Top 5 Upgrades for the VRX Cobra to Boost Speed and Handling

RH-818
The VRX Cobra is a great all-rounder for bashing and racing, but with the right upgrades, you can unlock much more speed, stability, and durability. Below are the top 5 performance upgrades every Cobra owner should consider.
Top 5 Upgrades for the VRX Cobra to Boost Speed and Handling 1
1. Upgrade to an 80A Brushless ESC (from 60A)
The stock 60A brushless ESC is capable, but stepping up to an 80A brushless ESC gives you more headroom for higher power setups.
  • Why it helps: Handles stronger current without overheating or cutting out.
  • Result: Smoother power delivery, higher top speed potential, and more consistent performance under load.
  • Tip: Pair the ESC with a quality brushless motor for maximum efficiency.

2. High-Capacity LiPo Battery
Switching to a high-capacity LiPo pack (e.g., 2S or 3S with higher mAh rating) is one of the easiest ways to boost performance.
  • Why it helps: Delivers higher voltage and discharge rates compared to NiMH or smaller LiPo packs.
  • Result: Faster acceleration, stronger punch, and longer runtime.
  • Tip: Always balance charge LiPos and store them properly for safety
3. CNC-Machined 38T/13T Gears
Although the stock metal powder gear is durable under 3S LiPo, it may not last long when running high output C-rate packs or stepping up to 4S LiPo.Upgrading to CNC-machined steel 38T spur gear and 13T pinion gear ensures maximum durability.
  • Why it helps: Precision-machined steel gears handle higher loads with less wear and increased drivetrain efficiency.
  • Result: Smoother gear mesh, less slippage, and reliable performance under extreme power.
  • Tip: Properly shim and lubricate gears to extend lifespan.

4. Aluminum Shock Absorbers
Oil-filled aluminum shocks are a must for better handling.
  • Why it helps: Stronger than plastic shocks, better heat dissipation,and consistent damping.
  • Result: More stable landings, improved traction on uneven surfaces,and enhanced cornering grip.
  • Tip: Experiment with shock oils (e.g., heavier oil for flat tracks, lighter for rough terrain).
5. Performance Tires with Harder Shore Compound
The right tire choice makes all the difference in how your Cobra grips the track.
Upgrading to performance tires with a harder shore compound reduces “booming” (tire deformation) and provides stable traction.
  • Why it helps: Harder rubber resists ballooning at high speed.
  • Result: More consistent traction, improved stability, and better control during acceleration.
  • Tip: Choose tread patterns based on your surface (slicks for asphalt, knobbies for dirt).

Bonus Upgrade: Adjustable Metal Suspension Parts
For drivers who want precise control, upgrading to aluminum suspension
arms, camber links, and turnbuckles is the next step.
  • Why it helps: Allows fine-tuning camber, toe-in, and ride height.
  • Result: Sharper steering response and more stability in high-speed
  • cornering.

Final Thoughts
With these upgrades — 80A brushless ESC, LiPo battery, CNC gears,aluminum shocks, and harder compound tires — your VRX Cobra will transform into a faster, stronger, and more stable machine. Add in adjustable suspension parts for fine-tuning, and you’ll have a buggy that performs like a pro on any track.
