
Why Upgrade?
Set acceleration curves, braking strength, drag brake, and more.Result:
Custom driving experience, improved efficiency, and better tuning for racing or crawling.
10. 2.4GHz Radio System with More Features
If you’re still using an older or basic controller, this is a game-changer.
Why Upgrade?
Advanced radios offer features like throttle curves, dual rate steering, and multiple model memory.Result:
More precise control and better driving comfort.
Bonus Tip: Weight Reduction or Balance Tuning
Removing unnecessary parts or relocating components (like battery or ESC) can help with handling and responsiveness.
Especially useful in racing or crawling scenarios where weight distribution affects performance.
Final Thoughts
Upgrading your RC car is one of the most satisfying parts of the hobby. You can build something that not only performs better but is uniquely yours. But remember—don’t upgrade everything at once. Start with what matters most to your driving style and terrain.
