The First Upgrade You Should Do on Any New RC Truck
You just dropped some serious money on a new RC truck. It's charged up, you've been ripping it around, and now you're thinking about upgrades. New tires? Metal steering parts? A body kit? I get asked this question every single day at the shop, and after 30 years of selling and running RC trucks, my answer might surprise you.
Before You Spend a Dime on Upgrades — Do This First
The very first thing you should do with any new RC truck isn't an upgrade you buy — it's something you do to the truck you already have.
Seal your tires. Tape up or silicone the ventilation holes in the rims. If water, sand, or mud gets inside your tires, your day is over. The tires become unbalanced, heavy, and the glue starts failing. Five minutes of prep prevents the #1 problem I see at the track and the beach.
"The best thing to do, period, when you get a new truck is tape up the holes in the tires or silicone 'em up. If you get water in there, they suck. And make sure they're super glued. Take the time before you go out — get some alcohol, clean the inside of the rim where the ventilation hole is, and tape it up or silicone it up. Bring some extra glue too, 'cause once sand gets in there, you're in a bad place." — Matt, RC Hobby Pros
And while you're at it — check your motor mount and pinion gear. This is the single most important thing you can do for ANY RC car, period, in history. Tighten the motor mount screws. Make sure the pinion is snug against the spur gear with the right mesh. Put a tiny drop of blue Loctite on those bolts.
"Tightening the motor and pinion gear is the best thing you can do for any RC car, period, in history, and it always will be. Loctite on both. I see so many cars where the motor's loose — some of these newer cars you can drive 'em with the motor loose and they still work, but back in the day that would've stripped the gear instantly. Just check it. They're not always super tight from the factory." — Matt, RC Hobby Pros
The #1 Upgrade That Actually Matters: An Extra Battery and Better Charger
I know it's not the sexy answer. You want new wheels. You want a faster motor. But hear me out — the upgrade that gives you the most additional fun per dollar is a second battery and a quality charger.
"It kinda sucks 'cause you just dropped five bills on a new car, but another 150 or 200 on a really good battery and charger — that's the number one thing that's gonna unlock more fun minutes for you. It's gonna be quicker to charge and give you more minutes of play. Literally a new battery and charger is gonna double your runtime from what you already have 'cause you're gonna have two batteries and two chargers too." — Matt, RC Hobby Pros
Think about it: you drive for 20 minutes, battery dies, and you're done. OR you drive for 20 minutes, swap batteries, and you're right back at it while the first one charges. That's double the fun time. No upgrade in the world beats that.
And keep your stock charger. Even if it's basic and slow, it's still useful for topping off a second battery while you run the first one.

After That — Here's Where to Spend Your Money
A better steering servo. The stock servo in most RTR trucks is... fine. But if you've got big heavy tires and you're bashing hard, a faster, stronger servo makes a real difference in how responsive the truck feels. Brands like Savox, Spektrum, and Reef RC make excellent options.
For crawlers specifically, we stock those Reef RC servos — they look like polished brass, they're insanely powerful, and the crawler guys go nuts for them.
A cooling fan for the motor and ESC. This is practically a given for any brushless truck. A little fan on the motor and one on the speed controller keeps temps down, which means more consistent power and longer component life. Cheap insurance.
Gear it down one or two teeth. I know everybody wants to go faster. But dropping the pinion gear by a tooth or two gives you more torque, lower temps, and better reliability — especially if you're running on grass, sand, or doing a lot of jumping.
"Sometimes I gear it back one or two teeth — it gives you more reliability, keeps the temp down. Everybody wants to go faster, but sometimes gearing down is the move. Especially if you're running on the beach or in grass." — Matt, RC Hobby Pros
The Underrated Maintenance Upgrades
These aren't flashy but they'll keep your truck running longer than any part swap:
Blue Loctite. Put it on every critical bolt. Motor mount, shock towers, servo screws, wheel nuts. Costs a few bucks and prevents half the problems I see come through the shop.
A damp rag. Seriously. After every run, just wipe the truck down. It sounds too simple to matter but it goes a lot further than you'd think.
"A damp rag is so underestimated in this world. We've been trained to buy chemical products, but even your real car or your RC car — just get a damp rag and wipe the thing off. It goes a lot longer than you would think." — Matt, RC Hobby Pros
Armor All Foaming Tire Cleaner. This is my secret weapon. That white foam spray you use on real car tires — spray it on your RC truck after a run. It cleans it off and leaves a light coating that helps protect against salt and grime. Works great after beach runs especially.
