Performance Upgrades for Maximum Speed
Speed is what makes the Traxxas Rustler 4x4 VXL legendary, but with a few smart upgrades, it can go from quick to jaw-dropping.
The stock setup is already impressive, but tuning its power system, gearing, and tires unlocks a level of acceleration and top-end speed that even seasoned RC drivers respect.
So, if your goal is pure speed, these are the best upgrades for Traxxas Rustler 4x4 VXL - proven mods that deliver real, track-tested gains.
1. Brushless Motor and Gearing Adjustments
The Velineon brushless system that comes standard is fast, but a few tweaks can take it further.
Many drivers pair the stock Velineon 3500 motor with an upgraded ESC or switch to a high-RPM brushless combo for better torque and top-end pull.
Matching that power with a higher-tooth pinion gear or smaller spur gear gives a cleaner power curve and serious straight-line gains.
Pro tip: Keep an eye on motor temperature: every gearing increase adds speed but also heat. Adding a small cooling fan or heatsink can help you push harder without thermal shutdown.
2. Battery Upgrades for 70+ MPH Runs
Switching from a 2S to a 3S LiPo battery is the simplest and most noticeable speed upgrade you can make.
The Traxxas 3S 5000 mAh LiPo offers more punch, faster acceleration, and a top speed that can clear the 70 mph mark with proper gearing.
Choose 25C or higher discharge rates for consistent power delivery during longer runs.
Note: Always balance-charge your LiPo packs and check voltage limits. Speed means nothing if your pack puffs after three cycles.
3. ESC Tuning and Mode Settings
The built-in ESC offers selectable drive modes: Training, Sport, and Race.
Switching from Training to Sport or Race mode releases the Rustler’s full potential.
For advanced users, pairing the ESC with the Traxxas Link app allows fine-tuning of throttle curves, braking, and punch control. It’s the difference between “fast enough” and “perfectly dialed in.”
4. Low-Resistance Tires and Aerodynamics
Lightweight, low-drag tires such as the Traxxas Anaconda 2.8" tires reduce rolling resistance and give you better straight-line stability.
Combine that with a low-profile body or aero wing to cut drag and keep the Rustler planted at high speeds.

Handling and Suspension Upgrades
When you start exploring the best upgrades for Traxxas Rustler 4x4 VXL, the suspension is where real control begins.
The stock setup handles rough terrain well, but higher-end components bring precision, smoother landings, and tighter cornering that transforms how the truck feels on dirt, asphalt, or track.
1. Aluminum Shocks and Shock Towers
Upgrading to aluminum GTR shocks makes an immediate difference. They hold more oil than stock, resist heat fade, and take heavy jumps in stride.
Pair them with CNC-machined aluminum shock towers to stiffen the chassis and eliminate unwanted flex - the foundation for any performance setup.
Pro tip: Preload and spring rate adjustments let you dial in ride height and suspension response for racing or bashing.
2. Adjustable Turnbuckles and Camber Links
If you want predictable steering at full speed, start here.
Adjustable turnbuckles and camber links allow small alignment changes that help your tires grip better during acceleration and cornering. They’re a must-have if you’re switching between surfaces or tires regularly.
3. Performance Tires for Grip and Stability
Speed upgrades don’t mean much if your tires can’t hold the surface.
For off-road use, tires like the Traxxas Talon EXT 2.8” provide deep tread for grass and loose dirt. For street or track, Anaconda 2.8” slicks deliver reduced roll resistance and stable cornering. Most come pre-mounted, so installation takes minutes.
4. Center Driveshaft and Differential Upgrades
A heavy-duty center driveshaft helps balance torque delivery between the front and rear, while upgraded metal differentials prevent stripping during aggressive launches or high-speed runs.
Together, they keep handling consistent even under higher loads from upgraded motors and 3S LiPo packs.
Tip Box
Pro Setup Tip: Combine new shocks, adjustable links, and tire upgrades together. Each improves handling on its own - but together, they keep your Rustler planted through turns, jumps, and rough terrain.

Durability and Protection Mods
Every Rustler driver hits that moment: the landing’s too hard, the corner too wide, the crash inevitable. That’s when you realize the stock parts did their job and it’s time for components built to take real hits.
The Traxxas Rustler 4x4 VXL is tough out of the box, but repeated runs, bigger jumps, and brushless power eventually find the weak spots. Reinforcing the chassis and drivetrain keeps your setup running smoother, longer, and ready for more power when you add it.
1. RPM Arms and Chassis Braces
Upgrading to RPM suspension arms or aluminum chassis braces is one of the best first steps.
They’re built from high-grade composite or machined aluminum to handle flex and impact better than stock plastic parts. These pieces absorb shock on landings and protect key mounting points, saving you time (and money) on repairs after harder sessions.
2. Aluminum Caster Blocks and Hub Carriers
Metal caster blocks and hubs are small changes with a big payoff.
They stabilize steering geometry, prevent cracking under impact, and keep the front end aligned even during repeated collisions. Traxxas aluminum carriers also resist bending and provide smoother bearing rotation, which translates to consistent handling run after run.
3. Skid Plates and Chassis Guards
Adding front and rear skid plates helps your Rustler slide over rough terrain instead of digging in.
These parts protect vital components (like the motor housing, driveshafts, and differential casing) from rocks and debris. For all-terrain bashers, a full chassis guard set can extend the life of your undercarriage dramatically.
4. Cooling Fans for Motor and ESC
High-speed runs and 3S LiPo setups generate serious heat. Installing compact cooling fans for your ESC and motor can prevent thermal shutdown and extend component life.
Traxxas’ own cooling kits bolt directly on and plug into the receiver box - a simple, high-value protection upgrade for any performance build.
Tip Box
Durability Insight: Lightweight parts are great for speed, but metal and reinforced composites win for longevity. Focus on components that strengthen your Rustler’s chassis, suspension mounts, and drivetrain first - they protect every other upgrade you’ve made.

Servo and Steering Upgrades
If speed defines how fast your Rustler goes, steering defines how well it handles getting there.
The stock Traxxas 2075 digital servo is waterproof and reliable, but it starts to feel underpowered once you add stronger motors or heavier tires.
You’ll notice slower response through corners and more steering fade during long runs.
Upgrading to a servo with higher torque and faster transit speed gives you tighter control, sharper correction, and more consistent handling under load.
1. Upgrade to High-Torque Servos
The Traxxas 2075R or Traxxas 2255 High-Torque Metal Gear Servo are direct-fit replacements that offer more precision and durability.
If you want something even stronger, Savox 1258TG or Power HD 20KG servos deliver quick, consistent response for tighter turns and smoother corrections on rough terrain.
Pro tip: Pair upgraded servos with an aluminum servo horn for added strength - it’s a small part that saves you from stripped splines or sloppy steering feel.
2. Steering Bellcrank and Linkage Kits
Upgrading to an aluminum steering bellcrank stiffens steering input and reduces flex under pressure.
Combined with adjustable turnbuckles, it lets you set precise toe angles and maintain stability at higher speeds.
It’s a simple change that immediately improves feedback through the transmitter - every turn feels tighter, more controlled, and more predictable.
3. Bearings and Waterproofing
If you’re running in wet conditions, adding sealed bearings around the steering assembly helps keep debris out and movement smooth.
Many modern servos, including Traxxas’ brushless models, are already IP67 waterproof-rated, giving you freedom to drive through puddles or wet grass.
Tip Box
Steering Setup Tip: When installing a new servo, center it before mounting the horn - then fine-tune your trim through the transmitter. A correctly aligned servo makes the difference between clean lines and constant corrections.
