Why Arrma Big Rock Upgrades Is Necessary
I found that upgrading my Arrma Big Rock became necessary pretty quickly because the truck is so much fun that I started pushing it harder than stock parts were really meant to handle. The more I drove it on rough terrain, jumped it, and ran it at higher speeds, the more I noticed weak points showing up. For me, upgrades were not just about making it look better—they were about making it stronger and more reliable.
My biggest reason for upgrading was durability. Stock parts can work fine at first, but once I started bashing regularly, I saw how quickly certain components could wear out or break. By improving things like suspension, driveshafts, tires, and steering parts, I was able to spend more time driving and less time fixing. That made the whole experience much more enjoyable.
I also realized that upgrades helped me get better performance and control. My Big Rock felt more stable, handled jumps better, and gave me more confidence on different surfaces after I made a few changes. In my experience, upgrading the Arrma Big Rock is necessary if I want longer life, fewer repairs, and a truck that performs the way I really want it to.
My Buying Guides on Arrma Big Rock Upgrades
When I first started upgrading my Arrma Big Rock, I quickly realized that not every upgrade is equally important. Some parts improve durability right away, while others are more about performance, handling, or convenience. In my experience, the best approach is to upgrade the areas that fail most often first, then move on to parts that make the truck more enjoyable to drive.
1. Start with Durability Upgrades
The first upgrades I usually recommend are the ones that protect the truck from breakage. On the Big Rock, I focus on stronger suspension arms, metal axle components, and reinforced shock towers if I’m planning to drive hard or jump often. These parts help me spend more time driving and less time repairing.
2. Upgrade the Tires and Wheels
One of the biggest improvements I noticed came from better tires. The stock tires are fine for general use, but I prefer upgrading to tires with more grip and better foam support when I want improved control. Good tires make a huge difference in how the Big Rock handles on dirt, grass, gravel, and pavement.
3. Improve the Suspension
For me, suspension upgrades are worth it when I want better stability and smoother landings. I look at shock oil, springs, and sometimes aluminum shock caps or towers. If the truck feels too stiff or bouncy, tuning the suspension can make it much easier to control at speed and over rough ground.
4. Consider a Better Servo
The stock servo can be a weak point depending on how I drive. If I notice slow steering or weak response, I upgrade to a stronger, faster servo. This is especially useful if I run the truck on rough terrain where precise steering matters.
5. Strengthen the Drivetrain
When I add more power or drive aggressively, I pay attention to the drivetrain. Metal or upgraded driveshafts, stronger diffs, and better gears can help the Big Rock handle extra stress. I usually consider these upgrades if I’m running higher voltage batteries or a more powerful motor system.
6. Choose Electronics Based on My Driving Style
Electronics upgrades are important when I want more speed, smoother throttle control, or better reliability. A quality ESC and motor combo can completely change the truck’s feel. I always make sure the electronics match my driving style, battery setup, and the kind of terrain I use most often.
7. Don’t Forget Cooling
Cooling is something I used to overlook, but it matters a lot. If I run my Big Rock hard, I like adding motor and ESC cooling fans or heat sinks. Keeping temperatures under control helps protect my electronics and keeps performance consistent.
8. Focus on Protection Accessories
I also like using small protection upgrades such as chassis guards, mud guards, and body reinforcement. These parts may not seem exciting, but they help reduce wear and tear. In my experience, a little protection goes a long way when driving in dirt, wet grass, or rough conditions.
9. Upgrade in the Right Order
If I had to buy upgrades in order, I would start with the parts that prevent failure, then move to handling improvements, and finally look at speed and performance upgrades. That way, I’m not wasting money on power upgrades before the truck is ready to handle them.
10. My Final Buying Tip
My biggest advice is to buy upgrades based on how I actually drive, not just what looks good online. If I bash hard, I prioritize durability. If I race or drive on smooth ground, I focus more on handling and electronics. The best Arrma Big Rock upgrades are the ones that solve the problems I really have.
Final Thoughts
In my experience, the best Arrma Big Rock upgrades are the ones that improve durability, handling, and overall control without overcomplicating the build. I’ve found that starting with the weak points and upgrading those first gives the biggest performance boost for the money. My takeaway is simple: choose upgrades that match how you drive, and the Big Rock becomes a much tougher and more enjoyable truck to run.
